The path of the tool is the trajectory and direction of the tool relative to the workpiece during the index control process.A reasonable choice of the machining route is very important because it is closely related to the machining accuracy and surface quality of the part.The following points are mainly considered in determining the route:
Miscellaneous CNC machining
1.Ensure the machining accuracy requirements of the parts.
2,convenient numerical calculation,reducing the amount of programming work.
3,seek the shortest processing route,reduce the empty knife time to improve processing efficiency.
4.Try to reduce the number of blocks.
5.To ensure the roughness of the contour surface of the workpiece after processing,the final contour should be arranged for the last pass to be continuously processed.
6,the tool's advance and retreat knife(cut in and cut out)route should also be carefully considered,in order to minimize the knife at the contour(the sudden change of cutting force caused by elastic deformation)leaving the tool marks,but also to avoid vertical under the contour surface Scratch the workpiece with a knife.
The above is the introduction of the selection of the CNC machining path,the selection of the CNC machining route is very important,because he directly determines the accuracy and surface quality of the workpiece.Only the choice is made to ensure the quality of the machined parts.
