The rough machining strategy needs to be determined according to the type of blank and the mold surface. If the blank is a forging or a steel part, it is best to select the area removal model for rough machining, remove most of the blank margin, and obtain a uniform blank margin, which provides convenience for subsequent processing.
The main purpose of semi-finishing machining is to ensure uniform margin during finishing. The most common method is to first calculate the boundary contour of the residual material (refer to the three-dimensional contour of the unprocessed area of the tool), and then select a smaller tool to process these three-dimensional contour areas , Without having to rework the entire model.
3. Local Finishing
Local finishing generally refers to clear corner processing. Clear corner processing should use multiple processing or a series of cutting tools from large to small processing method.
In finishing, it is best to choose parallel finishing unless the height of the mould surface changes greatly.
