This study deals with on-machine resharpening of cutting tools for the purpose of reducing the consumption of scarce materials and suppressing the total production time on precision machining. To make the resharpening processes on machine automatically, the processes must be fast and its apparatus must be simple. So the conventional methods like grinding or PVD coating can't meet the requirements. Electrodeposition of composite coating is one of the methods which meet the requirements. Ni-P-SiC composite coating layer on cemented carbide tool was able to cut steel. Then, by electrolytic etching with H_2SO_4 electrolyte, Ni-P-SiC on cemented carbide is removed at the rate of 20μm/min or faster and the oxidative reaction stops by itself result from that cemented carbide forms passive state layer. Using these coating and stripping methods, resharpening process takes within only 5 minutes.
