The efficiency of hard machining processes

Abstract

The machining of hardened surfaces has increased significantly in the past years. While abrasive machining has held the lead up to now, the productivity of cutting by single-point tools is improving. In this paper the machining efficiency of surfaces of identical quality according to R z and international tolerance (IT) class was analysed after machining by various procedures: traverse bore grinding; hard turning by standard insert; and a joint procedure by standard insert in the hard turning operation. Based on an analysis of the material removal rate (MRR), environmental load and flexibility of machining, the procedures were ranked and recommendations were made for their application area considering the running conditions. It was found that the MRR is most favourable in the hard turning version. However, if the running conditions of the built-in part require a random topography, the most efficient version is the joint procedure.

Preliminary Study On the Function-Defining 3D Surface Roughness Parameters in Tangential Turning

“…The calculated averages were used to determine equations, which are capable of calculating and further analyzing the studied 3D roughness parameters. The 2 3 full factorial design methods were applied to work out these. For each studied parameter the required coefficients are calculated.…”

Optimization of Material Supply in Smart Manufacturing Environment: A Metaheuristic Approach for Matrix Production

“…Why is so much effort being put into this research? Conventional production environments have been transformed into cyber-physical production, and this new production environment needs more attention both from a technology [61] and logistics point of view. A comparative table contrasted the proposed methodology in front of related analyzed research works, where the relationship between this solution and past literature was discussed.…”
