Abstract
The project aims at effect of cutting forces on the drill & end mill cutter tools in modern manufacturing. For High-speed machining operation, accuracy of tool tip places a vital role in mass manufacturing. In order to get high precision, high-efficiency automated production the tool life should be longer enough to withstand various stresses acting on it. The main aim is to develop the combination of optimum cutting parameters by using taguchi method. In this project design of experiment has been employed with L9 (3^3) Orthogonal Array for three parameters namely Speed, Feed and Depth of cut. For each of these parameters three different levels have been identified and used to perform the cutting parameters for minimizing the stresses acting on various tool in SINEWAVE© VMM-A-200 CNC Milling Machine. The material selected for machining was Aluminium plate with drill & end drill cutter tools. Cutting forces are experimentally determined at a tip of cutting tools during machining by milling tool dynamometer. From the obtained cutting forces are applied on tip of cutting tools and results are evaluated using ANSYS software such as various stresses, strain and total deformation are found. Cutting Tools are modelled in CREO software and the model is then imported in ANSYS software for analysis. Also, from stress analysis of milling tool it is evident thrust force play a vital role in machining, whenever the stress is minimum then the tool life become maximum.
