正确选择刀具可以大大减少数控加工时间。大多数研究人员根据刀具路径生成来选择刀具，这非常耗时，并且只能选择非常有限的刀具数量。介绍了一种基于有效干涉检测算法的复杂模具加工的新刀具选择方法。通过这种方法，首先确定候选刀具的可行区域，而无需生成刀具路径。然后根据可行区域的面积和刀具进给速率来估计不同刀具组合的加工时间。选择能够以最短时间加工工件的刀具组作为最佳候选刀具。由于在选择刀具之前不需要生成刀具路径，因此可以有效地选择刀具，并且数控加工中可以使用的刀具数量可以相当大。该系统已经过多个工业零件的测试，可以有效且高效地选择最佳刀具。
Proper cutter selection can reduce NC machining time greatly. Most researchers select cutters based on tool path generation, which is very time consuming, and only a very limited number of cutters can be selected. A new cutter selection methodology for complex mould machining based on an efficient interference detection algorithm is introduced. With this approach, the feasible regions for the candidate cutters are first identified without tool path generation. The machining times for different cutter combinations are then estimated based on the areas of the feasible regions and the cutter feed rates. The set of cutters that can machine the workpiece with minimum time is selected as the optimal candidate cutters. Since no tool path needs to be generated before cutter selection, the cutters can be selected efficiently, and the number of the cutters that can be used in NC machining can be quite large. The system has been tested with several industrial parts and it can select optimal cutters effectively and efficiently.
