+ T, T are grinding wheel thickness, then are determined as that the laser beam of laser displacement sensor is beaten on certain abrasive particle of grinding wheel cylindrical, at this moment instead
Machine tool controller is fed back to, emery wheel micron accuracies are fed, if after going beyond the scope, in return a bit, until precision controlling is at 2 μm
Within, click on after confirming, complete to knife process；3）If L>L0+T, then be determined as the laser beam of laser displacement sensor
Emery wheel is crossed, at this moment machine tool controller is fed back to, it is necessary to which emery wheel is back to a coordinate, until searching out the maximum of emery wheel
Coordinate value at diameter, finally takes optimal solution；（5）According to the coordinate value at the emery wheel maximum gauge searched out, setting lathe
To knife starting point, i.e., the starting point contacted as the emery wheel of grinding program with workpiece.
The step（1）Described in lasing beam diameter be not more than the 1/3 of abrasive grain diameter.
The step（2）Described in laser beam beat in grinding wheel cylindrical edge at 1~2mm.
One kind tracks method emery wheel setting system, including emery wheel on main shaft and fixation or is built in swashing on lathe
Optical displacement sensor, laser displacement sensor is located at the axial direction of emery wheel, and laser displacement sensor is by emery wheel and laser displacement
The relative position information of sensor feeds back to the method system software that tracks, and the method system software of tracking is made will judge to tie after calculating judges
Fruit feeds back to machine tool numerical control system, machine tool numerical control system control emery wheel movement.
The beneficial effects of the invention are as follows：Using laser displacement sensor, the quick tool setting during wheel grinding is realized, is adopted
With this new method can improve emery wheel to knife precision and efficiency, it is to avoid emery wheel disfiguring workpiece, can by half an hour even it is several small
What Shi Caineng was completed works knife, completion in 1-3 minutes is shortened to, so as to significantly improve accurate grinding processing efficiency；Can be
It is rapid on high speed grinding machine, be exactly found emery wheel to knife starting point, improve the precision and efficiency of high-speed grinding.
