Openwork plywood cutting. Do-it-yourself laser cutting of wood. Laser cutting process

Which is carried out on special laser and milling equipment. Sawing plywood is very often required when using large format plywood sheets is not very convenient, or when it is necessary to perform curly cutting material in large quantities.

Prices for laser cutting plywood

Plywood is made from sheets of veneer glued together. special glue on a resin base, which, when cutting plywood, is very dull and wears out cutter knives and other tool elements. In this regard, it is very important to use tools made of very strong, hard alloys for cutting plywood. good quality. Only in this case, plywood will lend itself well to cutting and processing, and the tool will not wear out and keep its performance longer.

Cutting plywood with a laser

laser cutting is the most modern and popular method of processing, sawing and decorating plywood. Laser cutting allows not only to cut plywood into pieces in a short period of time, but also to create high-quality drawings.

Modern laser devices cut any plywood sheets with sufficient quality and make it possible to manufacture various elements from them without exerting a mechanical effect on them. This cutting method eliminates the formation of chips or pile on the edge of the processed material. However, very often the result of laser cutting depends on the quality and type of raw materials from which the plywood sheet is made, as well as on the method of its processing and the type of glue used in its manufacture.

The cut of the material after laser processing burns, slightly changing its color, which can be both a positive and a negative feature of this type of cutting. The darkened edge of the plywood, formed after cutting, emphasizes the contours of the material, which can be used for decorative purposes.

Milling cutting of plywood allows you to perform figured cutting or high-quality cut material in a straight line. At the same time, the plywood in the place of the cut does not change its color.

Milling cutting allows you to perform both through cutting of plywood and surface cutting, when the cutter penetrates the material only to a predetermined depth. Milling plant also allows you to mill technological recesses, grooves and perform many other various operations.

Milling cutting of plywood involves a mechanical effect on the material, but despite this, due to the use of specialized cutters, this method of cutting plywood allows you to almost completely eliminate the formation of chips and pile on the cut of the material.

CNC milling woodworking machines allow for accurate, reliable and fast cutting of plywood according to pre-programmed parameters. With the help of a milling machine, you can not only cut plywood and perform its figured cutting of the required configuration and size, but also perform final processing of the edges of the material to remove various roughness, creases and irregularities from them. Also using milling cutting can be done decorative trim in the form of relief engraving or figured cutting, which is often used when decorative design furniture.

Cutting plywood at home can be done using a manual or electric jigsaw for cutting sheet materials. This method of cutting does not allow to achieve a sufficiently high quality of the cut, since after cutting there may be chips on the edges of the plywood, and the cut itself may have irregularities.

The manual way of cutting plywood is the most simple and accessible way. To cut plywood at home, you can use a regular hand saw. Since plywood is a fairly dense and durable material, cutting it with a hacksaw requires a certain amount of physical effort. The thicker the plywood, the harder it will be to cut. That's why manual way cutting is generally used for relatively thin plywood and for cutting predominantly along a straight path.

Except hand saw for cutting plywood at home, you can also use a disc electric saw. Using a saw, you can easily cut plywood of any thickness. However, this method is also mainly suitable for cutting plywood in a straight line. Also, the disadvantage of this method is the formation on the surface of the cut material a large number chips.

Laser cutting is far from new method artistic processing wood, which from the moment of its appearance immediately gained immense popularity. Compared to a similar process performed manually with a jigsaw, this method demonstrates a number of advantages, the main of which is the speed of work with its high accuracy, provided by modern multifunctional equipment.

Also, laser cutting and engraving of plywood makes it possible to achieve a unique pattern that is distinguished by aesthetic appeal and beauty, while the cost of the service provided by a professional craftsman using expensive equipment is affordable for most customers. Minimum Width the cut here does not exceed 0.01 mm, which is practically impossible when processing wood with a hand tool.

An example of cutting plywood with a laser:

Laser cutting technology implies a directed action of a laser beam on plywood, which makes it possible to form a cut of varying complexity and configuration. This method is non-contact and consists in raising the temperature at the point of contact of the beam with the tree, after which the material is removed by evaporation.

The use of equipment, which in this case is a laser machine, guarantees perfectly even edges after processing, which is very important when cutting artistic elements and complex openwork patterns. Here, wood dust and shavings are completely absent, which give the carpenter a lot of inconvenience. In the process of cutting wood with a laser under the influence of high temperatures In places of cut, plywood usually darkens, which can be regarded both as advantages and disadvantages of the method, it all depends on the artistic vision of the master. If necessary, this feature can be eliminated by supplying laser machines with a ventilation and blowing system that removes combustion products.

The principle of operation of the laser beam

To obtain a laser beam, it is necessary to use a tube of gas and a mixture of helium, nitrogen, and carbon dioxide. When voltage is applied, monochromatic radiation of directional action is activated, carried out with the help of technological mirrors. Experienced craftsmen they cut wood with devices whose power starts at 20 watts, but amateurs at home often use less powerful equipment. As mentioned earlier, the accuracy of laser cutting wood is very high, and the given pattern turns out to be almost jewelry.

To achieve smooth and clear edges of the pattern according to the specified parameters without the application manual labor, it is enough to install the corresponding program . The minimum size of the laser beam in combination with numerical programs allows the process of cutting plywood with a laser in a matter of minutes. Modern machines equipped with CNC require the master only to draw up a sketch, while wood cutting itself is performed quickly and simply in automatic mode.

Additional accessories

According to the type of configuration, the equipment on which laser cutting of non-metals is carried out can be divided into units with and without numerical control programs. There are also additional devices that optimize the cutting, processing and manufacturing of parts. Devices that expand the functionality of laser machines are:

• chillers that adjust the process of cooling the glass laser tube through which the gas mixture is supplied. To ensure optimal temperature regime, the tube is closed with a kind of shell through which the coolant circulates, and the device itself consists of a water pump, water and freon;
• blowing systems that remove combustion products, so that the plywood does not darken in places of contact with the beam, and the products acquire an attractive appearance.

Please note that laser cutting of MDF or any other wood material requires continuous cooling of the focusing lens, but such a system is not additional option and is necessarily present on all types of machines without exception. The cost of professional chillers, which were discussed above, is quite high and starts at $ 500.

Often, home craftsmen make a cooling system on their own, using a pump for pumping water. Thanks to this technique, laser cutting of veneer, plywood, MDF or chipboard will be available without unnecessary financial expenses. By the way, a standard non-metal cutting job can require over a hundred liters of water. If possible, it is advisable to replace the water with freon more suitable for such purposes, which will be much more efficient.

Laser cutting process

Quality production decorative elements where laser cutting of MDF is used or other wood materials are used, it is impossible without modern equipment to which a high quality requirement is imposed. The process itself cannot be called simple, because it requires attention and artistic talent when creating sketches. No less stringent requirement is put forward to the treated surfaces. Plywood should not contain any flaws in the form of cracks, chips and other flaws, otherwise the result may be deplorable, and the master will make his efforts in vain.

Cutting veneer with a laser, as well as processing any wood using a point light beam, can be carried out both manually and automatically. Despite the fact that in this case the surrounding space is not polluted by chips and wood dust, some inconveniences are still present. The thing is that such production is associated with a heating process, due to which the cutting laser ray burns wood and, as a result, emits smoke. That is why it is impossible to allow acrid smoke to fill the room, be sure to provide an exhaust system. Also, laser cutting of plywood can provoke minor fires, and in order to avoid a fire, it is better to place a container of water nearby in advance, which will come to the rescue in case of an unforeseen circumstance.

Materials, products and prices

The laser cutting method is specially designed for processing plywood, and indeed any wood, in order to give it decorative effect. For example, laser cutting of MDF can turn an ordinary unsightly workpiece into a masterpiece of carpentry. In addition to the manufacture of interior elements, this technique allows processing wood in the production of souvenirs and gift products. There are a huge number of products, the main material of which is inexpensive plywood, however high level The quality of laser processing modifies the primitive workpiece so much that it looks like a precious exclusive thing. The most popular items in this category of goods include all kinds of coasters, panels, frames for photos and paintings, caskets, vases, etc.

Having a laser machine in his arsenal, the master will be able to regularly afford to create unique original gizmos for sale or for personal use, but what about those who do not have special equipment or lack the necessary skills? The answer is obvious. Cutting wood with a laser can be done in hundreds of workshops that work according to the sketches of the customer, you just need to voice your wishes. Such a service is quite affordable, and on average its cost is 30 rubles per linear meter with a material thickness of 5 mm.

Table: Prices for laser cutting services provided

The price fluctuation in one direction or another is directly affected by the thickness of the wood, the molding and the complexity of the pattern.

The purpose of the article is to acquaint brainmen with working on a CNC laser machine. Since I did not find any articles on this topic, I decided that I would be the first to document the process 🙂

Step by step, we will learn how to create simple things that are useful in everyday life.

Step 1 Idea

How to find what to do? You relax, meditate and BAM! You get the idea to create something. You already feel it in your hands, feel the weight, surface roughness, color. But it can also be quite banal - you need, for example, a hanger in a closet. We will do it. Well, of course, we are not looking for simple (banal purchase) ways. We need something unique. By the way, another idea to quickly put on hangers.

Step 2. Drawing/model creation, material selection

Everything is in order in your head ... I mean your craft. Now we need to somehow convey this to the computer. They have been able to read, write, and speak for a long time, but as far as the transmission of thoughts and images is concerned, this is not yet the case. Are looking for finished drawing for rework or create your own from scratch. The easiest way is to find a vector drawing on the Internet and modify it. I used CorelDraw for this. The thickness of the contour depends on the material. We choose inexpensive plywood 8-10 mm for hangers.

Let's add a few more hooks and arrange it all tighter. There are special additions for arranging objects on a sheet, but about them in the following articles.

Life hack: in order not to draw hooks, the letters S were used 🙂

Step 3. Dimension check, export

We check everything. We simulate the handling of the hanger, we look at what would normally be worn on the crossbar in the closet and not fall.

In order not to have to redo it is better to check everything at once.

We save our drawing in dxf format (the most optimal for us).

Step 4. Setting up the machine

Click Import... select the units of measurement millimeters. Let's check the dimensions again. If everything is good, they should increase slightly (by hundredths of a millimeter - this is to take into account what the laser will “eat”).

Then cutting options. There is a table with the names of materials and cutting parameters, but as practice has shown, it is necessary to carry out test cutting on small plot Anyway! Each line color can be customized different power and type of work. The screenshot shows the CUT (cutting) parameters for 10 mm plywood.

We have only 2 main parameters - passage speed and power. Again, it is IMPORTANT not to cut on maximum power, this will prolong the life of the laser.

Step 5. Painting

The edges of products in the air are charred, so we need to process them a little sandpaper. Then just cover everything with a colorless varnish from a spray can or paint.

Ready!

All good beaver!

Laser cutting plywood as a business

The technology of cutting plywood with a laser allows you to get products of very high quality, modern CNC laser machines are able to work with materials such as chipboard, plywood, wood, glass, stone, leather, etc. Laser cutting machines allow you to organize the production of a wide variety of products with an artistic sharp, in fact it is a promising business in laser cutting.

On this moment the market for carved art products from wood, including plywood, is practically empty, because laser cutting machines have been used in production quite recently, and even then only a few, in most cases, carpentry shops work on outdated equipment.

An example of a product cut by a laser from plywood.

Laser cutting of plywood: the principle of operation.

If you do not delve into the terminology and speak in simple words, in laser machines the function cutting tool performs a laser, which consists of a glass tube filled with gases (nitrogen, helium, carbon monoxide), under the influence of electric charge radiation is created in the tube, which, passing through a system of mirrors, creates a powerful beam of light capable of intensively heating the treated area (in this case, plywood), as a result of which the wood fibers instantly burn out. This is how laser cutting works. various materials, while the cutting thickness is no more than 0.02 mm, which allows you to cut products with high accuracy.

But, laser method cutting has its advantages and disadvantages.

Advantages:

• Precise processing small parts.
• Smooth edge when processed.
• Relatively high cutting speed.

Flaws:

• After laser processing, the edges of the product remain burnt dark brown.

Laser cutting machine for plywood.

The laser cutting machine consists of a working surface, over which it moves laser cutter. The machines use numerical control, the carriage with the laser moves with the help of stepper motors along two perpendicular guides, axes "X" and "Y". By using software the coordinates for moving the carriage with the laser are set.

Laser cutting machines differ in power, performance and a set of operations performed, depending on the configuration, they can perform such functions as engraving, milling, cutting.

How a laser cutting machine works.

CNC machines already support programs: CorelDraw, AutoCad, Adobe Illustrator, to work it is enough to connect the machine to a computer and install drivers. You need to create a pattern in a graphics editor or process an already scanned image.

On work surface The workpiece for processing, for example, a sheet of plywood, is placed and fixed on the machine, the machine is set up, parameters such as the intensity and speed of the laser passage are indicated.

The video shows the machine in operation.

Laser cutting: what can be done?

On laser machines, you can set up the production of various products, cut and engrave souvenirs from plywood, boards, MDF.

An example of a carved plywood art composition.

These can be decor items, artistic cutting, patterns, stained-glass windows, picture and photo frames, furniture and household items, souvenirs, fridge magnets, collapsible designs of ship and aircraft models, constructor toys for children, plates, photos on wood, lampshades for nightlights and table lamps, napkin holders, cutting boards for kitchen, menu, etc.

The video shows how the box is engraved and cut out on the machine.

Laser cutting plywood as a business.

How much does laser cutting cost? The cost depends on the length of the cut and the thickness of the material, the average cost is $ 0.50 per running meter cut. The length of the cut can be calculated directly in the figure using the program.

The business is quite promising, in fact, with laser machine you get almost unlimited possibilities for cutting and engraving wood products. If you establish markets for products, and find regular customers on artistic cutting then you can count on a significant profit from laser cutting.

Cutting plywood with a Chinese laser. Creating a G-code for laser cutting.

After acquisition laser engraver experimented a lot. And burned and cut, tried various programs. But that's just cutting plywood did not work. There were no problems with wooden blanks of the same thickness. And the plywood didn't work. I thought that the reason was the glue that sticks the plywood together and refused further experiments until one of my subscribers shared a link with me. http://mysku.ru/blog/china-stores/48299.html

The article told how with a laser of the same power as mine, 5.5 W, the author cut plywood and made various crafts. Having carefully studied everything, I decided to resume the tests. But with minor amendments.

And today we, having taken a pre-prepared vector drawing, will try to burn it out.

You can download this picture here: https://drive.google.com/drive/folders/0B6x0JsiBUva0amNTSzhxcFNNa0E?usp=sharing

Following the instructions from the video, we overlay the picture as many times as we need and export the picture to plt format. Then go to the site: https://sites.google.com/site/nikromsoft/home

And download the HPGL2CNC program, with its help we will convert our file into a G-code. The settings should be the same as in the screenshot.

Having received the file in nc format, we can open it in the Grbl Controller program. We set the settings as follows:

After that, we can start the laser and burn through the plywood. Here is the result.

Good luck with your crafts.

Although materials created from wood fiber are always different affordable price, questions economical consumption always remain up to date. Conventional mechanical processing methods wood materials are accompanied by a huge amount of waste, the mass of which can even exceed the volume of the finished product. The use of a progressive tool, which is a laser beam, made it possible to solve this problem. In addition, the focused light output provides a degree of precision that is not available with mechanical processing methods. Laser cutting of plywood, by virtue of the peculiarities of the technique itself, offers an extremely high speed of operations. In fact, all operations within a particular workpiece are performed during one sheet setup and require minimal operator involvement after starting the CNC machining program.

With a professional approach to the organization of work, even despite the rather high cost of operating the equipment, the implementation of structures and samples of the most complex shapes remains much more convenient and affordable for our customers. The price for laser cutting of plywood, as well as for other materials, is formed mainly by the thickness of the workpiece and the total length of the contours of the parts. With a professional approach to the design of the template, the selection of the type and nature of the impact, it is possible to successfully avoid any additional costs.

We carefully monitor modern materials and determine the possibilities and features of their processing, so our company always takes the most professional and rational approach. The price of MDF laser cutting remains affordable for both small and large-scale orders, so cooperation with us is extremely profitable and convenient.

Videos about our work

Plywood is a versatile material, which, due to its shape stability, is often used in the manufacture of furniture and other home and apartment decoration items. Plywood is made by gluing individual layers of treated veneer together. Plywood is very light and strong, also environmentally friendly, which gives it special advantages.

Cutting principle

For precise processing of this material, professionals use laser cutting of plywood. With this type of processing, patterns and different patterns can be applied to this material. The process in question is advanced technology, and helps to create the most bizarre and original forms products. Even the most daring and bizarre ideas of designers will be executed quickly, beautifully and, most importantly, gracefully. This design option looks great in do-it-yourself kitchens.

Variety of patterns and figures

It should be noted that laser cutting plywood is not a simple task, as it might seem at first glance. The material may exhibit various errors such as different size glued layers, missed and not glued places, resin smudges and other errors. Therefore, you need to approach this issue seriously and professionally.

Previously, such equipment had a significantly expensive price, in connection with this, it was necessary to create devices with the help of which laser cutting of plywood was carried out with their own hands. Such craftsmen have been doing this for a long time and very professionally.

The material is cut electrically or manual machine. The laser emits point beams of light without touching the treated plane. This cutting method eliminates the appearance of waste in the form of small chips or dust, this is another plus.

These craftsmen carry out work with the help of homemade device made from a matchbox and a DVD drive. This device allows you to produce a directed thermal effect on wooden surface, burning through the material through (acts on a thickness of 0.01-0.02 mm). Such a manipulation is suitable for the manufacture of small and decorative details, for example, for decorating a dressing room made by oneself. The burning method leaves marks along the edges of the processed material, which can be critical.

DIY cutting

Do-it-yourself laser cutting of plywood is carried out using a gas tube (nitrogen-helium-carbon monoxide is used). The power of directed gas is from 20 watts. An electric spark is applied to the tube, which provokes the appearance of monochrome radiation, reflecting from the built-in mirrors, it ultimately affects the plywood.

Cooling occurs by constant circulation of cold liquid in an additional layer of tube. You can make such a cooling device with your own hands from a 80-100 l tank and a pump. Freon is the most common cooling liquid. To ensure trouble-free operation, it is necessary to install a good transformer. An extractor hood will help eliminate smoke and fumes.

Laser cutting machine

Professional cutting

If professional one-time work is necessary, then it is inappropriate to perform the above complex maneuvers. It is enough to contact the firms for laser cutting of plywood and other materials. Such companies have a ready-made and high-quality machine, laser cutting of plywood on which will be done quickly and professionally.

Firms involved in processing such as laser cutting plywood, the price of work is set depending on the thickness of the material. The ornateness of the patterns that you order plays almost no role in determining the price.

The best brand of raw materials for working with a laser is the FK brand. As an adhesive base for these plywood sheets carbamide resin is used. Such a resin has lower heat resistance than phenolic resin and bakelite varnish often used in the production of sheets. The resistance of the adhesive base to the laser action is reduced, which reduces the power consumption of the machine and speeds up the work process.

By following all the instructions that professionals will provide you, you can do exactly what you have in mind. The product will delight the eye with the elegance of execution and the accuracy of even the smallest details.
