Presently the prime task of manufacturing engineers is to make products within a short span by maintaining the best quality at minimum cost. Recent market trends confirm the continuation of New Product Development (NPD) as a change agent for many more years to come with a focus on high product variety and shorter product life cycles. The effective introduction of new products is critical to the performance of manufacturing industries in more industrial sectors. It is a measure of an industry's strength in innovation and competitiveness in NPD. Manufacturing industries are forced to accept that the focus on NPD is on increasing product variety and shorter product life cycle. For many manufacturing industries, mass customization with "voice of customer", agility and leanness are some of the vital prerequisites to survive in the current global competitive environment. NPD is no longer an isolated process; it requires close integration between all active members within the supply chain such as customers, suppliers, manufacturers, etc. and must be viewed as an integrated business process. The proper use of advanced IT has enhanced NPD in manufacturing enterprises. It facilitates shorter product lead-times and increases responsiveness to changes in the market along with improved product quality, as well as maintaining low product cost.
In global competitive atmosphere, foundry industries are needed to perform efficiently with minimum percentage of rejections there by reducing cost of manufacturing. Foundries are using state of art processes with the involvement of experienced and knowledgeable people but the experience and knowledge needs to be transformed for the growth of the industries. Some foundries are working in a trial and error mode and get their work done. Many foundries have very less control on the rejections since they are in critical need of meeting production targets and they ignore the rejections and recover the castings. They need to have an efficient quality control aspiring for defects free castings with minimum production cost. Strategic decision makers need extensive models to guide them for efficient decision making that increases their profitability of the entire chain. The noval idea of this research is to investigate the various defects of cast iron foundry and suggest remedies for the defects in a day to day activity and propose a supply chain model to present the necessity of quality in a medium scale industry of cast iron foundry under different delay conditions, rejection rates and also various other factors. The results of the proposed model have been discussed and confirmed based on the original results of an industry. This research is also inspects the relationship between supply chain processes and quality as a key role in supply chain management.
As it stands now, rubber has been the main material used in the making of pneumatic vehicle tyres. Speed of the vehicle depends on many factors like steering geometry, inflation pressure, vehicle load, road temperature and environmental conditions. The main aim of this research is to develop a finite element approach and computationally evaluate the performance of a steady-state rolling tyre by changing the tyre tread patterns. The tyre normally composed of rubber and body-ply was investigated with regards to the effect of the inflation pressure. Tyre modeling using six different types of patterns was completed by using Creo parametric 3D modeling software and then the tyre was discretized into small elements through ANSYS R16.2. The rim area of the tyre was fixed and pressure was applied to the inside surface of the rim. Finite element analysis was completed by using ANSYS R16.2 and equivalent stress, contact stress and contact pressure were found out to identify the best tyre pattern. From the final results it was observed that, Pattern-I had good agreement of results as compared to other type of patterns which showed medium frictional stress and contact pressure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
