摘要： A cylindrical engraving system selectively able to engrave either in a helical or circumferential format. An encoder scans index markings on the surface of a cylinder being engraved and generates timing pulses for selective application to one or the other of a helical drive unit or a circumferential drive unit incorporated within the system controller, Engraving is performed by an engraving head which is stepped in the axial direction along the workpiece in response to step pulses generated by the selected drive unit. The step pulses may be generated in spaced bursts or at a regular frequency depending upon whether circumferential or helical driving has been selected.
