ABSTRACT:
A computer controlled grinding machine grinds a cylindrical region and an annular shoulder of a rotatable workpiece. Relative movement is effected between the workpiece and a grinding wheel along a line of action which subtends an angle of approach of less than 90 degrees to the Z axis of rotation of the workpiece. Such an angle of approach enables the wheel to grind the annular shoulder of the workpiece simultaneously with grinding the cylindrical portion.
