Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...

In this project, we explore a novel framework for formal veriication of a real-time speciications of a machining system. A machining system falls under the broad category of a real-time system. The TTM/RTTL framework is used for speciication and veriication of a machining system. In TTM/RTTL framework, a machining system is modeled as a parallel composition of various modules each representing ...

Nowadays high speed machining (HSM) machine tool combines productivity and part quality. So mould and die maker invested in HSM. Die and mould features are more and more complex shaped. Thus, it is difficult to choose the best machining strategy according to part shape. Geometrical analysis of machining features is not sufficient to make an optimal choice. Some research show that security, tech...

Quality improvements in laser machining have been achieved by a newly developed model-based optimisation strategy. The speci®c aims of such efforts are to assure machining quality right up to boundaries or pre-machined sections, which are inherent in intricate part geometry. Such boundaries frustrate heat-transfer and result in bulk heating of the workpiece. This in turn leads to a degradation ...

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...

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...

Intelligent knowledge based system (IKBS) is developed for optimizing dry CNC turning process using Taguchi method, CNC Machine, EN19 steel as the work piece material, andCutting Insert. Tool wear and spindle loading which are the machining parameters, spindle speed, feed rate, and depth of cut, areoptimized through the intelligent knowledge based system (IKBS). The experimental CNC turning mac...

optimization of machining parameters is very important and the main goal in every machining process. surface finishing prediction is a pre-requirement to establish a center for automatic machining operations. in this research, a neuro-fuzzy approach is used in order to model and predict the surface roughness in dry turning. this approach has both the learning capability of neural network and li...

In die manufacturing industries surface roughness is considered as a vital quality characteristic in order to retain the consumers’ satisfaction. On the other hand, manufacturers want to minimize the machining time which eventually reduces their cost. This research deals with an optimization problem to minimize the machining time (T) for end milling operation on hot die steel (H13), subject to ...

One of the biggest challenges in Aviation industries is milling part features from prismatic blocks to part features with wall and floor thicknesses very similar to sheet metal assemblies. Much research has gone and is still going into machining processes of thin walled components and near net machining. This paper presents an overview in understanding the importance, criticalities and challeng...
