Experimental Study Of Thermal Sliding Contact With Friction : Application To High Speed Machining Of Metallic Materials

摘要: In High Speed Machining (HSM), thermomechanical events at the tool‐workpiece interface are strongly coupled. They characterized by extreme conditions of stress and strain as well heating heat gradients that it is advisable to control for a good resolution problem.We present first experimental approach based on friction tests. The similar ones occurring in orthogonal cutting terms pressure nose chip sliding velocity. workpiece pressed tool suddenly moved according selected speed pressure.Experiments carried out with XC38 metallic sample temperature 900 K velocity 0,2 m/s. thermal workpiece‐tool estimated means recordings an inverse conduction method. Finally, flux compared one obtained mechanical way which considers measured coefficient. This comparison ...
