  • The Norwich Gun Industry
    salzer_40_47 2/14/05 3:17 PM Page 40 The Norwich Gun Industry Dick Salzer New England and, especially, Connecticut have been and remain the center of the American gun industry ever since the days of the American Revolution. Gun makers orig- inally were attracted to Connecticut because of that state’s many assets—year-round water power, a skilled industrial labor base, good ports and rail lines, and proximity to the major population centers of New York and Boston—all of these contributed to that centralization. These factors were especially prevalent at Norwich. The City of Norwich was founded in 1659. By the time of the American Revolution, it had grown to become one of the 10 largest cities in the Colonies.1 It was richly endowed with all of those assets desirable in a manufacturing site, not the least of which was the confluence of the Shetucket and Yantic Rivers, which merged at Norwich to form the navi- gable Thames River. As a large city by the standards of the breadth of the Norwich arms industry during its golden day, it offered sources of capital, a diverse population of years. skilled workers, support industries, and easy access to the This presentation will focus largely on the period New York and Boston markets through its sheltered port starting in the 1840’s when conditions were exactly right and rail lines. for the incubation of the arms industry.

  • Unit 22: Fabrication Processes and Technology
    Unit 22: Fabrication Processes and Technology Unit code: L/600/0273 QCF Level 3: BTEC Nationals Credit value: 10 Guided learning hours: 60 Aim and purpose This unit aims to give learners a knowledge of the processes used to safely measure, mark out, cut, form and assemble fabricated structures using sheet metal. Unit introduction Fabrication processes and technology are used in the production of metal structures in a wide range of manufacturing industries. The fabrication of metal structures involves four essential stages: measuring and marking out, preparation of the material for fabrication, forming processes and the assembly of the materials. This unit gives learners with no previous fabrication experience an understanding of the processes and technologies used throughout the fabrication industry, whilst learning to work in a safe environment. The unit is appropriate for work-based learners or for those who are being prepared for employment in an industrial environment where fabrication is an integral part of the manufacturing process. Learners will work with ferrous or non-ferrous metals in the form of sheet, plate and sectional materials to construct a fabricated structure. They will learn how to use a range of industrial hand tools and machinery to complete fabrication tasks. The unit will give learners the ability to identify the correct processes and equipment to use, and the tools and equipment appropriate to each stage of the fabrication process. Learning outcomes On completion of this unit a learner should: 1 Know about health and safety legislation, regulations and safe working practices in the fabrication industry 2 Know the processes used to mark out and prepare materials to produce fabricated structures 3 Know how materials are formed and assembled to produce fabricated structures 4 Be able to interpret the specification of a fabricated structure and plan and carry out its manufacture.

  • A Novel NDT Method for Measuring Thickness of Brush-Electroplated
    17th World Conference on Nondestructive Testing, 25-28 Oct 2008, Shanghai, China A Novel NDT Method for Measuring Thickness of Brush-Electroplated Nickel Coating on Ferrous Metal Sueface Shiyun DONG 1, * , Binshi XU 1 , Junming LIN 2 1 National Key Laboratory for Remanufacturing, Beijing 100072, China 2 Eddysun (Xiamen) Electronic Co., LTD., Xiamen, Fujian, 361004, China * Tel: +86-10-66718541, Email: [email protected] Abstract Brush-electroplated nickel coating has been widely applied to repair and remanufacture ferrous metal component. Generally, the nickel coating has thickness from 0.05 mm to 0.2 mm, and it is also ferromagnetic like iorn metals. Therefore, the traditional supersonic thickness tester and eddy current thickness tester are not competent to measure the nickel coating thickness on iron or steel metal surface, and the brush-electropalted nickel coatings are still lack of NDT method to measure its thickness. In this paper, a novel NDT method for the brush-electroplated nickel coating thickness measuring was investigated on eddy current mechanism. A series of brush-electroplated nickel coatings with various thickness were prepared on SUS1045 steel, whose thickness was confirmed on cross-section with SEM or optical microscope. Then Eddy signals of the coatings was tested, and a fitted relationship between the eddy signal phase and the thickness was found for the nickel coatings. Based on this results, a novel NDT method to measure the nickel coating thickness was set up, which could give precise resuts and be operated simply. Therefore, the method shows wide application in engineering. Key words ：eddy current, brush-electroplated nickel coating, coating thickness, NDT 1.

    UNIT 3 PRESS AND PRESS TOOLS Press and Press Tools Structure 3.1 Introduction Objectives 3.2 Press 3.3 Types of Presses 3.4 Main Parts of Typical Power Press 3.5 Specifications of a Press 3.6 Press Tool 3.7 Die Set and its Details 3.8 Methods of Die Supporting 3.9 Classification of Dies 3.10 Important Consideration for Design of a Die Set 3.11 Summary 3.12 Answers to SAQs 3.1 INTRODUCTION Metal forming is one of the manufacturing processes which are almost chipless. These operations are mainly carried out by the help of presses and press tools. These operations include deformation of metal work pieces to the desired size and size by applying pressure or force. Presses and press tools facilitate mass production work. These are considered fastest and most efficient way to form a sheet metal into finished products. Objectives After studying this unit, you should be able to understand introduction of press tool, major components of press working system, different criteria of classification of presses, different types of presses, description of important parts of a press, specifications of a press, other press working tools, like punch and die, components of press working system, different types of die sets, and design considerations for die set design. 3.2 PRESS A press is a sheet metal working tool with a stationary bed and a powered ram can be driven towards the bed or away from the bed to apply force or required pressure for various metal forming operations. A line diagram of a typical pres is explained in the Figure 2.1 hydraulic system.

    INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1. The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)” . If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete.
