The roughing strategy depends on the type of blank and the condition of the mold surface. If the blank is a forging or steel, it is best to use the area removal model first for rough machining, and remove most of the remainder of the blank to obtain a uniform blank allowance, which is convenient for subsequent processing.
The main purpose of semi-finishing is to ensure uniform margins during finishing. The most common method is to first calculate the boundary contour of the residual material (refer to the 3D contour of the tool's unprocessed area), and then use a smaller tool to process these 3D contour areas. Without having to rework the entire model.
3． Local finishing
Local finishing generally refers to clear angle machining. Clearing angle processing should use multiple processing or a series of tools from large to small processing methods.
In finishing, unless the mold profile height changes greatly, it is better to choose parallel finishing.
