Analysis and Modeling of Single Point Cutting Tool with help of ANSYS for Optimization of Vibration Parameter

Machining is process where material is removed from the workpiece and is often accompanied by Self-excited vibration generated by the cutting process or by friction. These vibrations are undesired and have to minimised. Here, a single point cutting tool (20x20x40) made of molybdenum High Speed steel (UNST11302) is used for turning operation. It experiences forces due rotation of spindle, feed rate and depth of cut (2000 N, 1100 N, 1000 N) which produces vibration in tool as stated above. This is responsible for high wear and tear of tool. The tool is modeled in ANSYS Workbench. Modal analysis is done to determine the natural frequency of the work piece. With the range of frequency obtained from modal analysis, harmonic analysis is done to study the vibrational effect. To minimise this, optimization is done to find dimension of tool for which it experiences minimum vibration and minimum stresses so that it may work for longer period of time or its life may be enhanced. The tool having cross sectional dimension of (19.8x 18.7) and (21.8 x 20.45) and have minimum vibrational effect and minimum vibrational effect and equivalent stress both respectively.
