Grinding Force of Cylindrical and Creep-Feed Grinding Modeling

This chapter presents an experimental study of grinding forces as relationship of workpiece speed v, feed rate sa and depth of cut a. For the modeling of cylindrical grinding used was response surface methodology and genetic algorithms. Modeled was the tangential force Ft and the normal force Fn in cylindrical grinding. The process included measurement of cutting forces during cylindrical grinding and later calculating their values using abovementioned techniques and determined adequate models. This chapter also examines the value and character of cutting forces in the creep-feed grinding. In order to identify the impact of cutting forces on the state of the process of creep-feed grinding, according to the elements of the machining experimental tests, relationship of the tangential and normal components of the grinding force and ratio of grinding force were determined. In comparison with the traditional multi-pass grinding results, the occurrence of higher cutting forces in creep-feed grinding, especially normal components, is shown
