Title: Innovations of Stephen Roger Coverdale
Introduction
Stephen Roger Coverdale is a notable inventor based in Shipley, GB. He has made significant contributions to the field of grinding methods and machinery, holding a total of three patents. His innovative approaches have enhanced the efficiency and effectiveness of crankshaft grinding processes.
Latest Patents
One of Coverdale's latest patents is a crankpin grinding method. This method utilizes computer-controlled wheelfeed and headstock drives to grind a crankpin of a crankshaft. During the final grinding step, the cutting force is maintained on the wheelhead to keep the wheel and pin under a moderate constant load. This technique helps prevent bounce and chatter marks on the surface of the pin. The rotational speed of the headstock drive is typically reduced to a range of 1 to 5 rpm during this final step. Additionally, the wheelfeed is adjusted to remove a sufficient depth of material in a single rotation of the crankshaft, ensuring the crankpin reaches its finish size.
Another patent focuses on grinding methods and apparatus. This innovation reduces the time required to grind a workpiece by selecting a grinding wheel whose width is not excessively greater than necessary. The grinding machine disclosed in this patent features a wheelhead with a grinding wheel that meets structural and strength requirements. It also includes programmable indexing means to adjust the relative positions of the wheelhead and workpiece, allowing for a series of plunge grinding steps. This optimization enhances the total cycle time for grinding.
