In this research, CNC tool grinding system has been developed with open architectural PC-NC kernel. The developed 4 axis tool grinding system is motion-controlled by PC-based controller. To reduce the machining error, machine vision system is adopted. By using the various image processing algorithms, alignment and auto-setaup processes are achieved between grinding wheel and workpiece. Also, the resolution of machine vision system is improved 10-15 times with the process of image enhancement and noise reduction. In grinding mechanism, there exist numerous parameters especially in machining conditions and processes. It is a very hard work to decide the optimal machining parameters. In this work, to optimize the grinding conditions, the grinding force has monitored using hall sensor. Since the hall sensor signal from the spindle current represents the grinding force, the excessive grinding force occurred at comer could be stabilized by feed rate control. In grinding process, as the wheel wear is natural phenomenon with its self-sharpening action, it is exceedingly difficult to measure the wear width during grinding process. The tracking method was developed with machine vision system. This algorithm enables the system to measure the wear width during grinding process. It is very useful to compensate the wheel wear in real-time.
