Ecological aspects of the cutting fluids and its influence on quantifiable parameters of the cutting processes

This contribution gives an analysis of the ecological parameters of the cutting fluids and its influence on the machinability parameters. Evaluation of quality parameters of the cutting fluids is based on output parameters of production process considering also ecological norms. Some results of machinability tests, which were done in tapping threads into standard reference steel C 45 E4 and Al-alloy AlMgSiPbBi for free cutting show how it is possible to achieve acceptable machinability parameters by use of new environment-friendly cutting fluid. The cutting parameters were chosen from the technological database with respect to particular machined material/cutting tool combinations. This approach has been used to quantify the performance of the existing products, compare products in the marketplace, and search for novel cutting aid additives. (C) 2001 Elsevier Science B.V.
