The geometrical surface generation is simulated for the grinding process with the grinding speed ranging from 25 to 1000 m/s. The effects of work speed, depth of cut, spark-out cycles, and cutting edge density etc. on the surface profile and the surface roughness are investigated. The three-dimensional surface profile generated by the cutting edges is described geometrically for each cross section of the workpiece which is perpendicular to the direction of grinding, considering the distribution of the cutting edges in a grinding wheel. The simulated results are displayed on the CRT by the computer graphics, and the surface roughness is also estimated theoretically. As the results, the following conclusions are obtained: (1) The high-speed grinding reduces the surface roughness, comparing with conventional grinding. (2) The work speed and the cutting edge density have little influence on the surface roughness in the high-speed grinding. (3) Relatively good surface roughness can be obtained by the high-speed grinding with a few spark-out cycles, regardless of pre-surface roughness.
