Thermal Aspects of Grinding: Part 1—Energy Partition

Abstract

An investigation of the thermal aspects of grinding is described in a two paper sequence. This first paper is concerned with the distribution of the total grinding energy among chip formation, plowing, and sliding energy components, and the portions of each of these energies which are conducted as heat to the workpiece. The results indicate that virtually all the sliding and plowing energies, and approximately 55 percent of the chip formation energy, are conducted as heat to the workpiece. In the second paper, these results are related to grinding temperatures and workpiece burn.
