数控铣削进给路线的确定

Determination of feeding path in NC milling

在补充完善现有数控铣削进给路线的确定原则基础上,结合实例阐述了如何合理确定进给路线,即沿零件轮廓线的延长线或切线切入切出,在保证质量的前提下使进给路线最短.实践证明,如此确定的铣削进给路线不仅路线最优,并且可使加工时间减少近50%,从而大大提高生产效率.

Based on suppling and completing the determination principle of feeding paths in NC milling, combining with should be noted a example, feeding paths for common shape in NC milling machining was determined. It that cut in or out along the part contour lines or tangent, and in the premise of quality, can get the shortest route. Practice showed that reasonable feeding paths in milling not only makes the paths optimal, but also makes the processing time reduced by almost half, which greatly improves the production efficiency.
