Copper processing method and precautions

2023-07-20

Before writing the passes, after drawing the stereoscopic drawing, the center of the graph should be moved to the coordinate origin, and the highest point should be moved to Z=0 before it can be processed, and the copper spark position can be processed with negative reserves. Before processing, it is also necessary to check whether the clamping direction of the workpiece is the same as the graphic direction in the computer, whether the position in the mold is correct, whether the clamping tool hinders the processing, and whether the direction of the front and rear molds matches. Also check whether the tools you use are complete, the benchmarks in the calibration score, etc.

Matters to pay attention to when processing copper gong: the determination of the spark position, the reserved amount of a young male (that is, the fine gong) is 0.05~0.15, the rough male 0.2~0.5, and the specific size of the spark position can be determined by the mold master. There is no dead corner that the copper public cannot be processed, and whether it is necessary to disassemble one more scattered male.

The tool paths of the processing copper workers are generally arranged according to the row: large knife (flat knife) open thick - small knife (flat knife) corner clearing; Lightsabers use ball cutters to light curved surfaces. Open rough general teachers use flat knives without ball knives, after the big knife with a small knife to open thick, and then the shape light to count, then use a large ball knife light surface, and then use a small ball knife light surface do not try to save trouble, for some small angles and use a small knife to process the large knife can not pass the dead corner can carefully limit the scope of the knife, so as not to broadcast too many empty knives. Copper male, especially young male, is relatively high precision requirements, tolerance is generally selected 0.005~0.02, step distance 0.05~0.3. When the copper is open rough, the passing position of the ball tool position should be left, that is, the copper male shape should be opened by one knife radius. The copper gong should also be processed into the median, calibrated the gauge reference, and the copper gong should be corrected when the spark is discharged, and the copper male processed by the general calibration of three sides (up, down, left, right) must have three datums. Copper is a relatively easy to process materials, tool speed, speed can be faster, rough, leaving a processing margin of 0.2 ~ 0.5, depending on the size of the workpiece, the processing allowance is large, the tool can be fast when the rough is opened, improve efficiency.

Note: In parentheses are the parameters when the high-speed steel knife is rough to the steel, and the above pass speed refers to the light shape F=300~500 when the rough is opened, and the steel blade F is 50~200.
