Abstract

Successive development of new difficult-to-machine materials requires the adaptation of new efficient methods of their treatment, especially in finishing machining stage, which are of great importance in manufacturing processes. One of the most common finishing treatments is grinding. In order to increase the efficiency of the grinding process and improve the quality of the surface finish, it began to produce grinding wheels with varied granulation. The following article presents the results of a reconnaissance research of the grinding process in which multi-granular grinding wheels made of green silicon carbide were used. The purpose of the experimental research was to investigate the influence of input parameters on surface roughness parameters. The workpiece material used in the present investigation was Inconel 718. The study was carried out with an experimental methodology design. Input parameters were: cutting speed Vc, cross feed rate Fp, longitudinal feed rate Fw. In order to characterize the surface texture after grinding process, surface roughness St and Sz parameters were described. Using the obtained results, statistical models of the grinding process were developed, which will enable selection of the most favorable processing parameters depending on the quality of the surface finish.
