Abstract
A grinding machine uses a conical grinding wheel (10) to create a non-circularly symmetric surface (defining, for example, a re-entrant cam) on a workpiece. The machine is operable to rotate such a workpiece about a first axis (5) and the machine has drive means for rotating the conical wheel about a second axis (14). A feeding mechanism brings the wheel into contact with the workpiece to define a line of grinding where the wheel contacts the workpiece (i.e. a cutting line). In use, a rocking movement is imparted to the wheel and spindle relative to the workpiece as the latter rotates so as to maintain the orientation of the cutting line relative to the first axis and of the second axis relative to the cutting line.
