EVALUATING TEMPERATURE IN FACED MILLING OPERATIONS BY INFRARED THERMOGRAPHY

ABSTRACT
Temperature control plays a crucial role from the machining efficiency viewpoint. Measuring cutting temperature in a face milling operation is no easy task because it is an interrupted cutting process, and not much research about this topic appears in the literature. A methodology based on infrared thermography was developed to measure the temperature in faced milling. The influence of cutting parameters and type of material on cutting temperatures was evaluated. The experimental values obtained for cutting temperature corresponded to those expected and according to other authors. It has been established for AISI 304 stainless steel that temperature may increase if parameters that shorten the cutting time are used. This condition does not apply to all materials as such cutting parameters do not have a strong impact on copper and aluminum machining. Experimental values were not necessarily in keeping with the analytical methods described in literature because they did not consider the influence of some parameters like axial and radial cutting depth.
