Modeling and verification of temperature rise during machining

Abstract

The temperature rise in chips during machining process largely affects the tool life as well as the quality of the machined product. It also affects the power required for machining. Therefore, accurate measurement of temperature rise in chips during machining is important not only to understand and predict any changes in the properties of the component but also to predict and optimize the life cycle of the tool. In this work, we measure temperature rise during shaping process of the aluminum block using thermal imaging technique and compare the values with that obtained using Weiner’s model for moving heat source. Our result indicates that temperature value obtained by the infrared camera was very close to those obtained by Weiner model. This work validates the use of Weiner model for an in situ temperature rise of chips during machining.
