House made of plywood on a laser. Laser and milling cutting of wood and plywood

Plywood is one of optimal material decor. In addition to their performance qualities it is easy to process. However, mechanical figure cutting does not always give the desired result. Therefore, plywood laser cutting machines were developed. This is innovative technology, allowing you to make complex three-dimensional drawings and patterns.

Plywood laser cutting technology

Spot thermal effect for decorative natural material partially destroys it. This occurs due to the formation of plasma, similar to arc welding. However, the plywood does not melt, but burns out.

The main component of the machine is the laser installation. It generates concentrated radiation that affects the material. For this purpose, CO2 lasers are used. Semiconductor models do not have sufficient power and can only be used for artistic burning.

The procedure for performing shaped laser cutting of plywood.

Creating a drawing. Depending on the capabilities of the equipment, this can be done in in electronic format or apply a pattern to the surface yourself.
Selecting cutting mode. The determining parameter is the laser power. It depends on the thickness and structure of the plywood. If the degree of heating is exceeded, the width of the cut will increase.
Formation of the drawing. Its speed is affected by the laser power. The higher it is, the faster the process is performed. However, this increases the area of darkening at the edges.

This general description technology, which can be changed depending on the parameters and functionality equipment. The average laser power is about 20 W. It directly depends on the thickness of the plywood and the complexity of the pattern.

For work, it is best to use automated CNC wood processing centers. This will increase accuracy and improve productivity.

Features of cutting plywood with a laser

The main disadvantage of this type of equipment is its high price. A number of advantages that are not possible for machining, make laser wood centers very popular. They are used to complete production and are used to perform small amounts of work at home.

The defining advantage of laser cutting is the thin seam on the wood. It may be slightly larger than the beam diameter. This way, maximum detail is achieved and the result matches the original layout exactly.

This technology has the following features:

A slight darkening appears in the area affected by the beam. This is inevitable, but can be mitigated by painting or varnishing;
no mechanical effort is required for cutting. During the process, the surface deformation characteristic of classical methods processing;
The quality of work is affected by the composition of the wood. It is not recommended to use sheets made from coniferous species. They contain a large number of resins that, when evaporated, affect the appearance.

For large production volumes, it is necessary to provide a vapor extraction system. This is done using local ventilation. The absence of chips significantly softens the requirements for working conditions when cutting plywood to shape. laser machine.

The surface of the processed material is first cleaned of dust and dirt. The presence of varnish, paint or similar decorative and protective compounds is not allowed.

List of cutting equipment

To complete a professional production line, it is recommended to purchase specialized equipment. But in addition to the laser installation, it must contain other components.

To ensure maximum automation of work, the laser head must move freely along the length and width wooden surface. To do this, install a special carriage that moves along guides.

In addition to this for normal operation The following components are required:

electronic control unit. It controls the operation of the laser, gives commands for its movement relative to the sheet;
combustion products exhaust system. Despite their small number forced ventilation the concentration of harmful substances will quickly increase;
interface for entering information - drawing, machine operating modes, etc.

To perform a small amount of work, purchase expensive equipment will be inappropriate. The best option- use the services of specialized production companies. In this case, you only need to correctly draw up the design and select the material on which it will be applied.

In the video you can see an example of how the machine works to form a pattern on the surface of a plywood sheet:

Review of ready-made machine models

If you want to purchase a laser machine for cutting plywood, then pay attention to their difference in power:

desktop. Designed for work at home or in a small workshop with small workpieces. Power up to 80 W, price from 50,000 rubles;
professional. Used in small businesses in production designer jewelry, engraving, cutting materials to size. Power up to 195 W, price from 150,000 rubles;
industrial. Used on production lines high power And bandwidth with increased requirements for quality and accuracy of work. Power from 3000 W, price from 450,000 rubles.

Let's look at machines from different price categories.

The purpose of the article is to introduce brainiacs to working on CNC laser machine. Since I couldn’t find any articles on this topic, I decided that I would be the first to document the process :)

Step by step we will learn creating simple things which are useful in everyday life.

Step 1. Idea

How to find what to do? You relax, meditate and BAM! The idea comes to you to create something. You can already feel it in your hands, feel the weight, the roughness of the surface, the color. But it can also be completely banal - you need, for example, a hanger in your closet. That's what we'll do.
Well, of course, we are not looking for simple (banal purchase) ways. We need something unique. By the way, one more.

Step 2. Creation of a drawing/model, selection of materials

Everything is fine 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, they have not yet been able to do this. Are looking for finished drawing for remodeling or create your own from scratch. The easiest way is to find a vector drawing on the Internet and modify it. I used for this CorelDraw. The thickness of the outline depends on the material. Choosing an inexpensive one for a hanger plywood 8-10 mm.

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

Life hack: to avoid drawing hooks, the letters S were used :)

Step 3. Check dimensions, export

We check everything. We model the handling of the hanger, see that it fits normally on the crossbar in the closet and does not fall.

To avoid having to redo it, it’s better to check everything at once.

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

Step 4: Setting up the machine

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

Then the cutting parameters. 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 area Anyway! For each color of the lines, you can configure different power and type of operation. The screenshot shows the parameters CUT(cutting) for plywood 10 mm thick.

We have only 2 main parameters - passage speed and power. Yet again IMPORTANT not to cut on maximum power , This will extend the life of the laser.

Click Start.

Step 5: Painting

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

Working field size - 1550 x 2050 mm
Minimum order value - from 7000 rub. excluding material cost.
Cutting material - Customer's or own
File format - *cdr (CorelDraw); *.dxf, *.dwg (AutoCAD)

Material thickness, mm	up to 300 m	301 -500 m	501 - 1000 m	1001 - 3000 m	3001 - 10.000 m	more than 10,000 m
3	70	25.5	20	15.5	13	negotiable
4	84	31	24	20	17	negotiable
6	98	48	36.5	29.5	24	negotiable
8	126	63	48	39.5	34	negotiable
10	140	78.5	60.5	49	42	negotiable
12	168	94	74.5	59	50.4	negotiable
15	196	118	91	74.5	66	negotiable
18	224	154	106.5	91	81.5	negotiable
20	280	168	120.5	100.5	90	negotiable

The only thing better than laser cutting is hand carving on wood, but a hand-carved product will cost much more than one obtained after processing with a laser beam. Moreover, the production time for products using a laser will be much shorter compared to the long and painstaking process of cutting by hand.

Laser cutting considered one of the most effective ways impact on absolutely any materials. The high speed of impact and maximum accuracy of all cut lines attracts many customers. Products obtained by processing on a milling machine cannot be compared in quality to those created using laser cutting.

Laser cutting of plywood, the price and completion time of which can only delight, is a solution for many actual problem urgency of implementation. When a project is on fire, the only thing the right decision there will be an appeal to the laser machine.

Professionalism comes first

It is known that a laser can affect any surface, but each material has its own subtleties. Only a professional equipment adjuster will be able to select the optimal impact force and set the desired operating modes of the beam. There are frequent cases of damage source material due to the fault of an unqualified employee, therefore, to create products using laser cutting, you need to contact a trusted company that has good recommendations in the service market.

Process nuances

Laser cutting of plywood, in terms of efficiency, repeats cutting and, however, has a number of essential features and subtleties, as well as in business.

Plywood is considered the most capricious material for this type of processing, but carved wood products also look very elegant and beautiful. The fact is that different varieties wood requires different powers of the laser beam and, in addition, in solid plywood there are often knots that are much denser than the main layer; they can provoke the so-called “undercut”. Only an experienced specialist will be able to take into account all the nuances and minimize the risk of damage to expensive material.

When cutting plywood with a laser, the working surface may catch fire or the edge of the cut may become charred, which means it will darken. To avoid this, you need to constantly monitor the intensity of the cooling air supply. You can’t do this with just one automated process—you need the constant presence of an experienced installer.

All of the above difficulties determine the fact that laser cutting of plywood is the most complex method of processing the material.

Application of plywood products

The scope of application of cut plywood products is very wide, because wooden items have always been famous for their natural beauty. Products carved from wood are often used for interior decoration premises and landscape decoration of personal plots. Various panels, furniture elements, floor and wall decorations - wherever the designer's eye was directed, you can see plywood decor. Also, carved wood products are used as souvenirs: various stands, diplomas, frames, and so on.

Advantages over other methods of influence:

clarity and evenness of the cut, which will not need to be sanded after processing;
high cutting speed compared to other methods of influence;
the ability to obtain a wide variety of shapes and lines, the thickness of the resulting elements will be minimal;
Laser cutting of plywood, the price of which will please any customer, will allow you to create a product of any complexity, and its cost will not change.

Thickness above that indicated in the price list is discussed individually

Step 5: Painting

The edges of the products become charred in the air, so we need to sand them a little. Then we simply cover everything with clear varnish from a spray can or paint it.

Laser cutting of plywood as a business

The technology of cutting plywood using a laser makes it possible to obtain products that are very High Quality, modern CNC laser machines are capable of working 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 artistic cutting, in essence it promising business on laser cutting.

At the moment, the market for carved artistic products made of wood, including plywood, is practically empty, because laser cutting machines began to be used in production quite recently, and even then only a few; in most cases, carpentry shops operate on outdated equipment.

An example of a product laser cut from plywood.

Laser cutting of plywood: operating principle.

Without delving into terminology and saying in simple words, in laser machines the function cutting tool performs a laser, which consists of glass tube filled with gases (Nitrogen, Helium, Carbon Monoxide), under the influence electric charge radiation is created in the tube, which, passing through a system of mirrors, creates a powerful beam of light capable of intensely heating the treated area (in in this case plywood) as a result of which the wood fibers instantly burn out. This is how laser carving occurs. various materials, while the cutting thickness is no more than 0.02 mm, which allows you to cut products with high precision.

But the laser cutting method has its advantages and disadvantages.

Advantages:

Precise processing of small parts.
Smooth edge when processing.
Sufficiently high cutting speed.

Flaws:

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

Laser machine for cutting plywood.

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

Laser cutting machines vary in power, productivity and the range of operations performed; depending on the configuration, they can perform functions such as engraving, milling, and cutting.

How does a laser cutting machine work?

CNC machines already have support for programs: CorelDraw, AutoCad, Adobe Illustrator; to work, you just need to connect the machine to your computer and install the drivers. You need to create a pattern in a graphics editor or process an already scanned image.

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

The video shows the machine in operation.

Laser cutting: what can you do?

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

An example of a cut out artistic composition made of plywood.

These can be decorative items, artistic cutting, patterns, stained glass windows, picture and photo frames, elements of furniture and household items, souvenirs, refrigerator magnets, collapsible designs of ship and airplane models, construction toys for children, signs, photos on wood, lampshades for bedside lamps and table lamps, napkin holders, cutting boards for kitchen, menu, etc.

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

Laser cutting of plywood as a business.

How much does laser cutting cost? The cost depends on the linear footage of the cut and the thickness of the material, the average cost is $0.50 per linear 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 a laser machine you get almost unlimited possibilities for cutting and engraving wood products. If you establish markets for products and find regular customers for artistic cutting then you can count on significant profits from laser cutting.

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

After purchase laser engraver experimented a lot. And I burned and cut, tried different programs. But it just wasn’t possible to cut the plywood. WITH wooden blanks the same thickness there were no problems. But the plywood didn’t work. I thought that the reason was in the glue that glues the plywood together and gave up further experiments until one of my subscribers shared the link with me. http://mysku.ru/blog/china-stores/48299.html

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

And today we will take a previously prepared vector drawing and 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 passes and export the picture to plt format. Then go to the site: https://sites.google.com/site/nikromsoft/home

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

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

After this we can fire the laser and burn through the plywood. Here is the result.
