Conventional Grinding - an overview ScienceDirect Topics

The result with conventional grinding is poor surface texture and parts that break easily. This led to research to determine permissible cutting depths to avoid such problems. It was shown that plastic grinding behaviour can be achieved at very small cutting depths employing very fine abrasive. This is the basis for ultra-precision grinding.
