等误差直线逼近非圆曲线的节点计算及刀具轨迹模拟

Calculation of Nodes and Simulation of Tool Path by Equal-error Method to Approach Non-circular Curve with beeline

介绍了数控编程时采用等误差直线逼近法模拟非圆曲线刀具轨迹的节点计算方法 。

The calculation method of nodes is introduced to simulate the tool path with non circular curve by using the equal error beeline approaching method in NC programming. The corresponding calculation program is developed by using VBA which is embedded in AutoCAD.
