介绍了一种铜冶金炉快速热修机器人在拆除耐火砖作业时的运动轨迹，对运动轨迹过程中的进给点及其相应的各轴进给量进行了分析，并提出了一种实现其运动轨迹的方法。

Planer is to adopt a working table to compose linear motion moving back and forth with workpiece but then , the cutter assumes but blank feed the motion moving assigning a form transversely.

而龙门刨床则是采用工作台带着工件作往复直线运动，而刀具作间歇的横向进给运动的运动分配形式。

It identifies "worse condition points" along the path according to the curve information, machine tools capability and machining requirement. Integrated with adaptive interpolation, segmented high speed machining is adopted. Different constant speed segments and speed transition segments are obtained according to the feed motion constraint model, and the corresponding feed information are stored in a penta-element lookup chain table. By referring to the lookup table, the interpolator can automatically determine the feed motion.
