Mechanics of high speed cutting with curvilinear edge tools
High speed cutting is advantageous due to the reduced forces and power, increased energy savings, and overall improved productivity for discrete-part metal manufacturing. However, tool edge geometry and combined cutting conditions highly affects the performance of high speed cutting. In this study, mechanics of cutting with curvilinear (round and oval-like) edge preparation tools in the presenc...
متن کاملComparison of Cutting Ceramics with Hard Metal Cutting Tools
Cutting ceramic tools are used especially at high cutting speeds in the machining process. The highly brittle type of structure and the tendency for cleavage (crack formation) are the infavorable properties of these materials, which keep their hardness at high temperatures. The hard metals are produced by sintering of the carbides such as whisker WC, TiC and TaC with the presence of Co as a bin...
متن کاملChip 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...
متن کاملFinite Element Modelling and Simulation of Chip Breaking with Grooved Tool
A finite element model is presented to simulate chip breaking when orthogonal turning medium carbon steel with a grooved cutting tool is used. The chip formation, chip breaking, cutting force, stress, strain and temperature are simulated by the thermo-elastic-plastic finite element method, using commercial finite element software. The cutting process is simulated from the initial to the steady-...
متن کاملElliptical Vibration Cutting of Steel with Diamond Tools
Diamond turning of steel alloys is impractical due to catastrophic tool wear caused by a combination of chemical and abrasive wear. In the literature, several modifications of the cutting process have been proposed, e.g. cutting in an inert gas atmosphere, cryogenic cutting and vibration assisted cutting, e.g. elliptical vibration cutting (EVC) [1-5]. In this work, the EVC method was investigat...
