Improved Process Control in Camshaft Grinding Through Utilization of Post Process Inspection With Feedback

af Timothy Dalrymple

Abstract: In order to take full advantage of the introduction of computer numerical control technology in camshaft grinding and post-process inspection, a closed loop control scheme is proposed. This strategy makes use of post-process inspection results to modify the commanded part geometry used in the grinding program. The commands are modified in order to minimize the lobe contour and relative timing errors. It is shown that using a control strategy comprised of feedforward and feedback elemen... (Læs mere)
