The Future Role of Metalworking Fluids in Metal Cutting Operations

摘要

The case for establishing viable methods of reducing cutting fluid consumption, through their replacement by gaseous coolants is presented. This paper formed the basis of significant research presented in Stanford’s other outputs. The industrial interest that evolved during the work is driven by many factors including environmental considerations: fluid disposal can result in the accumulation of dissolved nitrogen compounds causing eutrophication of ground and surface water; incineration forms nitrogen oxides and carcinogens in the form of dioxins; and cost, in that the use and disposal of cutting fluids forms 17% of the cost of cutting operations.
