Abstract

It is essential that the CO2 emissions produced by metal cutting manufacturing are reduced due to global warming. Metal cutting is an essential aspect of modern manufacturing, and accounts for approximately 70 percent of world metal manufacturing. Reductions of CO2 can be shown to be possible when machining at high cutting speed, when using tungsten coated tool tips. The addition of air-cooled with the addition of a small amount of vegetable oil, also allows high cutting speeds to be used. In addition to the cutting speed the tool paths and depth of cut are examined to determine their effect in reducing the CO2 emissions. A machining conditions model, reducing the environmental burden for machining operation is proposed based on this research. Two Numerical Control (NC) programs that produce a simple shape are evaluated, to show the feasibility of the proposed operating conditions model.
