The same is true for precision parts processing. So what is the possibility and convenience of precision parts processing? The speed of development of the precision parts processing industry is also getting faster and faster. Moreover, in all aspects, the role of precision parts processing is slowly increasing. Reflected, in all aspects, it is better to process precision parts in the equipment. After the improvement, the workmanship has also increased a lot.
Mainly, the size data on the part processing drawing should meet the programming guidelines
The conditions of the geometric elements constituting the contour of the part should be sufficient
(1) The dimensioning method on the part drawing should conform to the characteristics of CNC machining. On the precision part processing drawing, the dimensions should be quoted on the same basis or the coordinate dimensions should be directly given.
1. This marking method is not only convenient for programming, but also for mutual harmony between dimensions, and it brings great convenience in adhering to the divergence of design benchmarks, process benchmarks, testing benchmarks and programming origin settings.
2. As part designers usually think more about the application characteristics of assembly in the dimensioning, they have to adopt a partially scattered marking method, which will bring a lot of inconvenience to the process layout and CNC machining.
3. Since the precision parts processing accuracy and repeated positioning accuracy are very high, the application characteristics will not be damaged due to large accumulation errors, so the local dispersion marking method can be changed to the same reference size or the coordinate size can be directly given. The notation method.
(2) Calculate the base point or node coordinates during manual programming. In automatic programming, precision parts processing must stop defining all geometric elements that constitute the contour of the part. Therefore, when analyzing the part drawing, it is necessary to analyze whether the given conditions of the geometric elements are sufficient.
