1. Rough machining

Rough machining strategy needs to be determined according to the type of blank and mold surface. If the blank is forgings or steel, then rough processing had better choose the area clearance model processing, the bulk of the blank to remove, get uniform blank margin, for the convenience of the subsequent processing.

2. semi-finishing

The main purpose of semi-finishing is to ensure uniform allowance during finishing. The most common method is to first calculate the boundary contour of the residual material (refer to the 3d contour of the unmachined area of the tool), and then select a smaller tool to process these 3d contour areas, without reprocessing the entire model.

3. Local finishing

Local finishing generally refers to corner cleaning. Angle cleaning machining should adopt multiple machining or series of cutting tools from large to small machining method.

4. finishing

In finishing, it is better to choose parallel finishing unless the mold surface height changes greatly.
