Comprehensive analysis of the thermal impact and its depth effect in grinding

The focus of this work is the analysis of the thermal impact and its depth effect in different grinding processes. The investigated processes cover different
kinematics and thus broad ranges of the relative speeds and the intensities of the moving heat source regarding the ground surface. A uniform lower
process limit characterizing the onset of grinding burn for the different kinematics is identified by means of the specific grinding power and the contact
time. The experimental results together with the theoretical considerations of peak temperatures lead to the conclusion that the process specific range of
the contact time is mainly responsible for the thermal depth effect. The results enable the targeted exceeding of the critical process limit in roughing and
the subsequent correction by finishing.
