Abstract
Temperature distributions produced at the tool-chip interface were determined for AISI 4140 while undergoing orthogonal cutting operations on a Makino A-55 machining cen-tre (20 thousand RPM/18.5 kW spindle), which was configured as a lathe. Dynamic thermal images were captured by a custom, high-bandwidth (40 Megapixels/sec) and calibrated microthermometry system (~5-micrometer resolution) for a wide variety of machining parameters reaching surface speeds of up to 477 m min-1. Each test was compared with finite element models, and despite modest uncertainty estimates, it is il-lustrated that while simulation software is a reliable means of predicting qualitative trends with respect to cutting parameters, it is not in this case a reliable means for quan-titative prediction of temperatures and temperature profiles.Proceedings Title
