Abstract
Method and apparatus are provided for machining processes involving the generation of frictional heat in which the workpiece is contacted by a coolant whose viscosity progressively increases with decreasing temperature and by a pressurized fluid that, upon expansion while undergoing a reduction in pressure, absorbs heat and cools the coolant and increases its viscosity to provide a consistency that enhances its lubricity to minimize the generation of frictional heat during the machining process while enhancing conductive heat transfer into the machining tool.
