ABSTRACT

The main requirement of the desired machining process is obtaining high material removal rate, good surface quality and low tool wear rate because it has a direct impact on production cost. Appropriate cooling conditions during the machining process can lead to reduce costs and increase efficiencies. Machining of stainless steel materials are known to be very difficult because it has the properties such as gummy, high tensile strength and high ductility, high fracture toughness and modulus of elasticity, high work hardening rates and reactivity at high cutting speeds with most tool materials.

Research proposal is intended to evaluate the cooling conditions are suitable for the material austenitic stainless steel AISI 316L (American Institute Standard Industries 316L). This material is widely used for the purpose of implantation in orthopedic surgery. Cooling techniques to be used involves dry cutting, near dry cutting and wet cutting using coated and uncoated carbide tools.

During the experiments the tool wear, cutting force, chip formation and surface roughness will be measured for each variation of cooling and cutting conditions.
