This paper focuses on product data management (PDM) software and its benefits in shop floor documentation. PDM software allows engineers to track and update product information much more easily by providing an integrated environment. It also greatly facilitates the creation and distribution of work instructions. Personnel on the shop floor benefit by having immediate access to the most recent information and more useful and informative instructions.

High direct-voltage ramp tests, according to IEEE Std 95, are used to evaluate the condition of groundwall insulation in rotating machine windings. Evidence of possible defects has been found involving asphalt, polyester and epoxy bonded insulation systems. Some results reflect lack of cure or environmental conditions while other results are indicative of serious groundwall defects which may fail while the machine is in service. Action taken on the basis of the test results is discussed.

Cresylic acid plays an integral part in the application of insulation on magnet wire. It provides the necessary resin solvency, boiling characteristics, and thermal energy to enable efficient and high quality coating of wire-ranging from large rectangular to ultra fine wire. There have been significant changes in the worldwide cresylic acid picture, particularly with regard to raw material sources, production, and isomer distribution. This paper reviews the historical trends and the present situation, describes the evolution of a selected wire enamel solvent product in response to these trends, and looks to the future.

Using quoted price, delivery and production rate as the only criteria for choosing vendors, may well be the correct approach for many industrial purchases. However, following this same doctrine when buying automation equipment, such as coil winding and finishing machines, often leads to making selections that later prove not to be the best choice. Because all the written quote packages appear to address the same key issues, does not mean such machines are generic. They are complex products, with hundreds of details being decided primarily by the builder, not machines produced to an established, third party standard or specification. There will assuredly be significant, but not necessarily evident, differences in the offerings by the competing sales persons. Learning to ask the machine builder the right questions, to correctly identify, understand and properly evaluate the differences is the only practical solution for industry. Business cannot justify the US federal government's approach to make every individual purchase generic via an all-inclusive, comprehensive specification, nor can they afford the results of this concept such as $100 hammers and $400 toilet seats. This paper addresses the fundamental questions and issues that should be explored with potential vendors, to help buyers make better informed decisions.

This paper discusses the influence of material data as well as kinetic parameters on the results of finite element analysis (FEA) simulation of epoxy curing processes. Variations in thermal conductivity significantly influence the calculation of exothermic peaks. Therefore, thermal conductivity values must be determined in the liquid and in the solid state by special experiments. The most influential parameter, however, is the activation energy for the curing reaction. Small variations of 5% already result in calculation errors by a factor of 2. Since measurement errors are in that order, precise determination of the activation energy might be the greatest challenge for simulating the epoxy curing reaction via FEA tools.

Condition-based monitoring of power transformer insulation should center on the prediction of a substantial drop in the dielectric safety margin under the impact of moisture, oil by-products, contaminating particles, paper insulation aging and partial discharge activity. A functional failure model of power transformer insulation and possible effective methods of the insulation condition assessment are discussed based on practical experience.

Through proper application of simulation and modeling within industrial environments, greater impact for energy, waste and production improvements can occur. Modern simulation and modeling systems can help determine impacts of energy and waste reduction concepts on production and vice-versa. Through a 1999 Illinois Department of Commerce and Community Affairs funded project, improvements of over 40% in production, 6% in reduced waste, 3% in employee effectiveness, and a 6% reduction in energy costs were realized through proper use of simulation and modeling in an industrial environment.

For the past decade or more, American manufacturing has been committed to the principle of improving quality. Deming and others have defined philosophies and techniques that lead to improvement. To successfully implement such improvement, critical processes must be carefully monitored through ongoing analysis of process quality control methods. The measurements required to successfully implement statistical quality control (SQC) require more sophisticated instrumentation than simple gauging blocks and other go/no-go testing techniques. Instrumentation needs to give actual measurements, not just limit checks, and the measurements need to be supplied to some statistical calculating engine for SQC. Instrumentation technologies have continued to progress. Data acquisition systems can help to integrate process control with management information systems. Smart sensors, fieldbuses, embedded processors, artificial intelligence and other emerging technologies are becoming available for industrial control applications. There are now great opportunities for manufacturers to have much better understanding and control of their processes. Quality and productivity are dependent upon good instrumentation. The accuracy and timeliness of the instrumentation determine the information used for SQC. This information can be provided to operators in real-time and in a form appropriate for quality control. Significant cost savings are achievable.
