This paper describes a force model for grinding with segmental wheels. Both experimental and analytical results show that average grinding force decreases and peak force increases using segmental wheels as compared to conventional wheels. Larger spaces between segments further reduce the average force and increase the peak force. The reduction in average force is due to the size …
【Abstract】 A new simple model of grinding force in surface grinding is proposed in this paper.The model is based on the fact that the grinding forces are composed of chip formation force and sliding force.The formula for calculating the tangential and normal grinding force per unit width is obtained based on the classical formulas.The coefficients in the formula are determined ...
