【Abstract】 A PC-based CNC system for gear shaping its functional structure and hardware construction are introduced. The basic NC programming steps for self-defined sector and gear shaping are investigated. Calculating feed rate according to the shaping error. a difficult problem in NC programming, is solved by a two step method (fitting and iterating). For the purpose of obtaining a high shaping accuracy, a new realtime interpolation algorithm is presented for selfdefined locus interpolation. A high efficient and reliable shaping process is planned under the consideration of the shaping feature. At the end of the paper, an example is given with shaping accuracy.更多还原
