Detailed Thermo-Kinematic Analysis of Face Grinding Operations with Straight Wheels

Abstract

This paper presents a new model that relates thermal aspects with process kinematics in face grinding applications with straight wheels. Changes in chip thickness along the contact area were considered in the model, which allows for taking into account local thermal effects. The model was validated through grinding tests conducted with conventional alumina wheels. Power signals were used as input for the model. Thermal damage on the ground surface was detected using eddy current technology and revealed by acid etching. Both the model and experimental findings provide the basis for developing an approach for process optimization.

Numerical and Experimental Advances in Innovative Manufacturing Processes

“…In [4], phenomenological anisotropic yield functions, which are still the most cost-effective way to predict the elastoplastic behaviour of complex anisotropic metallic sheets, were revisited in the context of hydrodynamic deep drawing. Returning to cutting and machining related techniques, innovative insights into the grinding process were studied experimentally and numerically, respectively, in references [5,6]. Hahn and Tekkaya [7] addressed both the numerics and experiments regarding the use of Vaporizing Foil Actuators (VFA) as an innovative and extremely fast sheet-metal forming methodology.…”
