Abstract
The quality and performance of a product in service is partly a function of its surface integrity and dimensional accuracies. The cutting tool employed for machining operation plays significant role in the determination of the surface finish of the final product. This study considers the use of the Computer aided modelling and simulation tool (ANSYS 2019) for the determination of the geometrical effects of the cutting tool on the surface roughness of titanium alloy using an indexable double sided round carbide insert milling cutter during milling operation. The cutting tool geometry namely the helix angle (π½π½), number of flutes (n), and cutting edge angle (πΌπΌ) were modelled and simulated iteratively with the
corresponding strain and displacement taken as the response of the designed experiment. In order to validate the numerical analysis, the physical experiments were carried out on test pieces of titanium alloy on a DMC 635 V DMG ECOLINE, Deckel Maho Germany, Siemens 810D, 3- Axis, CNC vertical milling machine and the values of the surface roughness were measured using the Mitutoyo SJ β 201, surface roughness machine. The results obtained produced the most feasible combinations of the cutting tool geometry and cutting parameters that gave the least surface roughness. Hence, the successful completion of this work provides a numerical approach which is validated experimentally. It is envisaged that
the findings in this study will assist manufacturers in predicting and minimizing the magnitude of surface roughness during cutting operations.
