Experimental Investigation for Tool Life by Optimizing Machining and Geometric Parameters of CNC End Mill Tool
Keywords:CNC end milling, Taguchi method, ANOVA, Tool life
CNC end milling is a unique adaption of the conventional milling process which uses an end mill tool for the achining process. During the End milling process, the material is removed by the end mill cutter. The effects of machining parameters of end milling process like spindle speed, depth of cut and feed rate and geometric parameter rake angle
of a 14 mm diameter HSS end mill tool have been investigated on a AISI 1025 MS plate work material for pocket milling operation to reveal their impact on tool life using Taguchi Methodology. Experimental plan is performed by a Standard Orthogonal Array three times. The results of analysis of variance (ANOVA) indicate that the proposed mathematical odel can be adequately describing the performance within the limit of factors being studied. The optimal set of process parameters has also been predicted to maximize the tool life.
