Precautions for front mold processing
1. The order of the tool paths: is the rough surface grooving tool path rough? Is the knife path thicker with the height profile of the knife? Large knife (ball knife) parallel milling cutter path light knife? Small knife parallel milling cutter path light cutter. When the front mold is manufactured, there is a matching copper male, which is mainly based on rough tool paths, supplemented by local curved light tools.
2. With the parting surface and the pillow surface, it is necessary to add time together, the parting surface pillow surface is processed in place, and no margin is left, and V-core is added: UG5209 collar free CNC course cavity part to leave a margin of 0.2--0.5 , for sparks. If there is only a young male, leave a margin of 0.3. For rough and young males, a margin of 0.5 can be left. A margin of 0.1 can be reserved for the touch-through position and the wipe-through position of the front mold, which is used for the front and rear molds to match the molds.
3. Use a large-diameter round nose knife (knife handle) when opening rough, the knife diameter is too small, and it is easy to break the knife and bounce the knife. It is also used as much as possible when the knife is in the middle.
4. The tool path range in surface machining Q is calculated based on the movement path of the tool center axis, that is, the actual dynamic processing area is more limited than the selected tool path range.
One side of the fixed frame is larger by one tool radius value, and the parameters of the tool path range limit frame should be set reasonably. Avoid processing beyond the actual processing needs.
5. The material of the front mold is hard, and it should be checked carefully before processing to reduce errors and cannot be easily welded!.
