DISK-SHAPED EDGED TOOL FEEDING CONTROL METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a disk-shaped edged tool feeding control method and device for implementing the device that can minimize the length of time taken for cutting operation without requiring any detector of starting and ending times of the cutting operation.SOLUTION: In a disk-shaped edged tool feeding control for implementing feed speed PID control using load torque calculated on the basis of electric power consumed by and the rotating speed of an edged tool rotating motor, the position of the disk-shaped edged tool in an X direction immediately before the start of cutting is set in a position displaced by a prescribed minimum fixed distance from a cutting start position; the cutting start and end positions are acquired from the rotational shaft torque of the disk-shaped edged tool; when the remaining numbers of the prescribed cutting rounds during continuous operation and the planned duration are determined at the time of cutting in each round of cutting, the disk-shaped edged tool is shifted in an X axis direction to a position at a preset distance from the position of next cutting start and in a Z axis direction to the position of next cutting start; and a palette to which a work is fixed to the position is shifted to a Y axis position of the next cutting start.SELECTED DRAWING: Figure 1
