Abstract

PURPOSE:To prevent interference of the tool and the work when machining mode is changed by automatically receding or returning the tool by computing the receding and returning passage of machining mode. CONSTITUTION:The output from NC7 is stopped when tool abnormal signal R1 is sensed at NC7, and the abnormal position is memorized at the actual position memory resistor 16, and the machining completing position at the sequence NO is memorized at the NC instruction position memory resistor 17. With the tool receding position memory resistor 20 provided, the receding position A is the fixed value determined by the installing position of the automatic tool exchanging device 6, and the X axis minimum value (a) and the escaping rate (1) are the values determined by the shape of the work. Then, each value of the resistor is transmitted to the operation circuit 21 to calculate receding and returning mode instructions.
