Study on Temperature of WC-Co Coat in Interminttent Grinding with Cup Wheel

doi:10.3969/j.issn.1000-1093.2012.04.005

Abstract

Abstract: The temperature of coated workpieces in intermittent grinding with cup wheel is investigated. The effective width of moving heat source is calculated under the condition of plane grinding with cup wheel; the shape of grinding block is simplified in order to use traditional heat source model; triangular and rectangular models are analyzed and compared. Energy partition ratio is analyzed on the basis of actual end-face temperature and one-dimensional heat conduction model, and the energy partition ratio is also obtained under different parameters. The feasibility of the temperature model is verified experimentally, and the influence of grinding parameters on the grinding temperature is also analyzed. The analysis results show that the grinding temperature rises with the increase of grinding depth, work-piece feed speed and wheel linear speed.

Key words: machinofature technique and equipment, intermittent grinding, cup wheel, coating material
