数控渐进成形与数控铣削既有共同之处也有不同之处。针对目前在数控渐进成形研究中都采用数控铣削模式的加工轨迹,并且对于残余高度的计算也都采用依据铣削加工模式计算方法的问题,通过对比分析数控渐进成形件与数控铣削件的表面残余高度,研究了数控铣削加工模式中残余高度计算方法在数控渐进成形中的可应用性,以及等残余高度轨迹在数控渐进成形中的实用性。研究结果表明,数控铣削加工中残余高度的计算方法和等残余高度轨迹在数控渐进成形中具有可应用性。 CNC progressive forming and CNC milling have both common and different. Aiming at the current situation of numerical control milling mode in the research of numerical control progressive forming, the calculation of residual height is also based on the calculation method of milling mode. Through comparative analysis of the surface residual height of NC progressive forming part and NC milling part, , The applicability of the method of calculating the residual height in NC milling mode in progressive forming of numerical control is studied, and the practicability of the residual height trajectory in numerical progressive forming is studied. The results show that the calculation method of residual height and the residual height trajectory in CNC milling have applicability in numerical control progressive forming.
