Article history: Received: 27.6.2013. Received in revised form: 14.11.2013. Accepted: 19.11.2013. Aluminum based Metal Matrix Composites (AlMMC) have been found in different industrial applications due to their excellent properties compared to conventional materials. Machining of these composites is difficult due to their hard particle reinforcements. The wider usage of these composites is limi...

Abstract The machinability of Ti-6Al-4V alloy has been a constant challenge in the industry, although material is widely used aerospace and medical industries due to its mechanical properties, particularly strength-to-weight ratio. current research presents hybrid laser- ultrasonic-assisted machining (LUAM) technique improve turning process. This compared with (UAM), laser-assisted (LAM), conve...

A three-dimensional cutting simulation prediction model based on DEFORM-3D finite element software was developed and experimentally validated, with a maximum error of 21.1% between the experimental results. The effects difference in mechanism conventional machining (CM) laser-assisted (LAM) TC6 titanium alloy tool wear surface roughness were investigated terms force temperature. depth laser-hea...

In the deformation and cutting process of semiconductors and ceramics, especially brittle materials such as silicon carbide (SiC), the presence of high pressure phase transformation (HPPT) is of great importance for accomplishing ductile regime machining (Patten, 2007). To augment the ductile regime machining of these nominally brittle materials, the high pressure phase can be preferentially he...

Inconel 718, a high-temperature alloy, is a promising material for high-performance aerospace gas turbine engines components. However, the machining of the alloy is difficult owing to immense shear strength, rapid work hardening rate during turning, and less thermal conductivity. Hence, like ceramics and composites, the machining of this alloy is considered as difficult-to-turn materials. Laser...

Laser assisted machining is an alternative to conventional machining of hard and/or difficult-to-process materials which involves pre-heating of a focused area with a laser beam over the surface of the workpiece to cause localized thermal softening along the path of the cutting action. The main advantage that laser assisted machining has over conventional machining is the increased material rem...

Abstract High flexibility of the micro-milling process compared to nontraditional methods has led its growing application in manufacturing complex micro-parts with tight tolerances and high accuracies. However, difficulties such as tool deflection, size effect, wear limit micro-milling. In this regard, role laser-assisted machining (LAM) is highlighted prevent mentioned issues through reduction...
