4.2.5 Tool Interference Check
“Interference” is defined that the tool cuts workpiece excessively and it can find out excessive
cutting in advance, the interference check is executed even if the excessive cutting is not created, but
the system cannot find out all tool interferences.
(1) Fundamental conditions
1) The tool path direction is different that of program path (angle is 90°~270° ).
2) There is a big difference (
α
＞
180°
) for two angles between starting point and end point of tool
nose center path, and between starting point and end point of program path.
Example: linear machining
