Define Cutting Parameters - Depth of Cut

It is the thickness of metal removed by grinding wheel in one traverse stroke (lengthwise)

t=depth of cut

 =D₁-D₂ / 2

            Where D₁=Diameter of work piece before grinding

                        D₂=Diameter of work piece after grinding.

In finish grinding depth of cut is taken as 0.005 to 0.015 mm per stroke. Other conditions being equal the best surface finish is obtained in grinding with higher speeds of wheel rotation, lower rates of traverse, and smaller depths of cut.
