Process Control for Sheet-Metal Stamping is a comprehensive and structured approach to the design and implementation of controllers for the sheet metal stamping process. The use of process control for sheet-metal stamping greatly reduces defects in deep-drawn parts and can also yield large material savings from reduced scrap. Sheet-metal forming is a complex process and most often characterized by partial differential equations that are numerically solved using finite-element techniques. In this book, twenty years of academic research are reviewed and the resulting technology transitioned to the industrial environment. The sheet-metal stamping process is modeled in a manner suitable for multiple-input multiple-output control system design, with commercially available sensors and actuators. These models are then used to design adaptive controllers and real-time controller implementation is discussed. Finally, experimental results from actual shopfloor deployment are presented along with ideas for further improvement of the technology. Process Control for Sheet-Metal Stamping allows the reader to design and implement process controllers in a typical manufacturing environment by retrofitting standard hydraulic or mechanical stamping presses and as such will be of interest to practising control engineers working in metal-working, automotive and aeronautical industries. Academic researchers studying improvements in process control and how these affect the industries in which they are applied will also find the text of value.
"A Fortune in Scrap - Secrets of the Scrap Metal Industry" written by industry veteran, Ken Burtwell, describes how reclamation is vital to the national economy and ranks high on the list of the nation's largest industries. We're not talking recycling plastic bottles and aluminum cans here - sure, that's something all of us can do, but what the average person doesn't know is the "hidden scrap" that's not obvious to the casual observer - and when salvaged properly - is worth a fortune! Ken shows you how to identify different metals with magnets and chemical tests and you'll learn how to prepare them for sale to get the BIGGEST BUCKS possible. Prep tools such as "Flame Cutting" and the awesome power of the "Thermic Lance" are described. From bridges and old buildings to old locomotives and the rails they run on, Ken covers this and shows you his (old) photos of buildings being demolished and their hidden gems. This is an example of BIG RECYCLING, and is a necessary process both from an economical and environmental point of view as there is a reduced demand on the Earth's natural resources. Included are formulas for estimating weights of steel drums, and tables showing weight-per-pound for different metal thicknesses. After reading Ken's "A Fortune in Scrap," you'll agree that recycling today is BIG BUSINESS and those having the moxie to forge ahead will be well rewarded. Topics covered in the book are: - Steel - The Scrap Dealer or Collector - Flame Cutting Steel Scrap - Better Grade - More Value - Metal Scrap from Demolition - The Thermic Lance (aka Thermal Lance) - Railroads and Rail Vehicles - Reclamation Equipment - Sheet Steel Gauges and Weights - More Valuable Scrap Metals - Common Metals: Lead And Zinc - Less Common Metals and Where To Find Them - Identification of Metals - Magnetic Testing - Government Scrap Sales - Precious Metals - Silver Coins - Testing Various Metals - Scrap Dealers THANK YOU for reading the description of this very interesting book and we hope you enjoy your purchase. Please feel free to leave a review as this aids others greatly in their purchasing decision.
Most publications on heavy metals and the environment have focused on environmental pathways and risks. The present book establishes a link between the environmental risks of heavy metals and the societal causes of the risks. Economic models, substance flow models and environmental fate and risk assessment models have been integrated into a single analytical framework that has been used to trace and understand the routes by which four heavy metals enter the economy, through to their final destination in the environment. The long-term impacts of the current metals management regime in the Netherlands have been used as a case study by which to assess the effectiveness of certain policy measures.
