In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration is a frequent problem, which affects the result of the machining, in particular the surface finish. The tool life is also influenced by the vibrations. When the working environment is considered, noise is frequently introduced by dynamic motion between the cutting tool and the workpiece. By pro...

When turning many materials, especially such as high-alloyed steels and a some of non-ferrous metal alloys, long continuous chips are usually formed which clutter the working area machine tools dangerous for workers. One effective reliable methods chip breaking during is vibration cutting, when uniform motion cutter relative to workpeace process superimposed with an additional cutter. The use o...

Polymer concrete or epoxy granite is becoming more popular for beds, bases, and other structures of precision machine tools, owing to its excellent damping characteristics. To realize the same static rigidity as that cast-iron structures, steel-reinforced (SREG) are being used. The vast differences in thermal properties steel (EG) likely cause higher magnitudes error. This work aims investigate...

This paper presents the three dimensional (3D) finite element analysis to predict the workpiece displacement amplitude and tool wear in face turning of AISI 1040 steel under dry machining condition. 3D vibration induced turning models have been developed and validated by comparing with experimental results so as to identify the correlation. Extensive experimentation and investigators carried ou...

Hard coatings such as titanium nitride (TiN) and chromium nitride (CrN) are widely used in cutting and forming tools against wear and corrosion. In the present study, hard coating films were deposited onto AISI 1070 steels by a cathodic arc evaporation plating (CAVP) technique. These samples were subjected to wear in a conventional lathe for investigating the tribological behaviour of coating s...
