Today, various industries has increased their demand of miniature components
as time advances. As a result it opens a gateway for researcher towards micromanufacturing in the field of aerospace, nuclear, telecom and biomedical
sector. Nickle-based alloys possess high tensile strength, strong corrosionresistance and low thermal conductivity having sufficient use in a wide range
of temperature application. These alloys are considered as difficult-to-machine
material for their low machinability rating. In this research Inconel 600 was
selected as workpiece material. Micromachining were performed upto 20 mm
length with different combination of machining parameters like feed/tooth,
cutting speed, depth of cut, and cooling conditions using orthogonal L9 array.
Two-flute, un-coated Tungsten carbide cutter of 0.5 mm diameter were used in
experiment. Results were analyzed through analysis of variance to see
influence of these parameters on burr generation, tool flank wear, and surface
roughness. Results shows that small DOC, high feed rate and high cutting
velocity at dry condition results small burr formation with compromise on
surface quality and tool wear. Similarly small DOC, low feed rate and high
cutting velocity at MQL condition results low surface roughness with
compromise on burr formation. Minimum tool wear was observed at low
(cutting velocity, feed rate, and DOC) using MQL as cooling method.
Optimum parameters has been established using response optimization to get
output response as minimum. In future, same procedure can be adopted to
replace uncoated tool with coated tool and observe it effect on output response.
