In situ strain measurement in the chip formation zone during orthogonal cutting
The in situ strain measurements during orthogonal cutting were performed to get information about the local stress state in the chip formation zone. These results will be used to verify and extend existing chip formation models. Until now the existing chip formation models, e.g. [1-3] are relying on a number of restricting preconditions, because the strain and stress fields in the chip formatio...
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 کاملInfluence of Rake Angle and Hardness Ratio on the Formation of Discontinuous Chip during Orthogonal Metal Cutting
In the present investigation, numerical models that accurately predict the chip formation and stress profiles in the work-piece during orthogonal metal cutting were developed using the explicit finite-element method (FEM). More specifically, a damage material model was utilized to capture the work-piece chip formation and simultaneous breakage of the chip into multiple fragments. In the simulat...
متن کاملشبیهسازی 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...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
