There are still a lot of furniture market in the home improvement industry. There is also a big market for the demand for crystal characters and pvc. After years of technological development, woodworking engraving machines can also process crystal characters and pvc. Now, if you want to use crystal engraving machine to process crystal characters and pvc, what are the requirements when setting parameters, what kind of precautions should be made in the process of processing? Next, follow the CNC network Xiaobian to understand the woodworking engraving machine processing crystal word pvc skills Woodworking engraving machine processing crystal word method related content!
1 typesetting (the graphics are arranged according to the principle of saving materials) to generate the tool path.
On the 2nd page, the point is “cut” for calculation. According to the quality of the data itself.
3 woodworking engraving machine to modify the direction of the machine processing (to help smooth the edge of the graphics. Generally do not need to reverse) according to the choice of material selection counterclockwise, clockwise (PVC clockwise, acrylic counterclockwise) 4 notes hollowing out Inner contour, 1 2D cutting inner contour, outer contour, original line output. The crystal word uses the outer contour, and the inverted line is output with the original line. The three-dimensional picking angle is not checked when cutting. If you do mosaic, the mosaic path is hooked, the interval is generally 0.2 and then subtract the engraving depth set by the computer. 2 When machining, the Z-axis origin is first to the outer surface of the bottom plate. 3PVC Fron plate processing as much as possible to mirror the original file. Acrylic cutting below 10mm: spindle speed (18000-20000: engraving speed (400-800 moving speed (1500-2200 speed depends mainly on the spacing between processing graphics) 10mm or more acrylic cutting spindle speed (18000-24000: Engraving speed (250-600 moving speed (1500-2200 speed depends mainly on the spacing between processing graphics 310mm below PVC cutting: spindle speed (18000-24000: engraving speed (1000-1500 moving speed (1500-2200 speed depends mainly on Between the processing graphics) 410mm or more PVC cutting: spindle speed (18000-24000: engraving speed (800-1500 moving speed (1500-2200 speed depends mainly on the spacing between the processing graphics) spindle speed takes the upper limit, Note: 1 The thicker the engraving material, the lower the engraving speed.
Commonly used tools: 12mm (cut 10MM and below thickness) 17mm (cut 15MM) 22mm (cut 20MM) Because the melting point of PVC material is lower, generally there will be partial melting phenomenon at the edge of the material surface, which needs to be modified with a utility knife. It affects the aesthetic effect of the word, and the surface of the table is smooth and flat. Therefore, we recommend: when cutting the PVC word, first mirror the processing object and then calculate the tool path, so that the word face is facing down, that is, the word edge is smooth and neat.
To keep the size of the word when cutting, you need to select the outer contour cutting; and when calculating the two-color board and the PVC cutting path, you should select the “clockwise” calculation path.
The above woodworking engraving machine parameters are for reference only. The above parameters are related to operating experience, machine performance, tools, and materials. It is recommended that the operator practice according to the above parameter data to form self-data, that is, actual operation data.
