Comparison 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 کاملAssessment of Machinability of Metal Cutting
The assessments of machinability of metal cutting are called "indices" and are derived by comparative research. These indices are the relations of two identical parameters, such as is the allowable cutting speed. The assessments were obtained at a constant tool life of 60 min, at the appropriate tool life minimum costs and the efficient reporting of specific restrictions for finishing and rough...
متن کاملMathematical Modeling of Metal Cutting Process
In the practice of metal treatment by cutting it is frequently necessary to deal with selfexcited oscillations of the cutting tool, treated detail and units of the machine tool. In this paper are presented differential equations with the delay of self-excited oscillations. The linear analysis is performed by the method of D-expansion. There is chosen an area of asymptotically stability and area...
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 کاملWaste Prevention: from Concept to Practice
According to the revised European Union (EU) Directive on Waste (2008/98/EC), widely known as Waste Framework Directive (WFD), waste prevention embraces all the measures taken before a substance, material or product has become waste, that reduce the quantity of waste, the adverse impacts of the generated waste on environmental and human health, and the content of harmful substances in materials...
