The paper concerns computer modeling and simulation of the roller burnishing process. An application was developed in the ANSYS/LS-DYNA software for the time-dependent simulation of physical phenomena occurring in the contact zone between the burnishing element and the workpiece. The influence of tool penetration on the induced stress and strain state, as well as the distribution and values of temperatures, was investigated. Exemplary results of numerical simulations are presented.The purpose of parts and their operating conditions determine the requirements regarding surface quality, the state of the surface layer, and dimensional and shape accuracy. Current trends in machine construction and operation require products to be characterized by very high reliability and predictable durability. It is necessary to search for and develop such machining methods that enable the conscious shaping of the required properties of the surface layer. The aim of the work is to develop a thermal model of the roller burnishing process.
Surface burnishing is one of the finishing methods for metals, their alloys, and sinters. (…)
