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, at the moment, No.257 alarm occurs
(the angle is 90°~270°). The alarm does not occur when No.5008 Bit1 (CNC) is set to 1.
2) In machining arc, there is great difference the two angles( α
＞
180°), the one is between the
starting point and the end point of the tool center path, and the other is between the starting
point and the end point of the programmed path, or the system cuts the inner of the arc (
α
＞
180°) , and the tool cannot pass the entrance, No.256 alarm occurs.
