Abstract. In this paper we present a study on numerical simulation of turning
process using finite element analysis program AdvantEdge TM for AISI 1060
carbon steel material. The main objective is to determine the influence of different
cutting parameters (depth of cut, feed rate and cutting speed) on cutting force, von
Mises stress and temperature in the longitudinal turning process. The predict of
cutting forces by numerical simulation is important for the optimization of the
process. The simulations were conducted without coolant.
Key words: turning, numerical simulation, cutting forces, temperature.
1. Introduction
The turning process is probably the most important process of all cutting
processes. It is therefore very important to analyze the process for to
optimization it.
Cutting force has a value and direction of action that depend on the quality
of processed material, on the cutting regime elements, geometric parameters of
cutting tools, cooling-lubricating liquids [4].
The resultant cutting force is defined by the relation:
(1) R = ( F + F + F ) ≈(1.1…1.18)·Fx,
where:
Fz=(0.2…0.3)·Fx,
Fy=(0.25…0.4)·Fx.
