High-performance industrial grinding: recent advances and case studies from the automotive engine production

Paper i proceeding, 2016

The development of new high-performance industrial grinding technologies for engine production in the automotive industry is presented. The grinding fundamentals are revisited in view of modeling and simulation to examine the effects of process design on grinding temperatures. The advantages associated with utilization of newly developed temperature-controlled grinding processes are explained via the analysis of process-control strategies. Two research-and-development projects from Scania´s engine-production plant are discussed to illustrate industrial challenges and achieved impacts. Two case studies are presented for (1) cam-lobe grinding and (2) crankpin grinding, demonstrating optimized grinding processes for achieving shorter cycle times and higher quality. Both patent-pending technologies are experimentally validated in actual production and are implemented in existing production lines.
