A. Effect of Workpiece Velocity 5 workpiece velocities, which are common in performing a grinding process [3], [10], were used: 0.02, 0.05, 0.13, 0.26, 0.4 m/s. It was assumed that the depth of cut and grinding environment are the same for these different workpiece velocities. Therefore, depth of cut equal to 0.02 mm and
The grinding process is a geometrical undefined cutting process due to the undefined number and geometry of cutting edges interacting with the workpiece. The load on the workpiece as well as the load on the grinding wheel is a result of the programmed actuated variables, the cutting tool properties, and the workpiece properties.
