Figure 1 CNC lathe turning end face machining route

The machining route of the CNC lathe turning outer circle is shown as ABCDEF, where A is the tool change point, B is the cutting point, CDE is the tool cutting path, E is the cutting point, and F is the retracting point.

2 CNC milling machine processing route

When the side cutter of the end mill mills the outer contour of the plane part, it avoids the normal cutting and cutting along the outer contour of the part. As shown in Figure 3, it should be cut or cut along the tangential extension of the outer contour curve. The cutting edge cuts produced when cutting in or cutting out ensure a smooth transition of the part surface. When milling the inner contour surface, the tool also enters and retracts along the tangential direction of the contour line. As shown in Fig. 4, ABC is the tangential cutting path of the tool, CDC is the closed contour of the tool cutting workpiece, CEA Cut the contour path for the tool tangentially.

3-hole machining positioning route

Reasonable arrangement of the hole machining positioning route can improve the positional accuracy of the hole. As shown in Fig. 5, the four holes A, B, C, and D are processed in the XY plane, and the alignment direction of each hole must be paid attention to when arranging the hole processing route. That is, the unidirectional approach positioning method is adopted, after the C hole processing is completed, the distance is moved to the left for a certain distance, and then the processing is returned to the D hole. This positioning method avoids the positioning error caused by the backlash of the transmission system, and improves the D hole and other Positional accuracy between holes.
