Appl. No.:

6/108338

Inventors:

Ronald J. Gordiski - Ansonia CT
Robert G. Bennett - Seymour CT
Alfred T. Parrella - Newtown CT
Michael Bagnall - Southbury CT

Assignee:

USM Corporation - Farmington CT

International Classification:

G05B 1918
G06F 1546

US Classification:

364475

Abstract:

A digital control system is provided for positioning a tool relative to a workpiece. The tool is preferably a grinding wheel and the workpiece is a roll appropriately mounted within a roll grinding machine. The digital control system receives various infeed commands representative of the different types of infeed positioning that are to be performed during a grinding operation. The digital control system is thereafter operative to combine these infeed commands into a composite set of control signals. These control signals are applied to a single motor within a pivotal infeed arrangement which moves the grinding wheel relative to the workpiece.

International Classification:

B24B 5100

US Classification:

5116587

Abstract:

A digital control system for a roll grinding machine controls the infeed of the grinding wheel in a manner which minimizes the impact of momentary changes in infeed command. The momentary change in infeed command which is effectively controlled is that of a pulse compensation introduced for the wear of the grinding wheel.
