Abstract
A cylindrical engraving system selectively able to engrave in a helical and a 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.
Claims22
A method for engraving a cylinder comprising the steps of:
- (a) helically engraving a helical pattern on said cylinder;
- (b) cylindrically engraving a cylindrical pattern on said cylinder;
- and
- (c) controlling an engraving head to perform said steps (a) and (b).
An engraving system for engraving a helical pattern and a cylindrical pattern on a cylinder comprising:
- an engraving head mounted on a carriage;
- a cylinder support for receiving a cylinder;
- a driver for driving said carriage;
- and
- a controller coupled to said engraving head and said driver for energizing said driver and said engraving head to helically engrave a helical pattern on said cylinder and also to cylindrically engraving a cylindrical pattern on said cylinder.
