Elements affecting laser engraving

Elements affecting laser engraving

The 4 most important elements that affect laser engraving are:
Engraving speed, laser power, engraving accuracy, material.

A specific material needs to absorb a certain amount of laser energy to achieve a certain effect. The absorbed energy is laser energy = laser power / engraving speed. Therefore, to increase the laser energy absorbed by the material, one is to increase the laser power; two, to reduce the engraving speed, which method is used depends on the material and the final engraving effect. Average users avoid speeding up because that reduces productivity.

In addition to speed, the engraving accuracy also has a very big impact on the effect. The use of 500dpi from the practical experience with 600dpi precision carved items with the naked eye can't see much difference, general users will use 500dpi to complete most of the work only in the cutting or when you need a high energy density will use 600dpi or higher settings, so decided to impact on the final effect of the sculpture I'm afraid carving material. New users may not know much about the characteristics of materials, nor do they have a deep understanding of the engraving forms of different materials. Here are some of the commonly used carving materials and carving methods of presentation.

In addition to speed, the engraving accuracy also has a very big impact on the effect. The use of 500dpi from the practical experience with 600dpi precision carved items with the naked eye can't see much difference, general users will use 500dpi to complete most of the work only in the cutting or when you need a high energy density will use 600dpi or higher settings, so decided to impact on the final effect of the sculpture I'm afraid carving material. New users may not know much about the characteristics of materials, nor do they have a deep understanding of the engraving forms of different materials. Here are some of the commonly used carving materials and carving methods of presentation.

First, the gray performance
Laser engraving is a method of engraving, with a natural advantage in the performance of grayscale. Therefore in the design can be used as carving gray forms, it has two advantages, one is to reduce the coloring process, saving the cost; two is to enrich the carving performance means, increase the sense of hierarchy graph. Users in use, first in the graphics to do different gray filling, engraving output, select black and white mode, you can try different dot effect, the accuracy is generally not more than 500dpi.

Two. Engraving materials
1, wood
A, logs (unprocessed wood). Wood is the most commonly used laser material. It is easy to engrave and cut. Light colored wood, such as birch, cherry, or maple, can be well blown by lasers and therefore more suitable for carving. Each kind of wood has the characteristics of being, some tight some, such as hardwood, will use more power in the laser engraving or cutting.
B plywood. It doesn't make much difference with wood. Just pay attention to the depth of engraving. The cut back edge will also blacken like wood.

2 density board

A, ordinary density panel. This is what we commonly used in MDF pallets that make signs lining, and black uneven carved pattern color, usually colored.
B, laser special density panel. Some density boards are specially designed for laser engraving. The carved patterns are uniform in color and good in color without staining.
C, clean, after carving, you can use a damp cloth to clean the surface of the mdf.

3, acrylic

A, acrylic. Acrylic is second only to wood, the most commonly used engraving materials, it is easy to be cut and carved, there are a variety of shapes and sizes, relatively speaking, lower cost. There are two kinds of organic glass production process: Casting and rolling, laser engraving mainly by casting organic glass production, because of the frost effect it produces after the laser engraving is very white, a sharp contrast with the original transparent texture, and organic glass rolling produced after the laser engraving is transparent, no a sufficient contrast. It is recommended to buy a product of high purity, or else the possibility of melting when the material is bought or carved or cut.

B, engraving
Under normal circumstances, the use of organic glass back carving, that is, from the front carved, followed by watching, which makes the finished product more three-dimensional. In the back carving, please mirror the image first, and the engraving speed is fast, the power is low. Such as engraving power is too high, the bottom will appear uneven stripes, such as hope to carve deeper, try to carve more than a few times.

C, clean
Acrylic pigments may be used, and other pigments may damage the finish of acrylics.

Improve the efficiency of laser cutting machine

Improve the efficiency of laser cutting machine 

Laser cutting machine is mainly using laser beam to the plate surface and release energy to see steel melting and evaporation, because energy is highly concentrated can rapid local heating to melt and vaporize steel plate, because the energy is concentrated, just only a small amount of steel reached other parts, basic not caused any deformation, using laser can produce complex shape of the workpiece, the cutting of the workpiece, the does not need for the next step processing can be used directly.
Laser cutting machine has three advantages: good cutting quality, fast processing speed, clean, safe, no pollution, in the production of laser cutting machine power is certain, so I want to improve efficiency, it is necessary to adjust operation.

1 The learning and manipulation of new machines           

In the process of operation, the operator needs to strengthen the learning and skills of the machine performance through the daily production. To will work on an alternative practice, spare time to strengthen the machine in all aspects of knowledge learning, do meet machine appear small problem can be solved, the problem appeared to know where the problem lies, and help solve the problem.

2 Know how to modify the CNC cutting procedures           

For CNC laser cutting machine, make changes to the program, using linear surgical method, will drive up to the point on the arc, the cutting down of circular cross section is very smooth, to ensure that the quality of the parts.

3 Optimize the scheduling scheme           

Through consultation and the fish Technology Department of the workshop, the two beam sharing a common edge cutting, this does not affect to the cutting effect, so the efficiency is to artificially raise.

Effect of laser output power on laser cutting

Effect of laser output power on laser cutting 
When using laser cutting machine,the laser output power is a parameter that has a direct relation with the melting ability of the processed. For getting good effect of cutting,we need increase the output power in order to improve the processing ability.

Improve processing capacity:
1, improve the laser cutting speed.          
2, increase the thickness of the processing plate.          
3, processing of aluminum, copper and other high reflection spectral reflectance factor.          
4, zoom lens from the short focal length lens.          
5, the focus of the location from the surface of the processed material changes.

We can determine whether the use of the processing conditions of the output energy is appropriate, according to the processing of the cutting surface and machining in the case of the spark. When the output power is much larger than the standard value, the thermal effect of the incision increases, and the melting loss occurs at the corner. And cut the noodles to become thick, from the upper to the lower part of the vertical.
If the output power value is far less than the standard value, the lower part of the cut is significantly thicker, become the state of digging into. And with the increase of the amount of adhesion of slag, it is difficult to remove. Mars is lagging in the cutting process in the opposite direction in the cutting process.
Suitable for the processing of the output conditions exist within a certain range, the thinner the thickness of the processing board, the wider the range of output conditions. Output processing in proper conditions, the cutting surface streak fine, lower relative to the speed of light slow.

Common problems and treatment methods in laser cutting

Common problems and treatment methods in laser cutting

1.Any kind of thermal cutting technology, in addition to a small number of cases can be from the edge of the board, the general must wear a small hole in the board. Before the laser punching compound machine with a hole punch out first, and then again from the hole at the beginning of laser cutting. Basic method for two kinds of perforation of laser cutting machine without punching device:

Blasting perforation
After the material is irradiated by a continuous laser, a concave hole is formed in the center, and the oxygen flow from the laser beam is quickly removed to form a hole. And sheet thickness is related to the size of the hole and blasting perforation average diameter is half of the plate thickness, so for thick plate blasting perforation diameter larger diameter, should not require higher in precision machining parts, can only be used for waste. In addition, due to the use of oxygen pressure and cutting the same, the splash is larger.

Pulse perforation
Pulsed laser with high peak value is used for melting or vaporization of a small amount of material, air or nitrogen is used as an auxiliary gas to reduce the expansion of the pores due to heat release and the gas pressure is less than the oxygen pressure during the cutting process.
Each pulse laser produced only a small particle injection, and gradually deepened, so thick plate perforation time takes a few seconds. Once the perforation is completed, the auxiliary gas is changed to oxygen for cutting. The perforation diameter is smaller and the perforation quality is better than that of the blasting hole. The laser used in this system should not only have high output power, but also more important is the time and spatial characteristics of the beam, so the general cross flow CO2 laser can not meet the requirements of laser cutting. In addition, a more reliable pneumatic control system is needed in order to realize the gas type, gas pressure switch and perforation time control.In the case of using pulse perforation, in order to obtain high quality cut, from the workpiece at rest, the pulse perforation to the workpiece constant velocity continuous cutting transition technology should be paid attention to. Theoretically, it is usually possible to change the cutting conditions of the accelerating section, such as the focal length, the position of the nozzle and the gas pressure, but in fact, the possibility of the above conditions is not very much due to the time is too short. In the process of industrial production, the method of changing the average power of laser is used to compare the reality, the specific method is to change the pulse width, change the pulse frequency, and change the pulse width and frequency.

2. cutting holes (diameter and thickness) analysis of deformation
This is because the machine (only for high power laser cutting machine) in machining holes not take the blasting perforation, but with pulse perforation (soft puncture), which makes the laser energy in a very small area is too concentrated, non machining area was burned, cause deformation of the hole, the processing quality is affected. Then we should be in the process, pulse perforation (soft puncture) to blasting perforation (ordinary puncture) way to solve. For small power laser cutting machine is just the opposite, in machining should adopt way pulse perforation to achieve better surface finish.

3.when the laser cutting of low carbon steel, the solution to the work of burr
According to the working principle and design of CO2 laser cutting, and analysis the following reason is caused by machining burrs in the main reason: the laser focus on the position is not correct, need to be adjusted according to the focus position test, offset focus; the laser output power is not enough, need to check the laser generator is normal or not, if the normal, is to observe the effect of laser numerical control output button is correct, adjust the line; the cutting speed is too slow, the need to increase the line speed in operation control; the purity of cutting gas is not enough, need to provide high quality gas cutting work; laser focal shift, need to be adjusted according to the focus position test, offset the focus of the machine running time is too long; the stability, the need to shutdown and restart.

4.Laser cutting of stainless steel and aluminum plated zinc plate, analysis of the causes of burr formation.
The factors above, first consider the low carbon steel cutting burr, but not simply accelerate cutting speed, because increased speed sometimes sheet cutting not to wear, this kind of situation in processing aluminized zinc plate is particularly prominent. At this time should be integrated into other factors to consider the machine to solve, such as whether the nozzle to replace, rail movement is not stable, etc..

5.Analysis of laser machine can not cut through
Analysis revealed that several of the following is instable processing of: laser head nozzle selection and processing board does not match the thickness; laser cutting line speed is too fast, need to operate the control lines are reduced speed; in addition, also need to pay special attention to, in the laser cutting machine cutting more than 5mm carbon steel needs to be replaced laser lens focal length of 7.5 ".

6.Method for solving non normal spark in cutting low carbon steel
This situation will affect the cutting section of the parts finish machining quality. At this time, in the case of other parameters are normal, should consider the following: laser head nozzle loss, should be promptly replace the nozzle. In the case of no new nozzle replacement, the cutting work gas pressure should be increased; the nozzle and the laser head are connected at the screw thread. At this point should be immediately suspended cutting, check the laser head connection status, re good thread.

7.Selection of puncture point in laser cutting
Laser cutting the working principle of the laser beam is: in the process, material after the irradiation of laser in the center of the formation a pit, and then by the work flow and laser beam coaxial soon will be molten material removal of the formation of a hole. This hole is similar to line cutting of the thread hole, laser beam on this hole for the processing of opening and starting point of contour cutting, usually under flight light path laser beam walk line direction and the parts to be machined vertically cutting contour tangent direction. Therefore, laser beam in began to penetrate the plate into the cutting contour parts of this period of time, the cutting speed in vector direction will have a great change, namely the direction vector of 90 degrees rotation by vertical to the cutting contour tangent direction turn and cutting contour tangent coincidence, and contour tangent angle is 0 degrees. In this way, the cutting surface of the processed material is relatively rough cut surface, which is mainly in the short time, the laser beam in the direction of the movement of the vector is very fast. Therefore, in the use of laser cutting parts, we should pay attention to this aspect of the situation. , in the design of components of surface cutting fracture no roughness can not to do manual processing in laser cutting programming, to control the software automatically generates the puncture point; however, when design of machining cutting section has higher roughness requirements, note to this problem, usually in series laser cutting program of laser beam starting position be manually adjusted, namely artificial for the puncture point of control. The need to produce the original laser puncture point program moved to the reasonable position of need, to reach the surface precision requirements of the processing parts.
