Grinding-Hardening Experiments and Grinding Force Analysis in Infeed External Grinding for 45 Steel

Abstract:

The grind-hardening method suitable for external grinding is proposed in this paper and the experiments are carried out on MI432B grinding machine.The hardened layer of the workpiece with cut depth 0.3mm and speed 0.2 m/min is analyzed.The result indicates the metallurgical structure of the hardened layer is martensite and the top hardness value is 754 HV(about 620 HRC).At the same time,the grinding force,one of the most important factors of grind-hardening process is modeled, and the measurement method is provided with elastic core clampers.The measurement result shows that the values of both the tangential force and the normal force increase when the cut depth increases,and the top value is 146 N and 656 N with the cut depth value of 0.4 mm respectively.
