Article history: Received: August 15, 2009. Received in revised form: November 24, 2009. Accepted: November 29, 2009. This paper describes a virtual reality (VR)-assisted robotic surgery simulator for bone surgery training. A trainee surgeon holds the haptic robot stylus and manipulates it three-dimensionally to interact with the virtual bone. The robotic simulator allows the trainee surgeon to...

Continuous production of Al 6061-T6 particulate using modulation-assisted machining (MAM) is demonstrated. Superimposition of a controlled, low-frequency modulation in conventional machining causes chips to form as discrete particles. By adjusting the conditions, equiaxed, platelet and fiber-shaped particles having narrow size distributions can be produced. Large-strain deformation leads to mic...

We present a case of bilateral intractable pneumothorax associated with a modified form of lymphangioleiomyomatosis (LAM), successfully treated with a previously reported surgical procedure, the total pleural covering (TPC) technique, under video-assisted thoracic surgery. The patient was a 28-year-old woman with bilateral pneumothorax secondary to LAM who had undergone thoracoscopic surgery in...

Machining operations are of key importance to the fatigue performance nickel based superalloys due high thermal/mechanical loadings yielded on machined workpiece which can significantly alter surface integrity components. Therefore, understanding influence mechanisms machining induced upon response is vital determine their manufacturing processes and applications. In this respect, paper investi...

In this paper, a thorough review has been presented on the latest research work carried out for the enhancement of machining performance of one of the most commonly used superalloys that is, Inconel 718. The thermal energy has been frequently utilized for improving machinability characteristics of Inconel 718. The review of available literature indicates that plasma, laser, and electric dischar...

The use of high strength materials, like titanium alloys and tool steels, is becoming increasingly common in industry. However, these materials are difficult to machine because they maintain their mechanical properties even at high temperatures. Hence, conventional machining (CM) of these materials is slow and inefficient because only slow cutting speeds can be used. In order to increase produc...

Laser machining/micromachining normally induces in the target material a residual stress distribution, which may favor microcrack propagation leading to reduced fatigue life of the material. This paper investigates the feasibility of introducing the effect of laser shock processing (LSP), that is, imparting a compressive residual stress distribution into the target material, into laser micromac...
