Abstract
The successive spacing and its distribution of cutting or ploughing edges are experimentally made clear by analyzing interference grooves on ground surface and correlating grooves with positions of cutting edges on the wheel surface. Then discussed are the effects of grinding conditions, such as plunge speed, speed ratio, grain size and dressing condition upon the successive cutting edge spacing. The successive cutting edge spacing distributes widely, following the Gamma Distribution. The successive spacing of cutting edges concerning cutting or ploughing has a close relation to the real interference depth of wheel. The successive cutting edge spacing is not a characteristic value of the wheel, but is affected by grinding conditions.
