The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...

during the past decade, polymer nanocomposites have emerged relatively as a new and rapidly developing class of composite materials and attracted considerable investment in research and development worldwide.direct machining of polymers can be an option for personalized products and for manufacturing product samples. to obtain high quality products and reduce machining costs, it is very importa...

With increased application of mechanical micromachining for creating small features with complex geometries on a broad range of materials, the need for understanding the mechanics of machining at the micro-scale has been recognized. During mechanical micromachining of metals, the tool-workpiece interaction occurs entirely within either a single crystal or a few crystals of the workpiece materia...

Residual stresses in a surface layer determine many exploitation characteristics of machined surface. Depending on their kind and the type of applied loading, the influence of residual stresses can be negative or positive. Tensile residual stresses usually exert highly detrimental impact on several functional aspects such as strength, fatigue life, corrosion, wear resistance, etc., whereas comp...

Nowadays, High Speed Machining (HSM) is usually used for production of hardened material parts with complex shapes such as dies and moulds. In such parts, toolpaths generated for bottom machining feature with the conventional parallel plane strategy induced many feed rate reductions especially when boundaries of the feature have a lot of curvatures and are not parallel. Several machining experi...

The machining of complex geometrical shapes with a CNC machine tool requires the determination of cutting conditions namely the depth of cut, the feed rate, the cutter diameter, the number of cutters in use, etc. The number and the diameter of the cutters used for the machining of a given pocket has an important effect on the machining time. Consequently, it is necessary to have an algorithm fo...

It is a very challenging task to develop effective process control methodologies for multi-operational manufacturing processes. Although Statistical Process Control (SPC) has been widely used as the primary method in the control of quality, it mainly serves as a change detection tool rather than a method to identify root causes of process changes. This paper proposes a systematic approach to ov...

In today's industrial world, demand nature is changing where the customers are looking for a high variety of products. In order to meet varying customer demands, the firms should be flexible enough to produce parts in an efficient way. The flexible manufacturing systems have emerged with the progress in manufacturing technology. A flexible manufacturing system (FMS) is a computer-controlled pro...
