Escape from the unnecessary : some guidelines for production management

Abstract: This paper emphasizes the importance to a manufacturing company of decreasing the product structures, both in width and depth, thereby shortening the throughput times, standardizing and reducing complexity, and identifying bottlenecks in order to increase efficiency and profitability. Having once been a production control and plant manager at Ericsson and Benzlers, the author has drawn upon his experience in researching this paper. Other influences include knowledge of well-known trends in production management, e.g. WorldClass Manufacturing, Lean Production, Time-Based Management, OPT, etc. The paper also stresses that it is difficult to present real new ideas concerning production management, but nevertheless discussions and publications of ideas and incentives to achieve an efficient production of products and services must continue.

Lead-free solder implementation for automotive electronics

Abstract: Lead-free solders for electronics have been actively pursued since the early 1990's here and abroad for environmental, legislative, and competitive reasons. The National Center for Manufacturing Sciences (NCMS-US), the International Tin Research Institute (ITRI-UK), Swedish Institute of Production Engineering Research (IVF-Sweden), Japan Institute of Electronics Packaging (JIEP-Japan), Improved Design Life and Environmentally Aware Manufacture of Electronics Assemblies by Lead-free Soldering (IDEALS-Europe), and, more recently, the National Electronics Manufacturing Initiative (NEMI-US) have been aggressively seeking lead-free solutions. The automotive environment is one of the toughest since it includes chemicals both solvents and salt spray, wide temperature ranges, vibration, and humidity. A change in alloy requires extensive testing and durable materials. Tests of PWB surface finishes, Tg, and thickness will be described as they relate to lead-free solder implementation. Requirements for boards and components will also be discussed.

A round robin study for laser beam melting in metal powder bed

Abstract: With its ability to fabricate fully dense three-dimensional structures by selectively melting micro-sized metal powder, the additive manufacturing process of laser beam melting (LBM) is considered by many to be a significant technology that is complementary to the conventional forming and subtractive manufacturing processes. However, even with its ability to fabricate structures with characteristics comparable to conventional fabrication, the LBM process often lacks the consistency and degree of repeatability essential for its industrial acceptance for certain end-product applications. Inconsistency in the characteristics of structures is often related to a combination of variations in system technology, process, and user influence. In order to understand fully the potential and limitations of the LBM process, the paper discusses the design, methodology, and results of a round robin test conducted within the Collaborative Working Group (CWG) lasers in production at the International Academy of Production Engineering (CIRP). Observed mechanical characteristics for samples from each of the participants are presented. The experiments are designed to obtain data related to mechanical characteristics for different build orientations and processing conditions in addition to the inherent system technology variations. The paper further discusses the observed process phenomena and their association with the induced mechanical characteristics.

Technological complexity: A support to management decisions for product engineering and manufacturing

Abstract: Complexity is a topical interdisciplinary subject debated in different scientific circles. Complexity is difficult to univocally define as it isn't a physical quantity simple to measure but an abstract concept for which different definitions can be given. This paper deepens technological complexity applied to engineering and industrial manufacturing, focusing the related aspects that can affect a product and a production system and investigating the different measurement approaches proposed in literature, classifying them into five categories. Technological complexity is significant in product engineering development, where designers have to consider this aspect to create a functional and reliable product. Technological complexity measures are important in order to support manufacturing enterprises management in decisions concerning selection of new products to be manufactured and their production. Once a technological complexity level is defined for each product, it is possible to develop feasibility studies in order to check the plant capability to produce it.
