Abstract

Residual stresses carry a vital role in determining the quality of the turned workpieces. Numerical modelling of residual stresses provides a deep insight of the process mechanism and increases the productivity by conserving time, material and manpower. In simultaneous turning process, two tools are engaged simultaneously to perform the turning process. This research work focuses on numerical investigation to estimate the impact of chamfer angle and width for various feed on surface residual stresses. The numerical simulation was done by commercially available finite element code. The work and tool material are AISI 4340 steel and carbide. CPE4RT four node plane strain element was used for the analysis. A widely used damage criterion was employed for the chip removal. The coefficient of friction in between the sliding surfaces was based on penalty approach. The friction coefficient was taken as 0.3. With the increase in chamfer angle and chamfer width, the surface residual stresses increase. This is caused by the rise in cutting forces and inelastic strain. At constant chamfer angle, with increase in cutting speed the cutting forces remain constant for both the cutting tools. The same trend was also observed for the chamfer width. On the whole, the usage of chamfered cutting tools proved to be beneficial in imparting higher compressive residual stresses in the simultaneous turning process.

Key Words

Chamfer angle, Chamfer width, Residual stress, simultaneous turning, cutting speed, feed.
