Relationship between machining parameters and surface roughness of brass using lathe machine.

摘要

Surface roughness is a consequence of all machining operations and has been the subject of investigative research for the better part of the last century because the product produce good surface finish is very valuable. But, not all the product needs a good surface finish. If the product not demands a good surface finish, the time of machining can be reduce to minimize the cost. This is about the effect of machining parameters on surface roughness using lathe machine. The focus of this project is to study the effect of Cutting speed, feed rate, and depth of cuts on brass`s surface roughness. The experiment was design using Design of experiment (DOE) method and from which number of experiment was constructed. The result show that feed rate is the most effected parameter on surface roughness when machining process then followed by depth of cut and cutting speed. All the parameters are proportional with brass`s surface roughness.
