Type of mold processing

1. Rough machining
The rough machining strategy needs to be determined according to the type of blank and the condition of mold surface. If the blank is a forging or steel part, it is better to select the area clearing model for rough machining first, and remove most of the blank allowance to obtain a uniform blank allowance, which provides convenience for subsequent processing.
2. Semi-finishing
The main purpose of semi-finish machining is to ensure uniform allowance during finish machining. 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 re-machine the entire model.
3. Local finishing
Local finishing generally refers to corner cleaning. The angle cleaning process shall adopt multiple processing or a series of tools from large to small.
4. Finishing
In finish machining, unless the height of mold surface changes greatly, it is better to select parallel finish machining.
