The emergence of some processing methods has greatly improved our industry and all aspects of the role. The performance in all aspects is also very good. The precision parts processing is also the same. So what is the possibility and convenience of precision parts processing? The following is explained in detail by the editor of CNC precision parts processing.
Mainly the size data on the part processing drawing should fit 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 given directly.
1. This marking method is not only convenient for programming, but also for the harmony between dimensions, and it brings great convenience in adhering to the divergence of design benchmarks, process benchmarks, inspection benchmarks and programming origin settings.
2. Because part designers usually think more about the application characteristics of assembly in dimensioning, they have to adopt a partially scattered marking method, which will bring a lot of inconvenience to process layout and CNC machining.
3. Since precision parts have high machining accuracy and repeat positioning accuracy, they will not damage the operating characteristics due to large accumulation errors. Therefore, the local dispersion labeling method can be changed to the same reference size or directly The labeling method of the coordinate size.
(2) Calculate the base point or node coordinates during manual programming. During 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.
The above is the knowledge introduced by the editor of CNC precision parts processing. If there is anything you don’t understand, you can follow the latest developments on our website and consult the website address: http://www.dghongye.com/
