AutoCAD曲线的坐标变换和最值求取

The Coordinates Transformation and the Extreme Value Approaches of the Curves in AutoCAD

给出了AutoCAD环境下的木工成型铣刀CAD系统中 ,用户输入的工件截形曲线通过坐标变换生成木工成型铣刀前刀面截形曲线的方法 。

This paper provided a coordinate transformation method of transforming the wooden work curves into the curves of front edge of formed milling cutter,and further discussed how to get the extreme point of curve under the AutoCAD environment.
