Applying pneumatic probe system to monitor part’s surface roughness and grinding wheel’s wear in profile grinding for ball bearing’s inner ring groove ☆

The article presents the results of research and apply pneumatic measuring probe to monitor part’s surface roughness and grinding wheel’s wear in profile grinding for the ball bearing's inner ring groove. On that basis, it makes an online warning for limiting dress grinding wheel according to the given surface roughness threshold or wear threshold. The signals obtained from pressure sensors of pneumatic measuring probe system are processed to calculate grinding wheel’s wear and part’s surface roughness. The output values of this probe system is very close to experimental data values. The results demonstrate ability to monitor the real status of grinding wheel’s wear and part’s surface roughness.
