The use of ionized gaseous medium (IGM) to prepare a hard alloy material surface by grinding and its effect on the coating quality was investigated. During grinding, IGM was fed to the cutting area by different methods namely: clockwise (longitudinal), anticlockwise (opposed) and transverse (Cross) feeding, respectively. Thereafter, the samples were coated with a titanium nitride on a modern va...

Cutting wounds and bruises in the area of neck are very specific. The overall rehabilitation of these conditions is difficult and often needs to be combined with special and customised orofacial prostheses. This case-study reports special multidisciplinary treatment. The surgical diagnosis was: a cutting wound on a neck caused by a chain saw and disruption of oropharynx. Due to contusion of the...

The present paper is on the physical and mechanical characterization of machined chips commercially available highly conductive metallic materials, namely aluminium copper under different machining environments. More specifically, geometry hardness as well removal effect surfaces are investigated in a quantitative fashion function fluid cutting parameter. carried out by using horizontal shaper ...

The effect of different cutting fluids on surface roughness brass alloy workpiece during turning operation was carried out in this research. This performed with speed, while other parameters had been regarded as constants(feeding rate , and depth cut). Surface machined parts that will be tested by electronic tester .The results show the standard coolant gives best values for fixed speed ,follow...

& Minimum Quantity Lubrication (MQL) machining involves the application of a minute amount of an oil-based lubricant to the machining process in an attempt to replace the conventional flood coolant system. Understanding the correlations between fluid properties and MQL performance can help in selecting lubricants from a variety of choices without going through extensive machining tests. This st...

Water-soluble metal working fluids are used for processing of aluminum alloy materials. This short paper describes properties of new additives for water-soluble cutting fluids for aluminum alloy materials. Some alkyldiphosphonic acids were prepared with known method. Amine salts of these phosphonic acids showed anti-corrosion property for aluminum alloy materials. However, they have no hard wat...

Abstract The abundant use of cutting fluids in surface grinding process and the corresponding costs energy consumption have been a major sustainability concern. This paper identified optimum depth cut for under controlled parameters using compressed air cooling technique dry cutting. morphology subsurface defects workpiece material (AISI 304 stainless steel) were measured compared. It was obser...
