What do you need to know about CNC machining? CNC machining will use the coordinate system and know the relationship between machining coordinates and design coordinates. Be familiar with two-dimensional cutting path, contour, parallel machining and three-dimensional equidistant machining, be able to divide shallow and steep surfaces, understand the relationship between tolerance and allowance, understand the calculation of the boundary of the machining surface, understand the calculation of the dividing line of shallow and steep surfaces, and understand the control method of surface roughness.

Be familiar with the post-processing methods of three control systems, familiar with ISO codes and manual programming. Understand the mold structure, and be able to disassemble copper. Familiar with cutting parameters of common tools. Familiar with the effect of hardness of cutting materials on parameters. I can barely write a complete knife path. I can't control the second opening. I don't have a deep understanding of the light knife. The next program can only be written after the cutting result is checked by one program. The product or mold size produced by the Gong is not correct, and there are knife marks between the two knives. I can't rest well at night. Understand that software is only a tool to express ideas, and be willing to learn more about metal cutting technology, tools, materials, products and molds.

In addition, the CNC processing software is skilled, the shortcut keys are skilled, the operation is smooth, the mold assembly is understood, the remaining amount of the processing surface is how to cooperate with the mold assembly, the product problems caused by the remaining amount of the processing surface and the product assembly problems in the future are known, and the conservative processing is known to prevent the mold assembly and product structure and assembly problems in the future. Be familiar with data security. Know how to process the positioning of products that need to be processed on six sides. For copper steel bars that are easily deformed, steel materials know how to cut. Learn how to map the residual materials for the half opened rough dies with the milling machine to save time or prevent tool collision.

Be able to face the problems of product design and actively change the product design to meet the rationality of mold structure and processing. Can accurately calculate the processing time, and can quote for CNC processing of products. Accurate calculation of design cost and processing cost. Good at communicating with customers. Capable of wire cutting drawings. Drawing of copper male positioning. Can disassemble the copper Gong that is not complicated.
