Identification of heat partition in grinding related to process parameters, using the inverse heat flux conduction model

摘要: Abstract Grinding is an abrasive machining process characterized by producing high quality components for added-value industries. Thermal damage undesired phenomenon that may ruin nearly finished products. The study of thermal requires understanding the mechanisms heat partition between wheel and workpiece. In this work original methodology experimental set-up influence grinding variables on to workpiece, Rw, presented. new avoids errors related steep gradients typical operations. addition, uncertainty actual area contact suppressed thanks a rigid controlled configuration. An inverse model based Levenberg–Marquardt algorithm finite element has been used workpiece identification. Results have lead time-dependant Rw definition which had not previously proposed in literature, they allowed as well relating variations values physical removing grinding. validated means indirect parameter: hardness variation during tests, strengthens validity results.
