Original scientific paper In this paper, the results of investigations of the temperature field distribution and tool wearing during C60 steel turning are presented. Abrasive wear resistance tests were carried out for cutters made of low-alloy high-speed steel. Steel samples were heat treated, and then were subjected to ion nitriding, TiN coating, or to complex treatment. The influence of cutti...

This work evaluates the possibility of identifying mechanical parameters, especially upper and lower yield points, by the analytical processing of specific elements of the topography of surfaces generated with abrasive waterjet technology. We developed a new system of equations, which are connected with each other in such a way that the result of a calculation is a comprehensive mathematical-ph...

In this paper, an attempt has been made to characterize the surface texture generated, during Magnetic Field Assisted Abrasive Finishing (MFAAF) of SS316L material. The changes in surface texture generated are studied by using surface roughness profiler, Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). The deep cutting marks left by grinding process have been removed and re...

As abrasive water jet (AWJ) starts to be used in industry, especially in aerospace and automotive industries extensively, getting high quality surface has become a major requirement. Being a promising non-traditional cutting process, AWJ is holding several deficiencies, which limits its extensive applications dramatically. One of the deficiencies is striation marks presented on AWJ cutting surf...

One of the major tasks in a Molecular Dynamics (MD) simulation is the selection of adequate potential functions, and if the potentials don’t model the behaviour of the atoms correctly, the results produced from the simulation would be useless. Three popular potentials namely; EmbeddedAtom Potential (EAM), Morse and the Lennand-Jones, were employed to model copper workpiece and diamond tool in n...

Water jet and Abrasive Water Jet (WJ/AWJ) are manufacturing technologies suitable for particular operations (cutting, milling, turning, surface treatment, etc.) on different types of materials. The use of water (or water mixed to abrasive in AWJ technology) allows working both soft and hard materials without damaging the interested area of the workpiece. In previous studies the authors have jus...

Experimental study on slicing of sapphire with fixed abrasive diamond wire saw was conducted in this paper. The process parameters were optimized through orthogonal experiment of three factors and four levels. The effects of wire speed, feed speed and tension pressure on the surface roughness were analyzed. Surface roughness in cutting direction and feed direction were both detected. The result...

In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...

Many manufacturing defects could be seen in cylindrical turning. Some of these defects are: elastic deformation of work-piece, nonlinear backlash of cutting set – machine – workpiece, unknown geometry of untreated part, thermal deformations, vibration of set and machine. Deflection of workpiece under cutting forces will cause different levels of processing of workpiece 1 . Nonlinear backlash of...
