CNC woodworking machine carving effect and Tools selection

CNC woodworking machine carving effect and Tools selection                                                             

Select CNC wood carving machine, tools very important, only choose a good tool to make CNC woodworking engraving machine finer work. Because wood engraving machine at work, the processing of sheet material, tool path, etc. are not the same way,so to be more different carving styles.

Flat, Sharp end of engraving, Contour cutting are the three most common carving effect, there is a round sculpture is also highly popular.

The round carving effect is similar to relief carving, is widely used in advertising Words, field signs, carved furniture, metal molds, printing (making blanching mold), plastic model making. Round carving is generated by the cross-sectional shape defined method for 3D surface machining path, showing round effects, mainly for the round arc of text or graphics and other art forms design.

When using this function needs to set some parameters: edge width, depth, width, angle, corner, etc. After setting up, choose the right tool to generate toolpath, then you can use the engraving wood CNC machine processing  . Round machining operations simplely, but it may also be generated embossed effect.

CNC Tools selection

CNC Router machine performance itself is important, but the tool of choice also affects the processing results and processing efficiency.

Performance and quality of tools directly affect the smooth processing of the requirements of a qualified product, the tool can meet the requirements of high-speed cutting, the tools life, as well as the level of ATC frequency directly affect production line starting rate, affecting cycle time and productivity a product may be used in the production of several tools, the processes of production directly affects the next process of production.

In order to improve production efficiency and reduce production costs, the use of modular tools and the resulting non-standard tool, thus a key tool in particular non-standard tools, such as not timely supply, would be like a series circuit component damage caused by paralysis of the entire circuit, as will cause the entire machine production line shutdown, but if there is no rapid response emergency measures or not, there may even result in the automatic assembly line assembly line shut down, we can see a significant impact on the production of the tool and its management.

You get what you pay for. Good machine configuration, good quality accessories, the price is certainly high; Tool is the same material on the high price is certainly a good tool.

Tips:Select the tools to be divided into two phases. 

The first stage is the period of operation of the machine learning exercise at this stage of our proficiency, experience is still in the beginning stage, this time do not use the relatively high price of the tool to practice experiments, we may erroneous operation will be a tool ruin

The second stage is mastering stage, because this time whether it is operating skills, operational proficiency, experience in all aspects with a certain strength, we can use some good tools, whether affirmative or value of processing efficiency and processing quality of praise.

Tool selection should be selected depending on the material, density is relatively uniform can select normal quality tools can be, the more complex material density must choose relatively sharp edge.

Laser engraving technology

                                         Laser engraving technology

With the rapid development of electronic technology, laser engraving technology range more widely, increasingly demanding high precision carving.

The most fundamental element of effecting laser engraving: Engraving speed, laser power, engraving precision and materials. On the specific materials to achieve a certain effect engraving, requires absorb some energy laser, this energy should be seen as a material to absorb the laser energy = laser power / engraving speed. 

Briefly that if improve the material absorbs laser energy, it should improve the laser power or reduce engraving speed, As for choose which method depends on the material and the final engraving effect. 
In general, users will avoid the high and low speed, because it would reduce production efficiency. In fact, not only the speed affect the efficiency , but also the carving precision have a very big impact.

Laser engraving process is the use of numerical control technology, laser-processing medium. Processing materials melting and vaporization of instant physical degeneration in the laser irradiation, to achieve the purpose of processing.

Laser processing characteristics:
 No contact with the material surface, without mechanical movement affected ,surface will not be deformed, generally without fixed,  not affected by the material flexibility and elasticity, convenient for soft materials. High precision, high speed, wide range of applications

Laser system into laser cutting, laser engraving, laser marking..
Laser engraving is widely used in advertising processing, gift processing, packaging engraving, leather cutting, fabric proofing, seal carving, product marking, rubber carving and many other industries.

Common laser engraving material:
1, Non-metallic materials processing (co2 laser): plexiglass, wood, leather, fabric, plastic, printing rubber , color plates, glass, synthetic crystal, horn, cardboard, MDF, marble, jade and so on;
2,Metal processing (YAG laser) common metallic materials. 

Laser engraving principle
Laser engraving and cutting, the process is very simple, as the use of computers and printers to print on paper.
 You can use in the Win98 / Win2000 / WinXP environment ,use a variety of graphics processing software, such as CorelDraw and other design, scanned graphics, vector graphics and a variety of CAD files can easily "print" to the engraving machine. The only difference is, print the toner applied to the paper, Laser engraving is the laser hitting the materials.

Lattice engraving

Lattice engraving resembles high-resolution dot matrix printing. Laser head from side to side, each carving out a series of points of a line, then the laser head moves up and down while carving out a number of lines, and finally constitute a full-page image or text. Graphics, text and vector graphics can be used to scan a lattice engraving.

Vector Cutting

With different lattice carving ,vector graphic cut in the outer contour line. We usually use this mode on wood, acrylic, paper and other materials for penetrating cutting,Also can operate in a variety of marking material surface. 

Laser Engraving speed:
Engraving speed refers to the speed of the laser head movement, usually represented by IPS (inches / sec) High speed means high productivity. 

Speed is also used to control the cutting depth, for a specific laser intensity, the slower the speed, the depth of cutting or carving the greater.
 You can use the machine panel to adjust the speed , also can use the computer printer driver to adjust. In the range of 1% to 100%, the adjustment is 1%

Spot size
Laser beam spot size can be adjust byehe lens of different focal lengths . Small spot lens for high-resolution engraving.  big spot lens for a lower resolution carving, but for vector cutting, it is the best option. Standard configuration of the new device is 2.0-inch lens. Its spot size in the middle, for a variety of occasions.

Advantage of the laser processing
Wide range: a co2 laser machine can working with almost any non-metallic materials. And low prices!
 Safe and reliable: use of non-contact processing, the material does not cause mechanical compression or mechanical stress. No "marks" and does not harm the surface of the materials; do not deform the material;
 Meticulous precision: machining precision can reach 0.02mm;
Environmental conservation: Beam and the spot diameter is small,generally less than 0.5mm; cutting to save material, safety and health;
Consistent results: Ensure that the same batch of processed exactly the same effect.
High-speed fast: can immediately speed engraving and cutting according to pattern that computer output.
Low cost: not limited by the number of processing, and cheaper for small batch processing services.                                                             ----Amor CNC Laser.com

How to laser engraving &laser etched glass

                                     How to laser engraving &laser etched glass

The laser can be engraved on the glass surface, but the engraving depth is not deep and can not be cut.Laser engraving on the glass surface with frosting or crushing effect.

Most users want to get frosting instead of crushing effect, this depends on the texture of the glass, and whether the hardness are the same.

Glass engraving is difficult to control, in accordance with the

Following steps can make a relatively smooth surface matte effect:

1.Smear a little detergent on the engraving area, use a newspapers or napkins slightly larger than the area;

2.The paper completely soaked wet with water, and squeeze the excess water ,put the wet paper on the engraving area, do not wrinkled.

3.Put the glass on the engraving machine, engraving when the paper wet state, and then take out the glass, remove residual paper, then clean the glass surface.

4.If necessary, gently polishing the glass surface with 3M's Scotch Brite.

Normally, the laser power settings should be smaller, precision setting at 300dpi, engraving speed to be faster, you can try using large-size lens for carving. 

Note: When laser engraving on leaded crystal should redouble careful, leaded crystal and

ordinary crystals have different coefficients of expansion, in the carving which may cause crystal cracks or broken. 

Settings small power to avoid this problem, but still should always guard against rupture in case.

Clean, you can use a damp cloth to clean after engraving surface.

　　

Coloring, can be used acrylic paint coloring.
