DEVICE FOR CONFIRMING CUTTING OF WORKPIECE, SYSTEM FOR CUTTING WORKPIECE AND METHOD FOR CONFIRMING CUTTING OF WORKPIECE

摘要

PROBLEM TO BE SOLVED: To surely confirm whether cutting of a rod material is complete or defective while damage to a device is avoided.;SOLUTION: A control device 3 (a device for confirming cutting of a workpiece) is provided which is used for a cutting apparatus 1. The cutting apparatus includes: a pair of front main shaft 21 and a rear main shaft 23 that are arranged oppositely in the axial direction and can synchronously rotate around the shafts while each holding one workpiece W; and a cutting tool 25 that cuts the workpiece W clamped by the pair of front main shaft 21 and the rear main shaft 23, into a workpiece body part W1 clamped by the front main shaft 21 and a workpiece cut part W2 clamped by the rear main shaft 23. The control device 3 includes: a position detecting section 35 which detects the position of the workpiece body part W1; and a condition discriminating section 39 which discriminates cut state of the workpiece W using a position of the workpiece body part W1 detected by the position detecting section 35 and detected when the rear main shaft 23 moves in a direction receding from the front main shaft 21 while clamping the workpiece cut part W2, in a state in which the workpiece body part W1 is released by the front main shaft 21.;COPYRIGHT: (C)2013,JPO&INPIT
