Abstract

The surface quality of a machined product is a very important consideration in determining process parameters. Due to the inherent nature of the machining process, there always exists a certain amount of residual stress in the material after machining. This paper presents the results of the surface interrogation of machined workpieces by using an x-ray diffraction technique. The machining tests were performed with 4140 hot rolled steel at two speeds. During the tests, tool wear and surface finish were measured and compared to the measured residual stresses. The results show that the x-ray diffraction technique provides valuable information regarding the machining process and if used as an in-process monitoring method could provide a sensing technique for intelligent processing of materials.
