چکیده

The paper describes micro structural observation (LM and SEM), which has been made on quick-stop sectioned samples of the chip formation, either on metals (high-speed steels) and Ti3SiC2 ceramic. All milling tests were carried out using a “quick-stop” method developed by the authors. For micro structural analysis samples were prepared by standard metallographic technique and examined with a light microscope and scanning electron microscope. Compared to conventional cutting of metals, a significant difference in chip formation was noticed when Ti3SiC2 ceramic was machined. Although during machined powder-like chips were obtained and it was observed that breaking of chip appeared without previous plastic deformation.

Chip Formation Process using Finite Element Simulation “Influence of Cutting Speed Variation”

The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...

A SVM model to predict the hot deformation flow curves of AZ91 magnesium alloy

Abstract In this work, a support vector machine (SVM) model was developed to predict the hot deformation flow curves of AZ91 magnesium alloy. The experimental stress-strain curves, obtained from hot compression testing at different deformation conditions, were sampled. Consequently, a data base with the input variables of the deformation temperature, strain rate and strain and the output variab...

شبیه‌سازی المان محدود فرایند برش متعامد و تعیین ضخامت لایه چسبنده به ابزار در ناحیه دوم برش

The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

Machinability evaluation of Titanium alloy in Laser Assisted Turning

The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...
