Cooling and Machining Strategies for High Speed Milling of Titanium and Nickel Super Alloys
Proper selection of machining parameters, cooling strategies, and machining methods in high speed machining of difficult-to-cut metals like titanium and nickel super alloys is of significant importance to enhance their machinability, productivity, and decrease cost. These difficult-to-cut metals pose serious difficulties during their machining like high heat generated at the cutting zone as a result of high friction between chip/tool/workpiece interfaces, which is not extracted rapidly as is generated due to their low thermal conductivity. Thus, most of the heat generated stays at the cutting zone causing severe tool wear, large cutting forces, and tool failure. This chapter will introduce the reader to the latest research/case study on the effect of machining parameters, milling methods, and cooling strategies on machinability during high speed machining of titanium alloys and nickel super alloys. The work described in here is a result of series of research conducted in the Computer Numerical Control (CNC) and Virtual Manufacturing Laboratory, Department of Mechanical and Aerospace Engineering at Missouri University of Science and Technology, Rolla, Missouri, United States. The aim of this chapter is to provide useful information to researchers, professors, graduate students, and practicing engineers or production managers working in high speed machining area. Their application will lead to environmentally friendly, cost-effective, and sustainable manufacturing.
