查询词典 machining

When the system starts displaying machining animation, it does not need to calculate small triangular facets normal to the workpiece surface. It only needs to find out what part of the cutter cuts the workpiece surface and to read the normal from the file.

当显示加工动画时不必再计算毛坯表面小平面的法向量，仅仅需要计算是刀具的哪部分切削了该小平面，然后从文件中读出对应的法向量。
