effect of grinding wheel wear on the rake angle of taper ball

Tool bit - Wikipedia

Back rake is to help control the direction of the chip, which naturally curves into the work due to the difference in length from the outer and inner parts of the cut. It also helps counteract the pressure against the tool from the work by pulling the tool into the work. Side rake along with back rake controls the chip flow and partly counteracts the resistance of the work to the movement of ...

This feature ...
