Drawings for laser cutting. Laser cutting of plywood. Equipment with capabilities

Souvenir products made using laser technology appeared on the market relatively recently and in a short time created a separate direction in the souvenir industry.

The market offers consumers products made from different materials And for various purposes: promotional souvenirs, toys, kitchen utensils, interior items, items with individual design. New laser technologies: engraving on metal, wood, glass make it possible to create products for a wide variety of applications. In this article we will look at the use of lasers when working with plywood.

What are the advantages of laser engraving and plywood cutting?

Laser cutting of plywood ensures maximum accuracy of transferring a given image onto the surface of the material. The use of a laser differs from milling in that the cut edge is of a higher quality and does not require further processing. A focused laser beam cuts out millimeter-sized elements of a pattern while maintaining the dimension of a given element, which is inaccessible to a cutter. Using a laser allows you to save material, since there is no waste in the form of sawdust.

Scope of application of this technology:

2. Production of furniture and decorative interior elements. The use of laser cutting makes it possible to produce products with high detail, which is not available when using a metal cutter or milling cutter.

For understanding technological process laser cutting of plywood, Endurance Laser Lab specialists will step by step illustrate all stages of production souvenir product from plywood. Today we will carve a tea house.

Laser-cut blanks for a tea house are often sold in arts and crafts stores. Let's see how they are made using equipment from Endurance!

To create ready product, we will do the following steps:

Let's create a drawing of a tea house.
Let's connect the laser engraver.
Let's load the drawing into the software for the laser engraver and set the program settings for cutting the material.
Let's install the material (sheet of plywood) in the working field of the Endurance Laser Lab engraver.
Let's make sure that the printing area does not extend beyond the plywood sheet.
Let's launch the plywood cutting program.
Separate the resulting parts from the base and glue them together.

Creating a drawing for laser cutting of plywood

For creating complex drawings Endurance laser laboratory specialists recommend using the CorelDRAW graphic editor. In the case of a tea house we will take finished drawing as a jpg image.

Initially, we planned to make a tea house using a laser engraver Endurance Makeblock XY 2.0 plotter with a wide working area of 31 by 39 cm. This would allow us to load the drawing in one file and produce all the structural elements in one step.

At the time of writing, the sales department reported that all Makeblock model engravers are sold out and they are ready to give us an Endurance DIY desktop laser engraver for experimentation. The working area of this model is 20*20 cm. This meant that we would not be able to fit all the parts of our house into the working area of the cutter.

I had to cut the drawing into separate parts and cut them out one by one.

Connecting the Endurance DIY laser engraver - step by step instructions

There were no problems here. Devices from Endurance Laser Lab usually work without problems. We load the drawing into the software for the laser engraver and set the program settings for cutting the material.

To work with laser engraver Endurance DIY we used the popular CNCC Laseraxe program version 2.53. This software has quite a wide range of functionality and is free. You can download CNCC Laseraxe on our website. The program does not require installation. The interface is somewhat confusing at first glance, but it won’t take much time to understand the program.

1) Launch the program and connect to the laser engraver by pressing the Connect button. Then open the drawing with the Open button.

2) We process the drawing by pressing the PR button and selecting the upper right drawing of the hare.

3) Set the burning time and laser power to maximum. Press the Advan button.

4) In the changed window, check the setting of the vertical sliders, which should correspond to the picture: the top one is set to Outline, the bottom one is set to Path/Speed. Then we create g-code by clicking the Create button.

5) The program prompts you to go to the page with the code. Click “Yes”.

6) Before sending the design for burning/cutting, we need to check whether the laser is positioned correctly in relation to the material. Check the box in the WS window. The laser indicates the point from which the engraving/cutting process will begin. We place the material in accordance with the laser point and start the process by pressing the Run button. To cut through the material, you need to start the laser several times manually using the Run button. The harder the material, the larger number time you need to start the process. We used soft material- balsa for aircraft models. It took 5 laser starts to cut through 4 millimeters of balsa.

This is what the manufactured elements of the house looked like.

And this is how the house turned out after connecting the parts.

Conclusion

We demonstrated laser cutting of plywood and step by step production plywood souvenir using Endurance lasers. All important nuances and the intricacies of working with plywood and setting up laser technology cannot be described in one article. Therefore, we tried to provide information about working with plywood in the most general terms, deliberately not touching upon the issues of choice of materials, thickness and type of plywood, laser power, etc. A more detailed analysis of work in this direction will be published in separate articles after studying and conducting practical experiments.

For all questions about working with laser technology, you can contact our office. There you can familiarize yourself with our products and purchase laser equipment.

Drawings for CNC laser: materials for work, drawings, models

Modern computer technologies, if not completely eliminated the need to use manual labor, then we reduced it to a minimum for sure. The use of laser machines is also gaining more and more fans every year.

CNC laser machines refer to a whole range of devices designed for processing various surfaces. Management is carried out using computer programs.

Dear machine tool builders, we have selected a large number of models for you in dxf format, you can download them for free HERE.

What materials can be processed?

The device is used for processing and creating patterns on many types of surfaces:

Mirror.
Glass.
Stone.
Acrylic.
Leather.
Paper.
Cardboard.
Tree.
Veneer.
Plywood.

And this is far from full list possibilities of using CNC cutting. Application contactless technologies will allow you to process even materials of small thickness. Recently, automation of such work was considered impossible in principle. As well as simple creation of drawings for a CNC laser.

Operating principle of the device

Currently, any laser equipment has an acceptable price level. That’s why it is gaining popularity and is used not only in large but also in small businesses. Indispensable assistants The drawings with templates presented in this section will also become available. At the same time, high-quality work and high productivity are characteristic of even the most budget models.

To correctly use drawings using cutting, you need to understand what the machine consists of:

One-piece frame.
A table located in a horizontal plane.
Mobile portal. It is equipped with a special head that emits a laser beam.

A stepper motor allows you to set the equipment in motion. A numerical program circuit organizes the adjustment of all parameters. A Numerical Control device installs the laser at certain positions along with other devices that perform work operations.

The assembly optics unit also has several components.

Laser tubes.
Emitter in the form of a head.
Reflective devices with the shape of mirrors.
Focusing mechanism.
Focus lens.

Equipment with capabilities

This equipment has the main working tool - with laser base. It is distinguished by a high power rating. Thanks to this, it becomes possible to process materials endowed with parameters different types. Thanks to such technologies, it is possible to obtain parts with different characteristics and dimensions.

The capabilities of laser installations are worth considering in more detail in order to correctly use patterns with templates.

This affordable option technology, although not the most effective. Laser cutter consumes less energy than its plasma counterpart when performing the same work. Even when using heat treatment. The advantage of this type of cutting is the accuracy of the edges and the ability to preserve optical properties.

Cutting is done through or through. The use of the second option is relevant in the case of making souvenirs. Laser processing helps to quickly remove the top layer of plastic. This allows you to form a pattern on the surface of the second layer. Such jewelry work can only be done by laser and CNC machines.

This solution has its own operating principle. Thin through cuts are applied carefully, step by step. After this, a line is drawn up with the necessary dimensions. It doesn't matter how complex the image is, how thick the material is. The main advantage of laser engraving is maintaining high speed.

In what areas is the equipment used?

This important point for those who are just about to purchase machines.

Creation of souvenir products.

In the production of souvenirs, laser machines have shown high efficiency. It has already been said that non-contact processing makes it possible to create patterns on parts with any parameters. Which makes the entire work process easier. Even pens and USB keys are processed using this technology.

Information, award products.

Laser machines are convenient to use for making signs with any information. Diplomas made of two-layer plastic, award certificates - and in this area laser machines have practically no equal. The main thing is to choose the right drawings.

The equipment is especially relevant when creating interior and exterior elements. After using the machines, surfaces made of acrylic and plexiglass look good - they have a glossy end, and there are no radii left from the cutter. The smaller the element, the easier it will be to cut it when plasma cutters are used.

Laser cutting technology has become widely used in interior design. We are talking about the manufacture of overhead elements, decorating furniture, creating radiator and ventilation grilles. Usually we are talking about elements with a small thickness, fragile.

It is almost impossible to produce such parts using milling machines, because it is difficult to avoid the appearance of chips and cracks and other similar defects. Children's toys and constructors individual elements interiors can also be made using this cutting technology.

This area is also characterized by the active use of laser cutting of veneer. Especially when it comes to the production of marquetry and inlay. In the Hermitage, many objects were created using this technology.

Packaging work, changing the structure of foam rubber and plastic products.

Few people will be surprised by packaging made using laser machines. The equipment is convenient because it can be easily and quickly programmed at any time. There is no need to be tied to a specific circulation or set up complex lines for supplying materials. The surface is free of creases during non-contact processing. The surface of the pattern looks beautiful.

The width of the processing zone is usually indicated in the first article of the designation of a particular model. When choosing a particular device, you must always remember the possibility of encountering the need to solve non-standard problems. How larger size working area– the greater will be the range of tasks that are set for workers.

The following factors must be taken into account during operation.

Laser engraving can be used without creating printing forms, cliches and matrices. Accordingly, there is no need to purchase additional equipment or involve more people in processing.

Most operations can be easily performed at home. Just like the preparation of the drawings itself. Cutting them won't be difficult.

This saves time spent on pre-press processing. The production process is accelerated, the productivity of any installation becomes better.

Laser technology is known for not requiring any large quantity materials.

Without the laser itself, engraving cannot be performed. The installation is powered by regular electricity. One laser should be enough for approximately 20 thousand hours of continuous operation. Intensive use of one device can last up to 7 years. Even if cutting is carried out constantly.

One operator is quite capable of servicing the installation. The main requirement is the ability to work with graphics programs.
Products can be manufactured in both small and single batches. For the design of drawings and their direct production, working files are created in a special program.
The result of any work is obtaining durable images that are resistant to any influence. external factors. The drawing can be saved for future use.

Laser engraving: more about the technology

When using this technology, it is assumed that the material is removed from the surface of the workpieces by sublimation. The result is achieved by exposing the surface of the material to a focused laser beam. Maximum power is maintained when cutting. The main thing is to correctly manage the installation parameters to achieve the desired result. Laser engraving works on many of the same principles as a printer. The equipment is as convenient as possible due to the fact that almost no step is carried out manually. This is only required when preparing drawings. And in its finished form, the image will last as long as possible, without any damage.

Program for CNC plasma creation of drawings: features of work

The work is greatly facilitated when CNC plasma programs are used; the creation of drawings in this case is faster. The main thing is to set the parameters correctly and understand how the technology works.

About special programs and working with drawings

Thanks to modern laser machines, as well as programs for CNC plasma and drawing creation, you can easily process workpieces from any materials, ensuring high intensity of the process along with quality. But modern technologies have by no means contributed to the fact that humans are completely excluded from the technological chain. Operators are only freed from participation in the workpiece manufacturing process itself.

In order to obtain the required result for CNC, it is necessary to comply with the main conditions, which include the proper level of production preparation and the development of machine control programs.

The essence of any software used in control is the creation of a set of codes that undergo transformation inside the CNC microcontroller, and then become pulses when they enter the execution mechanisms. The function of the latter is transferred to stepper motors or servomotors. But the latter option is used only for some machine models. It is important to choose the right program for creating a drawing.

Electric motors are used during the transformation of impulses, after which the latter become mechanical movements for the instrumental part. The supporting spindle and cutter are involved in the same process. A unique route is laid inside the program, which is subsequently implemented by the machine. How the cutter moves relative to the future workpiece depends on this. Thanks to modern technologies It becomes easy to provide the required speed and cutting force. Flame processing also makes the process easier.

A separate file is created inside the control program, which must be processed further. What does the choice of modern software imply? But you need to create a preliminary sketch of the future product, because the route cannot appear out of nowhere.

Processing program

Products are created on the basis of sketches, the role of which is transferred to three-dimensional mathematical models. The participation of a plasma cutter is organized at later stages. This name is given to an exact copy of the structure, which is recreated in virtual space.

In some ways, 3D models are similar to assembly drawings. These models are created based on “flat” two-dimensional models. For example, which are the part drawings. It is their construction that becomes the main function for special CAD programs. The AutoCad function package is a typical representative of such solutions, which involves processing using plasma cutting.

Such solutions can be described as systems automatic design. In industry and design bureaus, this tool has long become an indispensable assistant. The entire cycle that makes up the process of developing documents for designers is made easier and simplified thanks to packages of similar software solutions. This also applies to creating sketches for parts using plasma cutting, modeling technology in a three-dimensional plane, and developing parts for assembly. The so-called CAD packages are the basis on which control programs are created, the results are sent to the machines themselves, which allows production to begin. Next, plasma takes part in the processing.

Features of working with equipment

A typical strategy that is used can be described as follows: CNC milling machines when products are created:

The stage dedicated to creating a sketch or drawing.
Previous work becomes the basis for developing models in three dimensions.
Setting a route when using software. The three-dimensional model now becomes the basis on which this very route is created.
Then they proceed to export the control program using a special format. The main thing is that the format is understandable to the laser machine model itself.
Loading the control program into the device memory. After which the processing program is launched.

First stage

At the first stage, it is impossible to do without a thorough study of the design documentation. It is expected to use drawings for small components and assembly units, a large amount of materials when developing detailed drawings. On the drawings, specialists will indicate types, sections, sections, and put down the required dimensions. Using plasma cutting makes it easier to achieve the desired result.

Several years ago, production conditions assumed the creation technological maps for the construction of future products. They were intended to effectively organize the work of specialists with manual milling machines. But, when automatic equipment appeared, it is no longer necessary to create such maps.

Detailed drawings in most cases support the electronic format from the very beginning and are created with its active use. Two-dimensional sketches, among other things, can be easily made by digitizing a paper drawing. Created in the program, such a picture will speed up the processing process.

Second phase

During the second stage, parts are created in a three-dimensional plane. This task is also carried out using a CAD environment. Thanks to this, visualization of the frame of parts, assemblies for assembly, and the entire product is available. An additional option is to perform calculations based on stiffness and strength.

The three-dimensional model, which has become the basis, is a mathematical copy of the product as it should be in finished form. To bring the project to life, all that remains is to produce a part that has the required characteristics. Using plasma cutting allows you to achieve results faster.

Third stage

It is to obtain the desired result that the third stage is used. It involves developing a route for future processing using plasma equipment. This type of work relates to the technological part of the process. It ultimately affects several parameters:

The quality with which the products are produced.
Cost level.
Processing speed.

If speak about milling machines with CNC, on which cutting is carried out, then in this case the three-dimensional sketch is transformed. This means the following actions are performed:

The processing area is limited.
Definition of transitions, finishing and roughing.
Selection of cutters with certain dimensions.
Programming the modes in which cutting is carried out.

There is special software - post-compressors. They allow you to export the data described above in a convenient format, which can be easily accepted by the controller for a CNC machine representing a particular model.

Fourth stage

The fourth stage ends with the design of a working control file that allows you to create the required part. After that, everything is done by the plasma cutters themselves.

Fifth stage

The work at the fifth stage is being completed. It assumes that the program file is loaded into the memory of the CNC machine. The processing itself is performed. The first sample of a released part must be checked. If errors are identified, adjustments are made to the electronic documentation.

Conclusion. Some features of plasma cutting

Plasma cutting is one of the most effective ways for metal processing. But such power is difficult to control; only highly qualified specialists can handle this. Only they can be allowed to control the plasma cutter.

Minor defects may appear on some parts, this is absolutely nothing to worry about. You just need to take into account the peculiarities of each of the bases used in production. Minimum size holes when using this technology also has its own characteristics. For example, if the diameter of the metal is 20 millimeters, then the maximum value for the hole itself is 15 millimeters. This must be taken into account when working with a CNC plasma program; the creation of a drawing will only be accurate in this case.

Depending on the thickness of the sheet, current with different characteristics must be used. For example, rolled sheets of 40 millimeters or more are cut with a current of 260 Amps. But 30 Amps will be enough if the thickness is only 2 millimeters. The current strength affects the thickness of the sheet. It is also necessary to take into account what shape the part retains in each section. The result also depends on this.

Modern equipment is different high level accuracy. But small deviations are perfectly acceptable as long as they do not exceed existing standards.

All photos from the article

Is it difficult to assemble a plywood laser cutting machine with your own hands? What problems can you expect? different stages implementation of the project? What equipment will you have to buy? In this article we will try to find answers to these questions.

Pros and cons of laser cutting

When implementing any large-scale project, the question of its feasibility always arises. We will try to help the reader answer it independently.

Benefits

In practice, a device for laser cutting of plywood is capable of working not only with plywood. The list of processed materials includes leather, fabrics, plexiglass, plastics, in short, all materials that have low thermal conductivity and a relatively low combustion temperature;
Thanks to CNC, the machine allows you to cut with the highest precision, creating detailed contours;
Its capabilities are not limited to sharp shooting. Laser machines for cutting plywood are quite capable of performing the functions of an engraver. By varying the speed of the carriage and the power of the beam, they can create complex images with tonal transitions;
Thanks to beam focusing, the cut width can be kept to a minimum- from 1/100 mm, which again has a positive effect on the accuracy of manufacturing parts or the detail of the image applied to the workpiece.

Problems

Of course, you can’t do without them either:

The price of the purchased equipment will not be cheap. The most popular solution for low-cost homemade engravers- a laser diode removed from a DVD burner is absolutely not suitable for cutting plywood due to low power. The minimum laser power for cutting plywood is 20 watts; with any significant thickness of the material, it is better to increase it to 40 - 80;

Information: a carbon dioxide laser tube of this power, when ordered directly from Chinese manufacturers, will cost the customer 15 - 20 thousand rubles at the current exchange rate. The cost of a complex and expensive focusing system, DSP controller, stepper motor driver and carriages will be added to the laser costs.

The life cycle of the tube is from 3 to 8 thousand hours, after which it requires replacement;
The laser requires liquid cooling. In industrial conditions, a cooling unit is used for this purpose, operating on the principle heat pump– chiller. The minimum cost of such a unit is 35 - 45 thousand rubles;

However: for a short duration of work, you can get by with a tank with a capacity of 80 - 100 liters and a water pump that will pump its contents through the tube jacket.

CNC implies the presence of not only special software, but also sketches of the outline of the product being manufactured. Blueprints for laser cutting plywood are not that easy to find; their independent construction will take a very long time;
Finally, the material is cut by rapidly heating and evaporating it. In this case, the edges of the cut inevitably become charred, and the room is filled with smoke. If so, you will have to design a closed case with a transparent lid and an intensive forced ventilation system.

Design

So how does it work homemade laser for cutting plywood?

The base of the frame is an aluminum corrugated pipe measuring 40x60, fastened with a furniture corner and metal screws. The body is assembled from inexpensive laminated chipboard - it does not experience significant loads during operation.

Please note: a 12-volt power supply is installed around the perimeter of the case. LED Strip Light. The backlight will allow you to visually control the cutting process.

Guides are fixed directly to the frame pipes, ensuring the movement of the carriages along the transverse axis.

Screwed to the carriages longitudinal pipe with another guide - this time under the carriage, which directly ensures the movement of the head.

And here is the laser head itself for cutting plywood. Foil is used to seal the connection between the tube and the fitting.

Modern computer technologies, if not completely eliminated the need to use manual labor, have definitely reduced it to a minimum. The use of laser machines is also gaining more and more fans every year.

Laser cutting of plywood "Wood"

Cutting wood with a laser machine

Wood is considered the most beautiful of all materials known to mankind. In addition, wood is environmentally friendly, safe and more quality material, which has been used since ancient times. It is used in various fields of production, in particular in construction. Today, a wide variety of products are made from wood, which we use both in everyday life and as decorative elements.

Not so long ago, every manipulation: cutting, engraving, burning, was carried out the old fashioned way - with your own hands. The process was, of course, labor-intensive, but very interesting and exciting. Today, any action with wood can be done using laser machines and improvised tools.

The laser has a thermal effect on wood. When cutting, the machine fuses the edge, thereby protecting the wood from germs and bacteria, providing more long term product service. Unlike metalworking tools, when working with the equipment, no waste, chips, sawdust is generated, the workpiece or model is not deformed, and the design is completely consistent with the original.

However, each type of wood is processed differently. It all depends on the breed, thickness, humidity, hardness, as well as the season of delivery.

Types of laser machines for plywood

Numerically controlled machines
Modern CNC laser machines can handle workpieces made from any wood perfectly. However, despite its versatility, each model has its own features and characteristics.

Floor machines
The working table of the machine can vary from 0.5 meters to 2 meters. Such machines are designed for installation in a specialized room and are used, as a rule, in heavy industries. The machines have a monolithic body, which provides them with stability of the entire structure, and also effectively reduces the vibration background that occurs during operation. The main purpose of such equipment is cutting, engraving, cutting wood.
Table machines
Small size layout that does not require installation production premises. Ideal for processing at home or within the walls of a small office. The excellent optical system allows you to cope with high-quality cutting and decoration of workpieces.
Compact machines
With your own hands, using a marker, you can apply decorative elements for various volumetric products (pens, key rings, jewelry, any layout, etc.), while each detail will be clearly visible, and the design will be durable. This feature is achieved due to the special design of the marker with a high-tech optical system.

Principle of operation

The layout, the workpiece is processed using a beam, which on the surface of the material looks like a spot, the diameter of which is several microns. The beam is formed thanks to a lens, which is installed at a short distance from the base part of the part.
The beam moves thanks to a drive that is pre-programmed to technical specifications element being processed.
Most often used in wood processing:

Gas, with a beam diameter of 10 microns, formed using a gas tube.
Solid state laser. The beam diameter of 1 micron is created using neodymium glass.

Advantages and disadvantages

Modern machines have many advantages:

High accuracy
Engraving or cutting using a machine is considered a highly precise process. The thickness of the cut is no more than 2 mm. To cut or engrave with your own hands, you no longer need to exert physical effort and use improvised tools.
High efficiency
The speed of work allows you to minimize the time when performing various volumes of work, which allows you to save energy resources.
Economical
This indicator applies to both material consumption and energy consumption indicators. Due to high precision of work, laser machines economically save wood, reducing waste to a minimum.
Versatility
In addition to cutting, the machines are capable of carrying out engraving work.

The main disadvantage can be attributed to only one factor - its cost and inaccessibility. Not every amateur will be able to afford to buy such an expensive laser wood processing machine, but everyone can try to make it with their own hands.

Approximate cost for laser cutting services. Prices are indicated in rubles per 1 linear meter cutting The engraving price is indicated in rubles per 1 square centimeter.

DIY laser machine

As mentioned above, not everyone can purchase laser-based woodworking equipment, but making it yourself from scrap materials is quite possible.

Tools and material for assembly

laser diode;
pencil, preferably mechanical;
radiator as a cooler;
optical fiber;
thermal lubricant;
D or 2 AA batteries;
eye protection.

The most important point in the work is eye protection. Under no circumstances should you look into the beam to avoid damaging your eyesight.

Regarding the diode... A high power IR diode with a 1W output, capable of burning any material except metal. The diode should operate at 2V with DC 1.7A. Please note that the diodes have different polarities (plus and minus). If the connection is incorrect, the diode will simply burn out.

Layout and its assembly

We connect the diode to the radiator. For better thermal conductivity, treat with thermal lubricant. Next we move on to the mechanical pencil. A pencil with a metal body is best suited, which will further avoid melting if overheated. We disassemble the pencil, insert an optical fiber into the tip and fix it using epoxy resin or glue.
