Abstract

Thermal always has significantly effect on the high speed machine tools. When temperature growing up, it often causes processing errors and further reduces product quality. This paper aims to investigate the magnitude of heat sources and temperature distribution in a horizontal lathe based on inverse method. In present thermal model, there is not only consideration of spindle but also analyzing relative structures. The simulation and experimental temperatures are used to predict the heat source as well as temperature field. Effects of speed, number measured points, measurement errors and measured distance on inverse results are analyzed. Results indicate that the inverse method can accurately estimate the heat sources based on two measured temperatures at front and rear outer rings. The inverse results also validate through measured load rate. The results herein is useful information for designing horizontal lathe spindle and reducing thermal errors.
