Transcribed Image Text:

In traverse surface grinding of a steel workpiece, 3 inch by 6 inch by 9 inch large, as shown in the following figure, the 90 grit aluminum oxide grinding wheel has a diameter (D) of 6 inches. The cross feed (f) used is 1/3 inch, the radial depth of engagement (a,) is 1/32 inch, the spindle speed is 3200 rpm, and the traverse speed (vera) is 1 in/s. In this case the grain aspect ratio, r, is 4. a. Determine the total time needed to grind one flat surface (t). b. Determine the material removal rate (Z). c. Calculate the surface roughness R.. radial depth of engagement traverse ap velocity feed In traverse surface grinding of a steel workpiece, 3 inch by 6 inch by 9 inch large, as shown in the following figure, the 90 grit aluminum oxide grinding wheel has a diameter (D) of 6 inches.
