Title: Griding defect prediction device
Inventor: ISOGIMI SATOSHI
IPC: B24B49/10
Filed: 2020-03-23
Abstract: To provide a grinding defect prediction device which can predict that a surface roughness of a work-piece deteriorates and shape collapse thereof occurs during grinding, and can improve grinding yield.SOLUTION: This grinding defect prediction device comprises a processing defect prediction part 58 which predicts processing defects during grinding on the basis of a change in a first signal strength SP1 in a first frequency band B1 relating to crashing of abrasive grains 38 of a grinding wheel 14, or a change in a signal strength ratio SR(=SP1/SP2) of the first signal strength SP1 to a second signal strength SP2 in a second frequency band B2 relating to friction vibration or elastic vibration that occurs by contact between the abrasive grains 38 of the grinding wheel 14 and a work-piece 44. Therefore, the prediction device can predict processing defects for grinding of the work-piece 44 prior to deterioration of a surface roughness of the work-piece 44 during grinding. Thus, it is reduced that the work-piece 44 during grinding becomes a defective product, and therefore, grinding yield can be improved.SELECTED DRAWING: Figure 1
