在电火花线切割加工中,常出现预定切割轨迹与加工后图形不一致的情况。它影响和限制了线切割加工技术的广泛应用,特别是在精密微细加工中的有效使用。在线切割控制系统和机床机械传动系统正常情况下,加工的工件经常因材料变形而导致切割轨迹与加工后图形不一致。有时,在切割过程中,材料会在切缝处猛然炸开,甚至可能会崩出几米之远。本文讨论变形产生及防止措施。
In the WEDM machining, often appear scheduled cutting trajectory and processing graphics do not match the situation. It affects and limits the widespread use of wire cutting technology, especially in the precision microfabrication of the effective use. On-line cutting control system and machine tool mechanical transmission system Under normal circumstances, the processing of the workpiece is often due to deformation of the material resulting in cutting trajectory and processing of the graphics are inconsistent. Sometimes, during the cutting process, the material explodes suddenly at the kerf and may even collapse a few meters. This article discusses the deformation and prevention measures.
