Abstract: For further study the evolvement rule of grinding temperature in camshaft high speed grinding, a testing device of workpiece surface temperature in camshaft high-speed grinding was designed based on infrared thermal imager.The orthogonal test method and single factor method were applied to design of experiments. Grinding temperature experiments were carried out under different grinding process parameters, and the range method and variance method were used to analyse the influences of grinding process parameters on the grinding temperature. The feasibility of high speed and high efficiency grinding based on workpiece surface temperature and surface roughness were analysed. These experiments provided reliable evidence to solve the problems of camshaft grinding surface thermal damage.

Key words: camshaft, grinding temperature, infrared thermal imager, multi-factor analysis of variance
