SURFACE PROFILE GRINDING SEMIAUTOMATIC MACHINE WITH CNC OSH620F3. Semiautomatic machine is designed for finish grinding of flat surfaces and profiles corresponding combination of sections, straight lines, arcs, circles and other intelligent curves in rectangular coordinate system. Grinding wheel profiling is realized by rotating diamond rollers installed on table by .
surface profile and diameter of the grinding wheel. A very efficient onmachine profile measurement system has been developed based on Coordinate Measurement Machine (CMM) principle to check the ground surface profile during machining. Wheel wear was also measured at some regular interval to find out the latest wheel diameter possible. Tool path in the NC .
