Title

Computational Modeling of Residual Stresses in Simultaneous Turning Process

Abstract

Residual stresses play a vital role in determining the quality of the turned components. 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. In this paper numerical investigation was performed to determine the effect of chamfer angle and chamfer width for various feeds on the surface residual stresses. The numerical simulation was done using commercially available software ABAQUS 6.14. The work and tool material are AISI 4340 steel and carbide. CPE4RT four node plane strain element was used for the analysis. A Johnson-Cook damage criterion was employed for the chip separation. The friction between the chip and the cutting tool was based on penalty contact approach. The coefficient of friction was taken as 0.3. With the increase in chamfer angle and chamfer width, the surface residual stresses increases. This is attributed to the increase in cutting forces and plastic 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.
