摘　　要：以椭圆形零件的数控加工为例,阐述了逼近法在非圆曲线形零件数控加工中的应用。由于一般数控机床的编程代码只具有直线插补和圆弧插补功能,因此对于非圆曲线的数控加工大多采用小段直线或小段圆弧去逼近轮廓曲线,完成数控编程。Takes CNC Machining of ellipsoid parts for an example, this paper has explained the CNC Machining Technology of the non-circular curve parts with approaching way. As the general programming of numerical control machine code only has a straight line interpolation and circular interpolation function, so the CNC machining of non-circular curve used mostly short line or short arc to close the outline curve and complete CNC programming.

关 键 词：数控加工 非圆曲线 逼近法
