A. The work is reciprocated as the wheel feeds to produce cylinders longer than the width of wheel face

B. The work rotates in a fixed position as the wheel feeds to produce cylinders equal to or shorter than the width of wheel face

C. The work is reciprocated as the wheel feeds to produce cylinders shorter than the width of wheel face

D. The work rotates in a fixed position as the wheel feeds to produce cylinders longer than the width of wheel face
