Effect of Lubrication Condition on Surface Roughness in Facing Operation

Mechanical Engineering

Smooth surface and lower friction is the first and foremost thinking in modern manufacturing process. So, after facing operation a smoother surface is first requirement. During facing operation high friction increases the temperature at high level. Such high temperature causes various problems like a high tool wear, large heat affected zone, change in hardness and microstructure of the work piece, burning and its consequence and high surface roughness. Application of conventional cutting fluids reduces the above problems to some extent through cooling and lubricating of the facing zone. But its result changes with the change of cutting fluid utilization and change of the cutting speed. In this research work different amount of cutting fluid is used and its effect on the surface roughness has investigated for the three different materials like mild steel, aluminium & cast iron. The facing operation was done for a constant spindle speed and other parameter like feed rate kept constant for dry, semi dry and wet machining. The experimental results reveal that lubrication condition during facing operation effect roughness of those metal surfaces. The optimum cutting fluids lead to economical benefit and environmental friendly machining.
