Chip loading on electroplated diamond wheels in trimming process for CFRPs and effects by in-process laser dressing

Abstract

An excellent machining performance of electroplated diamond wheel is suitable for trimming process of CFPRs (carbon fiber reinforced plastics) where unnecessary portions of material are cut off. However, chip loading is one of serious problems caused with grinding wheels during the process. In this study, through the experimental investigation under various conditions, it is demonstrated that machining conditions determine the degree of chip loading on the wheel. Experimental results show that the chip loading immediately reaches at very early stage of process and is obstructive to the continuous trimming process. In addition, an in-process laser dressing is proposed as a solution to suppress and the chip loading and to enable highly efficient machining of CFRPs. Influences of laser irradiating parameters are investigated and the feasibility of proposed method is examined.
