Surface Roughness of Stainless Steel by Micro-Milling for Biomedical Applications

Biomedical industry is one of the fastest growing industries nowadays. A lot of improvement and development has been done in order to maintain the usage for biomedical industry. Stainless steel is one of the material that usually been used in this industry but still need to be improved so that every weaknesses can be taken out. Stainless steel also can be processed by milling operation. By milling operation, it will affect the surface roughness of the material.
It is important for a material especially for material in biomedical industry to have the optimum value of surface roughness so that it will meet the requirement that is needed by the body. To obtain the optimum surface roughness, we need to find the optimum feed rate, spindle feed and also depth of cut. From the optimum value of all those three variables, and the value that is obtained can be used as the reference for future works.
