The past two decades have seen the realization of the manufacturing firms towards quality consciousness. The various firms worldwide employed the statistical tools for minimizing the deviations and subsequently the number of rejects of the manufactured parts. In this process, more prominence is laid on prevention of defects rather than detecting and rejecting the defect in the usual traditional...

The fast changing economic conditions such as global competition, declining profit margin, customer demand for high quality product, product variety and reduced lead– time etc. had a major impact on manufacturing industries. To respond to these needs various industrial engineering and quality management strategies such as ISO 9000, Total Quality Management, Kaizen, Just–in–time manufacturing, E...

science and technology world is using computers in different branches as much as possible. virtual reality has variety of application in different engineering fields. simulating softwares increase the accuracy and process speed of analysis. in this research the aim is to use this concept through milling process on cnc machines, so the students can learn objects effectively and eagerly. the appl...

This thesis presents a methodology of improving quality through the use of feedback and lean manufacturing to streamline the process of feedback. As customers' expectations and competition increase, so does pressure to improve quality and reduce manufacturing costs. This thesis examines an approach which improves quality, thereby reducing manufacturing costs. This is accomplished without negati...

To manufacture a product, nowadays there are many methods available in the market to manufacture them and to earn more profits and best production which is the prime focus of any manufacturing industry, it is necessary to select only that type of manufacturing process which leads to more profits, less scraps, and reworks, faster production rate, good quality of production, employee satisfaction...

Resin Transfer Molding (RTM), as a method for the manufacture of advanced ber reinforced composite materials, is attractive because it ooers the possibility of lower manufacturing costs and more complex shapes than traditional methods. A major issue in this new manufacturing process is the elimination of void spaces in the resin ll operation, so that products with high quality are manufactured....

This paper proposes a representation model of the quality state change in an assembly process that can be used in a computer-aided process design system. In order to formalize the state change of the manufacturing quality in the assembly process, the functions, operations, and quality changes in the assembly process are represented as a network model that can simulate discrete events. This pape...

Validation is a tool of quality assurance which provides confirmation of the quality in equipment system, manufacturing processes, software and testing methods. Validation assures the products with predetermined quality characteristics and attributes can be reproduced consistently/reproducibly with in the established limits of the manufacturing process operation at the manufacturing site. Valid...

Most of the inventory control models assume that quality defect never happens, which means production process is perfect. However, in real manufacturing processes, the production process starts its operation in the in-control state; but after a period of time, shifts to the out-of-control state because of occurrence of some disturbances. In this paper, in order to approach the model to real man...
