Machining Waste Streams

Heat Page

All machining processes create and transfer heat, primarily through friction and plastic deformation. This heat is of concern both to the manufacturing engineer, who is concerned about the effects of heat on the process capability, and to the environmental engineer, who must look at all environmental effects from the process.
Heat buildup in cutting will speed the erosion mechanisms in tools, and will cause deformations in the workpiece, which may increase scrap rates. Thermal cycling, that is, rapid heating and cooling, is a concern with interrupted cutting. This effect may cause great harm to tools, the machine tool, and the workpiece. Heat generation can also cause cutting fluids to increase their evaporation and breakdown rates, and to actually cause fires with flammable and semi-flammable cutting fluids.
