Thermal State Visualization of Machining Workpiece by Means of a Sensor-Configured Heat Conduction Simulation

Abstract

This paper deals with an adaptive visualization method of the thermal state in machining operation. The visualization is expected to enhance the recognition ability of operators. First, a framework of thermal state visualization is proposed. Then, a sensor-configured heat conduction simulation is proposed as an estimation method of thermal states of the machining workpiece. The method is based on the association of sensed data with the process simulation. As an implementation of the proposed estimation method, a prototype system is developed. After illustrating the configuration of the prototype system, results of a simple example are shown. The results indicate the effectiveness of the adaptive estimation. The influence of measurement points are also evaluated based on the case study. Finally, conclusions and future works are presented.
