Title:
GRINDING CONTROL METHOD AND DEVICE FOR GRINDING MACHINE
Document Type and Number:
Japanese Patent JP3710575
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To determine a cut retreat amount, eliminate worsening of work efficiency, so that accurate stable work can be realized, and simplify a device constitution, taking into consideration a change of grinding wheel sharpness and a response delay of a mechanical system and an electric control system.
SOLUTION: A device is applied to a grinding control method of a grinding machine in which when rough grinding work is completed, cut retreat is performed, thereafter so as to perform finish grinding work, a depth of cut is controlled. While measuring a prescribed item relating to a workpiece and the grinding machine during rough grinding work, by this measured value, and amount of cut retreat, which must be performed, is calculated. When the rough grinding work is completed, cut retreat is performed by the calculated cut retreat amount. The device is constituted by an NC cut control device 21 and a measuring control device 22 calculating the cut retreat amount. In the NC cut control device 21, during the time a cut of rough grinding work is performed, an external input of the cut retreat amount xbo is always supervised, and a preset cut retreat amount is rewritten.
