Design and Analysis of Carbide Coated Tool on High Strength Alloy Materials Used in Multi Axis Machining

Abstract

Industrial production is characterized by the challenge of machining high strength alloys. Molding and forging dies require high quality, high strength, and low wear materials, so that their mechanical properties are also good. It is important to analyze such alloys before machining in order to reduce tool costs and machining times. The present work focuses on coating high carbide tools used to machine alloys such as H30, SS1803 and titanium at variable speeds, depths, and feeds using the explicit analysis module of ANSYS. To optimize the optimal parameters, the Taguchi method of L9 DOE was used. In this work, a Ø6 mm tool with nickel coating has been used at varying speeds of 1800, 2200, 2500 RPM with a feed rate of 300,400,500mm/min and 0.3,0.4,0.5mm depth of cuts.  It has been observed that maximum damage and interaction forces occur when deformations occur in tools and compared with tools that have not been coated.
