In precision part machining, the path of tool position relative to part motion is called machining path. The processing routes are as follows.
Hole processing route: The hole processing route refers to the distance between the tool tip position and the upper surface of the hole when the tool changes from fast forward to tool forward during hole processing. The processing route of the hole system with high mutual position accuracy. For the processing of the hole system with high position accuracy requirements, special attention should be paid to the arrangement of the hole processing sequence to avoid bringing the directional clearance of the coordinate axis into the hole system and affecting the position accuracy.
Cleaning and processing route of the contour: When the side edge of the end mill is used to clean the contour parts, in order to reduce the tool receiving trace and ensure the surface quality of the parts, the cutting in and cutting out points of the milling cutter shall cut into the part surface along the tangential direction of the extension line of the contour curve of the parts, instead of directly cutting into the parts along the normal direction of the contour curve of the parts, so as to avoid tool marks on the processing surface and ensure the smooth contour of the parts.

Machining route of groove workpieces: There are three methods for machining grooves, namely, line cutting, circular cutting and first cutting and last circular cutting.
The above three are the three workpiece processing routes used in precision parts processing.
