Reliability: The reliability of the machine is a very important if the machine has to find the huge market in the business. The ERM programs of several U.S. and Japanese manufacturers are outlined in the following paragraphs. Lacking standard measures of ERM and using reward systems that typically do not encourage operators or supervisors to record or try to maximize equipment performance, industry can give suppliers very little information about its equipment beyond installation. A complementary focus is needed on using technology. Source: Intel Corporation, 1989. able body of knowledge, much like that available for engines in the aircraft industry today. SUBSTANTIAL CAPITAL investments, in the form of facilities and equipment, are required for manufacturing almost all goods of economic significance. This vision for ERM is rooted in the evolution of product and process design and intelligent. This correct diagnosis avoided both an unscheduled outage for repair and a probable forced outage later had the problem gone undetected during the scheduled outage. An understanding of enterprise optimization is needed to guide the application of technical work in the plant. Over the next several product generations, the cost of such facilities is expected to reach between $500 million and $750 million (Figure 3-2 ). effectively promote ERM, a clear and strong initiative is needed to identify what needs to be changed, what the objective should be, and how to make the change, in order to have an immediate and significant impact with lasting effects. Needed in equipment design is a design-for-reliability approach that takes into account all life-cycle costs (acquisition, installation, operation, maintenance, repair, and salvage). In fact, to the extent that they lead management to treat maintenance as an indirect cost that increases factory overhead, these systems may be putting the U.S. asset base at risk. design trade-off between reliability and maintainability. Jump up to the previous page or down to the next one. throughout the life of the product with low overall life-cycle costs. Reliability is the probability that a product will continue to work normally over a specified interval of time, under specified conditions. Firms that do value ERM, typically driven by powerful cus-. Arguments that blame insufficient capacity on old machines that cannot be replaced because of high cost are suspect because the most cost-effective increase in U.S. manufacturing capacity may well be achievable through improved maintenance practices for existing equipment. Book: Machine Design by Dr. P. C. Sharma and D. K. Aggarwal. Economy of repairs and maintenance: While designing the machine elements and machine the designing should be such that least amount of repairs and maintenance will be required for the machine. This volume presents a concise and well-organized analysis of new research directions to achieve these goals. Do you want to take a quick tour of the OpenBook's features? ERM does not begin on the manufacturing. Kaplan, R. S. 1989. The cumulative effect of these practices is reflected in the product—mass-produced automobile body parts that are. It is seldom possible to predict how a system will fail when something somewhere in the plant breaks down. Industrywide collections of such information will facilitate sharing of technical data—both ERM statistics and qualitative information about the relative effectiveness of different techniques—and help pinpoint areas where improvement is essential to global competitiveness. 2. Factor of safety (FoS), also known as safety factor (SF), is a term describing the structural capacity of a system beyond the expected loads or actual loads. While total abandonment of tradition, or complete cultural change, is neither possible nor desirable, U.S. manufacturers may need to import, adapt, and fine-tune techniques from other countries such as Japan. Source: VLSI Research Inc. Key elements of the design/development phase include training and development to enable suppliers to perform highly specialized equipment analyses, such as failure modes and effects criticality analysis (FMECA), fault tree analysis, design for testability, design for fault tolerance/isolation/tracking, and design for remote diagnosis. As a result, it is difficult to make comparisons, share results and good practices among cooperating operations, and measure ERM performance trends in any one factory in a universally credible way. Barriers to this vision of ERM are manifold. divided by the factor of safety. 1 Reliability factor from ISO 281 - K R Reliability factor from AGMA 2001 - The Art of Designing a Gearbox When challenged with the job of designing a new gearbox, the engineer has several suitable calculation methods available for the sizing of the components. An equipment life-cycle training course was developed to train new suppliers, manufacturing engineers, and procurement teams.
