ANALYSIS OF CUTTING FORCES OF FLITCHED TOOL HOLDER USING ANSYS

Abstract

• Introducing a novel Lathe single point tool holder named Flitched tool holder.This tool holder is manufactured by 3D printing method. It is nylon made and sandwiched between two mild steel plates. Investigating this novel tool holder, this research work focus on the cutting forces generated on the Flitched tool holder while machining Polytetrafluoroethylene (PTFE- Teflon). In experimental work, the TNMG Insert is used. Modelling of the Flitched tool holder is done by Catia v5. The model meshing is done with the help of ANSYS. The ANSYS analyzed model by FEA at different forces and measures the stresses and deformation generated in the Flitched tool holder. Forces were calculated by Analytically and Experimentally at input factors like F, DoC., CS Experimental results are analyzed, and optimum parameters are achieved by Taguchi and ANOVA. For this, L27 Orthogonal array of Taguchi method is used. In the Finite element analysis of the Flitched tool holder, Also, the maximum deformation that takes place at and under the tip of the Insert of the Flitched tool holder, which blunts the tool, is the cause of failure. It is investigated that, Flitched tool holder for TNMG Insert is sustained up to the max. Force 60N which, is generally induced while machining PTFE –Teflon with other steel tool. Hence concluded that, Polymer Flitched tool holder has the capability of machining PTFE –Teflon effectively.
