Comparative method of thermovision temperature measurement in single-pass internal cylindrical grinding

This paper presents the results of thermovision temperature measurement in the contact zone of grinding wheel and workpiece during single-pass internal cylindrical grinding process. Such a kinematic form of grinding process is characterized by very difficult machining conditions. In order to control grinding temperature in this process, the authors developed a special measurement method which enables the usage of thermovision camera. The essence of a new method and the results of investigations were presented. In tests, the influence of abrasive grain kinds (alundum 99A, sintered corundum SG) and their size (46, 60) on grinding temperature was determined.
