Study into the Effect of Crude Palm Oil (CPO) as a Cutting Fluid on the Surface Finish and Roundness During Lathe Cutting Operation

Cutting fluids are widely used in machining either as a lubricant or coolant. In supporting green machining concept that concern on environmental effect and health problem, vegetable oils are finding their way as lubricant for industrial and transportations applications.The first two objectives of this project are to be able to study the effect of crude palm oil (CPO) on the surface roughness and roundness of stainless steel workpiece. CPO is used as cutting fluid during turning operation. The turning operation also involve the dry cutting and turning with Solkut. After turning, the roughness and roundness of workpiece are measured using Mahr Perthometer Concept-Surface Profiler and Mitutoyo Round-Test Machine respectively
