How to choose the machining path

 
The machining tool path refers to the movement trajectory and direction of the tool relative to the workpiece during the machining process. The selection of machining tool paths is very important, which is inseparable from the machining accuracy of the workpiece and the machining quality of the workpiece. The conventional technical requirements for machining of various workpieces also have a very important impact on the selection of machining tool paths. Therefore, mechanical How to choose the machining path?
1. Ensure the machining accuracy of the parts.
2. It is convenient for numerical calculation and reduces the workload of programming.
3. Seek the shortest processing route and reduce the idle time to improve processing efficiency.
4. Minimize the number of program segments.
5. To ensure the roughness of the workpiece surface after machining, the final contour should be processed continuously in the last pass.
6. The advance and retraction route of the tool should be carefully considered to minimize the stop of the tool at the contour (elastic deformation caused by the sudden change of cutting force) and leave tool marks, and also avoid cutting the tool vertically on the contour surface and scratch the workpiece.
The selection of machining toolpaths is very important, which directly affects the accuracy, quality and processing efficiency of machining workpieces. Therefore, choosing the appropriate machining toolpaths can save a lot of unnecessary cost waste.
