    • 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.
    • 要解决的问题:确保确保杆材料的切割是否完整或有缺陷,同时避免了对设备的损坏。 解决方案:提供一种用于切割装置1的控制装置3(用于确认切割工件的装置)。切割装置包括:一对前主轴21和后主轴23, 沿轴向方向相反地设置,并且可以同时围绕轴旋转,同时保持一个工件W; 以及切割工具25,其将由一对前主轴21和后主轴23夹持的工件W切割成由前主轴21夹持的工件主体部W1和被后主体夹紧的工件切割部W2 控制装置3包括:位置检测部35,其检测工件主体部W1的位置; 条件识别部39,利用由位置检测部35检测出的工件体部W1的位置,检测到工件W的切断状态,并且在后主轴23从前主轴21退出的方向上移动时进行检测; 在工件主体部分W1被前主轴21释放的状态下夹紧工件切割部分W2。(C)2013,JPO&INPIT
