Product design evaluation is essential for all manufacturing industries to explore the soundness and effectiveness of the product design. This paper presents a mathematical model for evaluating and analyzing the product design alternatives using graph theory and matrix approach. In this paper, various contributing factors are identified and their relative importance has been considered. A digraph...
In this paper, we propose a prototype of a (collaborative) teleassistance system for mechanical repairs based on Augmented Reality (AR). This technology is generally used to implement specific assistance applications for users, which consist of providing all the information, known as augmentations, required to perform a task. For teletransmission applications, operators are equipped with a wearable...
Virtual reality (VR), even if it does not represent any more a novel technology, is one of the most powerful tool to help designers during the development of new projects. This is proved by very numerous research activities related to this field. In this research, we have studied a new way to approach the development of a product. We present the ongoing development of a system, called VirDe, acronym...
This paper describes the development of regression based mathematical models for the prediction of springback in air bending process of interstitial free (IF) steel sheet. Punch travel (d), strain hardening exponent (n), punch radius (rp), punch velocity (vp) and width of the sheet (w) have been considered as input parameters and springback as output parameter to develop the model. Based on experimental...
This study demonstrates optimization of CO2 casting process parameters by using Taguchi’s design of experiments method. The CO2 casting process involves a large number of parameters affecting the various quality features of the final product. The process parameters considered in this research work are weight of CO2 gas, mould hardness number, sand particle size, percentage of sodium silicate, sand...
