This paper first enlists the generic problems of alloy wheel machining and subsequently details on the process improvement of the identified critical-to-quality machining characteristic of A356 aluminum alloy wheel machining process. The causal factors are traced using the Ishikawa diagram and prioritization of corrective actions is done through process failure modes and effects analysis. Proce...

This paper deals with the design of aluminum alloy wheel for automobile application which is carried out paying special reference to optimization of the mass of the wheel. The Finite Element analysis it shows that the optimized mass of the wheel rim could be reduced to around 50% as compared to the existing solid disc type Al alloy wheel. The FE analysis shows that the stress generated in the o...

The paper highlights the importance of employee/customer involvement in six-sigma implementation. For six-sigma a company not only needs a certain pool of resources, it also needs organizational competencies in terms of a motivated workforce and involved customers. Employee involvement leads to low worker role ambiguity, removal of cultural bottlenecks, worker empowerment, and worker motivation...

A great number of wheel tests are required in designing and manufacturing of wheels to meet satisfactory requirements. The impact performance of a wheel is the major concern. Numerical implementation of impact test is essential to shorten the design time, improve the mechanical performance and lower development cost. Project includes the “Topology Optimization of Cast Aluminium Alloy wheel” usi...

India is one of the largest automotive industries in the world and one of the fastest growing globally. Now all automakers are concentrating on India for the promising growth in the sector. So competition in this industry is very high. Hence, there is a need to focus more on product development. The development of the product needs to be started from conceptual design with low cost, high perfor...

A grinding force model is developed to predict the forces during the face grinding of cast iron and aluminum alloy 319. Design of experiments methods are used to create a response surface of four process parameters: feed rate, inclination angle of the grinding wheel profile, offset angle between the grinding wheel and the workpiece, and the peripheral speed of the wheel. For each material, thre...

Background Individuals who experience childhood trauma are vulnerable to various psychological and behavioral problems throughout their lifetime. This study aimed to investigate whether individuals with childhood trauma show altered frontal lobe activity during response inhibition tasks. Methods In total, 157 healthy individuals were recruited and instructed to perform a Go/Nogo task during e...

Medicine is an applied science, interpreting evidence and applying it to real life by using clinical reasoning skills and experience. COPT (clinically oriented physiology teaching) was incorporated in physiology instruction aiming to relate the study of physiology to real-life problems, to generate enthusiasm and motivation for learning, and to demonstrate the vocational relevance of physiology...

Six Sigma and Design for Six Sigma (DFSS) offer a new approach to Total Quality Management with a more integrated approach, standardized training and certification, and financial accountability for i nvestment in improvements. A core principle of DFSS is the Transfer Function (y=f(x)), whereby customer requirements are transferred into Critical-to-Quality requirements (CTQ). DFSS uses the House...

In this study, the grindability of cast magnetic alloys (Fe-Pt-Nb magnetic alloy and magnetic stainless steel) was evaluated and compared with that of conventional dental casting alloys (Ag-Pd-Au alloy, Type 4 gold alloy, and cobalt-chromium alloy). Grindability was evaluated in terms of grinding rate (i.e., volume of metal removed per minute) and grinding ratio (i.e., volume ratio of metal rem...
