In this study, a method to measure workpiece size errors due to grinding wheel wear for NC grinding machines and their compensating method are proposed. In this method, workpiece size errors are measured using the contact signals between the grinding wheel peripheries and a single point diamond dresser in the dressing process, and using an NC dressing program, the worn parts of wheel peripheries can be distinguished from other parts by on/off signals of an AE sensor located behind the dresser. According to the experimental results, it is shown that workpiece size errors can be identified in the resolution corresponding to the least incremental input of NC signals using the NC machine. Furthermore, applying the relationship between AE signals and workpiece size errors, a new automatic workpiece sizing cycle is proposed, and its usefulness is experimentally confirmed.
