Thermal and mechanical modeling during dry turning operations

As assumed by ISO 14000 environmental management norms, machining performance concerns also environmental issues. Dry cutting is one of the objectives of many manufacturing development projects: by reducing industrial wastes, costs should be reduced. But dry cutting changes thermo-mechanical interactions between workpiece, tools, and chips. These changes could produce damages on workpiece quality. In order to prevent these issues, this paper propose a new approach to predict cutting temperature in dry turning by using an analytical model of thermal distribution on the workpiece surface subject to a rotating heat source. This modeling is validated by several experimental tests on AISI 1040 Steels.
