Micro electro discharge milling (MED milling) is a spark erosion method capable of micromachining prismatic and complex shapes using simple non-profiled tool. Tool wear poses major hurdle in the development of MED milling. This paper discusses the types of tool wear in MED milling and analyses...
Cellulosic biofuels are an alternative to petroleum-based transportation fuels. Ultrasonic vibration-assisted (UV-A) pelleting can increase density of cellulosic feedstocks, reduce transportation and storage costs, and increase sugar yield. However, energy consumption in UV-A pelleting has not...
This paper proposed a post-classifying fuzzy-neural and data-fusion rule to improve the performance of job scheduling in a wafer fabrication factory (wafer fab). The proposed rule is a hybrid (fusion) of two well-known fluctuation smoothing rules – FSMCT and FSVCT. Several ways of data fusion...
The purpose of this research work is to design an optimum fixture layout in order to reduce the maximum elastic deformation of the workpiece caused by the clamping and machining forces acting on the workpiece while machining. First a genetic algorithm (GA) based optimisation procedure to solve...
This work investigates the cutting performance of chamfered PCBN tools in hard turning of GCr15 bearing steel. Experimental study was performed on a NC lathe. Cutting forces were measured by using a dynamometer. Cutting temperature was measured by using an infrared thermal imager. The variation...
An increasing use of sculptured surfaces by blending non-uniform rational B-splines (NURBS) has been observed in the consumer product design. For machining of sculptured objects, there are numerous toolpath generation techniques available in literature. However, several researchers’ have noted...
