Advanced Thermal Measurements of Modern Manufacturing Systems

− The paper presents some new measurements and instrumentation paying a special attention to the thermal behaviour of modern manufacturing systems. Acording to a CIRP evaluation, more than 50% of the machining errors, even in the case of modern machine tools, are due to the thermal phenomena. The study of thermal behaviour for machine tools is very important for precision processing, e.g. grinding. The problem is more complicated due to thermal field variations in space and time. The studies and the tests carried out (the thermography used by the author for the first time in Romania) were focused on the optimization of the Romanian grinding machines with the scope to achieve a better quality. The paper presents the author’s results some of them carried out at the Technical University of Cluj-Napoca, Romania, and other at the University of Stuttgart granted from the NATO Science Programme.
