Mold processing type
1. The rough machining
The rough machining strategy needs to be based on the type of the blank and the mold surface.If blank for forgings or steel pieces, so it's best to choose rough machining area clearance model processing, the blank to get rid of most of the surplus, the blank allowance is evenly, provide convenience for after order processing.
2. Semi-finishing
Semi-finishing of main purpose is to ensure uniform when finish machining allowance, the most commonly used method is to calculate the residual material boundary contour (reference tool three-dimensional contours of unprocessed area), and then choose a smaller tool for processing the three-dimensional contour area, without processing the entire model.
3. Local finishing.
Local precision processing is generally referred to as clearing Angle processing.It should be used for machining or series cutting tool from large to small.
4. The finishing
In the finishing process, unless the mold surface height change is relatively large, it is better to choose parallel processing.
