Dry grinding process with workpiece precooling

This paper proposes a workpiece cooling prior to grinding in order to allow a dry processing. Tests and simulation showed good potential. The obtained part quality is good, and there is no thermal damage since there is a higher heat flux from the grinding zone to the workpiece due to the much lower temperature of the last. The process design is a key task for good results and should include a precise determination of the cooling conditions that allow the grinding cycle heating to bring the part temperature close to the environment at the end of spark-out.
