Automatic simplification of highly detailed mesh models has been gaining considerable interest in the research field of reverse engineering and rapid prototyping recent years. However, almost all the present simplification algorithms are only focus on the geometry similarity. The triangle quality and the machinability of the mesh are less considered. We have developed a simplification algorithm...
In the present review, attempts have been made to analyze the metallurgical, mechanical, and corrosion properties of commercial marine alloy duplex stainless steel AISI 2205 with special reference to its weldability, machinability, and surfacing. In the first part, effects of various fusion and solid-state welding processes on joining DSS 2205 with similar and dissimilar metals are addressed. M...
In machining to improve machinability, productivity and to extend tool life coolants and lubricants where used .Increasing industry the use of cutting fluids subsequently increasing this leads in reduce of living conditions nearby future all the governments recommend the manufacturers to reduce the usage of toxicity cutting fluids. Still research for dry machining challenge is exiting for the i...
In this paper a new hardware accelerated method is presented to evaluate the machinability of free-form surfaces. This method works on tessellated models that are commonly used by CAD systems to render three-dimensional shaded images of solid models. Modern Graphics Processing Units (GPUs) can be programmed in hardware to accelerate specialized rendering techniques. In this research, we have de...
Hard turning of martensitic stainless steel is gaining importance in all manufacturing sectors like automobile and aerospace industries. Machinability of materials depends on surface roughness, tool wear, cutting forces, specific cutting pressure and work material hardness. In this research hard martensitic stainless steel AISI 440 C and SCM 440 alloy steel was used as work materials. CBN and P...
In recent year’s aluminum and aluminum alloys are widely used in automotive industries. These are light weight (density of about 2.7g/cc),having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. High machinability and workability of aluminum alloys are prone to porosity due to gases dissolved during melting processes. However, in the engi...
& 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...
Most of the materials used in the industry of aero-engine components generally consist of titanium alloys. Advanced materials, because of their excellent combination of high specific strength, light weight and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provides a serious challenge for cutting tool material during the machining process. The reduction in ...
