generate tool path meaning in Chinese

生成刀位轨迹

The methodology adopted by most existing cam / cnc systems , which uses huge amount of linear segments to approach the original shape and make linear interposition increases the cost of memory size and communication work of the cnc system tremendously . a new approach based on cubic polynomial and b spline interposition to rebuild the cam generated tool path under real time condition is presented in the paper . applications on cnc machine tools showed that the presented approach improves the machining accuracy and increases the cutting speed significantly
目前大多数cam / cnc系统采用大量小直线段逼近原始曲线和直线插补的做法，只能获得零阶连续的走刀轨迹，逼近精度低，不能保证高速加工运动的平稳性，因而加工精度、光洁度和加工速度都难以提高；由小直线段构成的nc代码数据量庞大，也增加了数控系统在内存容量和数据传输方面的成本。
