Cutting Aluminium Coils with High Length VariabilitiesChristoph
A case study of a cutting stock problem in an aluminium mill is presented. Orders have release dates, due dates, a total length and may be delivered in any number of coils within rather large length intervals. A variety of diierent cutting machines is available, hierarchical cuts may be necessary to produce small widths. The mill is capable of producing custom{made coils within certain bounds b...
متن کاملAnalysis of Orthogonal Metal Cutting Processes
The orthogonal metal cutting process for a controlled contact tool is simulated using a limit analysis theorem. The basic principles are stated in the form of a primal optimization problem with an objective function subjected to constraints of the equilibrium equation, its static boundary conditions and a constitutive inequality. An Eulerian reference co-ordinate is used to describe the steady ...
متن کاملStudy of Cutting Temperature in Orthogonal Milling
Finite Element Method (FEM) based techniques are available to simulate metal cutting processes and offer several advantages including prediction of tool forces, distribution of stresses, and temperatures, estimation of tool wear, and residual stresses on machined surfaces, optimization of cutting tool geometry, and cutting conditions. However, work material flow stress and friction characterist...
متن کاملInfluence of Water Cooling on Orthogonal Cutting Process of Ti-6Al-4V Using Smooth-Particle Hydrodynamics Method
Temperature control during the cutting process with different parameters such as cutting velocity and applying water cooling is essential to decrease the cutting force, increase the life of the cutting tool and decrease the machined surface temperature of work-piece. In this research, the temperature of machined surface and the chip-tool interface in orthogonal cutting process of Ti-6Al-4V were...
متن کاملnumerical simulation of orthogonal cutting process and determination of built up layer thickness
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...
