Effect of Variable Pitch on Cutting Temperature, Cutting Forces and Surface Roughness Using Nitico30 Cutting Tool when End Milling of Stainless Steel 316L

Abstract

In this paper, a series of milling tests were carried out in order to identify the effects of variable pitch on cutting temperature, cutting force and surface roughness while end milling the stainless steel 316L using Nitico30 and conventional cutting tools. Slot-milling operations were conducted. The value of feed rate were choose between the range recommended by the manufactured for the both conventional and Nitico30 cutting tool. The effect of variable pitch on cutting temperature, cutting forces and surface roughness were discussed. Results showed that the cutting temperature increase with the increase of feed rate for both cutting tool. Further increasing the speed of feed rate, the cutting forces also gradually increase for both cutting tool. However, the comparison between both cutting tools, it was found that the cutting temperature, cutting force and surface roughness improve about 47.8%, 37.5% and 17.6% respectively for Nitico30 cutting tool.
