What are the criteria for giving the scale data on the stainless steel parts processing drawing to fit the programming convenience?
1. The scale marking method on the stainless steel parts drawing should adapt to the processing characteristicshttps://titanium-machining.com/
On the stainless steel parts processing drawings, the same reference scale should be cited or the coordinate scale should be given directly.

This marking method not only facilitates programming, but also facilitates mutual coordination between standards, and brings great convenience in maintaining the consistency of planning benchmarks, process benchmarks, inspection benchmarks and programming origin settings. As part planners generally consider assembly and other use characteristics in scale labeling, they have to choose partial labeling methods, which will bring a lot of inconvenience to process organization and stainless steel parts processing. https://beryllium-copper.com/Because stainless steel parts have high machining accuracy and repeat positioning accuracy, they will not damage the use characteristics due to large accumulated errors. Therefore, part of the scattered labeling method can be changed to the same reference citation scale or directly given the coordinate scale label. law.
2. The conditions of the several elements that constitute the generalization of the parts should be sufficient
The base point or node coordinates should be calculated during manual programming. In automatic programming, it is necessary to define all the several elements that make up the part. Therefore, when analyzing the part drawing, it is necessary to analyze whether the given conditions of the few elements are sufficient. For example, the arc and the straight line, the arc and the arc are tangent on the drawing, but according to the scale given on the drawing, when the tangency condition is calculated, it becomes the state of intersection or separation. Due to the inadequate conditions of the constituent elements, it is impossible to start programming. When encountering this kind of situation, you should discuss with the part planner to solve it.

Stainless steel parts processing
What are the characteristics of CNC machining that the structure and craftsmanship of stainless steel parts processing parts should fit in?
1) It is recommended to use the same geometry type and size for the cavity and shape of the parts. This can reduce the tool standard and the number of tool changes, facilitate programming and improve production efficiency.
2) The size of the fillet of the inner groove determines the size of the tool diameter, so the radius of the fillet of the inner groove should not be too small. The manufacturability of parts is related to the roughness to be processed and the size of the transition arc radius.
3) When milling the bottom surface of the part, the fillet radius r of the groove bottom should not be too large.
4) Consistent reference positioning should be used. If stainless steel parts are processed without consistent reference positioning, the reinstallation of the workpiece will cause the general orientation and scale of the two faces after processing to be inconsistent.https://china-turning.com/ Therefore, to prevent the occurrence of the above-mentioned problems and ensure the accuracy of the relative orientation after two clamping processes, a consistent reference positioning should be selected.
It is recommended to have suitable holes as positioning reference holes in the processing of stainless steel parts. If not, set process holes as positioning reference holes (such as adding process lugs on the blank or setting process holes on the margin to be milled in the subsequent process). If the process hole cannot be made, at least the finished appearance should be used as a consistent benchmark to reduce the errors caused by the two clamping. In addition, it should also analyze whether the required machining accuracy and dimensional tolerances of the parts can be ensured, whether there are redundant dimensions that cause contradictions, or closed dimensions that affect the process organization.
