An identification algorithm for tool interference in NC machining is presented based on the fuzzy inference techniques and pattern recognition theory.

基于模糊推理的自由曲面描述方法和模式识别理论，提出一种适用于不同刀具类型并可同时考虑刀具底面干涉和侧面干涉的刀具干涉判别算法。

The overcutting on tool end is checked via comparing the tool radius with the circumradius or the radius of inscribed circle, and the touch interference of tool body based on the symbol of the vector distance from the triangle vertex to the tangent plane of tool body column.

在曲面加工的无干涉路径规划中，通过恰当选择刀具初始位置避免了接触点处的曲率干涉；通过比较刀具半径与曲面上三角片外接园半径的大小即可判断刀具底面干涉；而根据三角片顶点与刀杆切平面的有向距离的正负来判断刀杆碰撞干涉。

Third, in processing, the arc length of cutter on the pitch curve was equal to be the length of cutter rotating around its axis in order to guarantee the generating between the pinion cutter and the blank.

第三，在加工过程中，为保证刀具和齿坯之间的范成关系，刀具在齿坯节曲线上滚过的弧长等于刀具绕其自身回转中心转过的弧长。

Problems that result from high-speed movement of the equipment in measurement unit, including image mistiness, repetition and skip, are deeply analyzed. And the processing time is tested.
