русский1. roughing
The rough machining strategy needs to be determined according to the type of blank and the condition of the mold surface. If the blank is forging or steel, then it is best to choose the area clearing model for rough machining, and the Most of the margin of the blank is removed to obtain a uniform blank margin, which provides convenience for subsequent processing.
2. semi-finishing
The main purpose of semi-finishing is to ensure a uniform allowance during finishing. The most common method is to calculate the boundary contour of the remaining material first (refer to the three-dimensional contour of the unprocessed area of the tool), and then use smaller tools to machine these 3D contoured areas without having to remachine the entire model.
3. Partial finishing
Local finishing generally refers to corner cleaning. The corner cleaning process should adopt multiple processing or a series of cutting tools from large to small.
4. finishing
In finishing, unless the height of the mold surface varies greatly, it is best to choose parallel finishing.
