He has made significant contributions to the field of machine tools, particularly with his innovative designs that enhance manufacturing processes. With a total of two patents to his name, Griffiths continues to push the boundaries of technology in his industry.
Latest Patents
Griffiths' latest patent is a computer-controlled grinding machine. This advanced machine is programmed to control the grinding process by calculating the wellhead demand positions. It takes into account the difference in height between the workpiece axis of rotation and the grinding wheel axis of rotation to produce a height-adjusted value for P. The equation used to compute the position demand values for a crankpin of a crankshaft is as follows: P = (T*cos A) + (R + r) - ((T*sin A) + H). In this equation, P represents the height-adjusted demand position of the grinding wheel at each instant, while R is the current radius of the grinding wheel, r is the target radius for the crankpin, T is the throw of the crankpin around the main crankshaft axis, A is the angular position of the crankshaft relative to the start position, and H is the vertical height between the two axes. The value for P is typically calculated for each of 3600 angular positions during one revolution of the crankshaft.
