Artificial cutting-fluid smoke generation: effect of pressure

Industrial smoke from cutting fluid poses a potential carcinogenic hazard to workers. For toxicity tests, an artificial smoke device needs to be designed. Such a device would be easy to construct if it were known that smoke is a function of heat during cutting processes and not the cutting pressures. Gas chromatograph response was the same for smoke generated with and without pressure. The implication is that smoke generated during a metal cutting process is due to high temperature and is not influenced by the cutting surface pressures.
