In the process, the tool chucking length of the shorter, the better the rigidity of the tool. However, chucking length is too short, the motor might collide with the workpiece interference. Interference Detection analysis can chucking length and the length of the blade surface models based on different tools, tool path, size of the motor, so as to provide a theoretical basis for the correct knife.

SurfMill interference checking tool features:

· Calculation tool based on the current path and machining scrap the minimum blade length;

* Depending on the tool length and shape of the workpiece and tool path detecting whether the chuck interference;

· Whether the interference based on the lower end of the geometric characteristics of the motor to detect motor;

· Automatically prompt the shortest length of the knife according to interference conditions;
