This chapter addresses the hardware requirements for filament winding, from elementary processing equipment to more advanced systems. The chapter describes the equipment, defines how it is best used, and presents real-life examples. It describes a helical horizontal filament winding machine system and a vertical winding machine. The chapter provides information on in-plane (polar) winders and several types of creels, namely stationary and no twist, rotating, braking, and combinations thereof. Comprehensive descriptions of mandrel designs used in filament winding are presented in text and illustration. The chapter also reviews process control of filament winding parameters, including for some specialized winding processes and unique component types.

The necessity of developing the lightest-weight structures with sufficient strength was the driving factor for the development of filament-wound composite pressure vessels. This chapter presents a brief history of the development of rocket motor cases (RMCs), followed by a comparison of the advantages of composites over metals for RMCs. A discussion on a typical design, analysis, and manufacturing operation follows. The chapter introduces the basic design approach and shows some sizing techniques along with example calculations. It discusses the processes involved in the testing of the composite pressure vessel.

This chapter begins with a review of some of the terms used in the gear industry to describe the design of gears and gear geometries. It then discusses the types of gears that operate on parallel shafts, intersecting shafts, and nonparallel and nonintersecting shafts. Next, the processes involved in the selection of gear are discussed, followed by information on the basic stresses applied to a gear tooth, the strength of a gear tooth, and the most widely used gear materials. Further, the chapter briefly reviews gear manufacturing methods and the heat treating processing steps including prehardening processes, through hardening, and case hardening processes.

Gear manufacture depends on machinery available, design specifications or requirements, cost of production, and type of material from which the gear is to be made. This chapter discusses the processes involved in methods for manufacturing gears, namely casting, forming, and forging.

This chapter focuses on the design of measuring devices. The devices used to measure vibration typically consist of an electronic transducer with an interconnecting cable and an alternating current voltmeter. The working principle of each type of transducer is described in this chapter along with their important characteristics and common applications. The chapter provides general guidelines for the selection of a measuring device, and discusses vibration severity levels.

The objective of mechanical testing of an engineered material is to provide data necessary for the analysis, design, and fabrication of structural components using the material. The testing of filament-wound composite materials offers unique challenges because of the special characteristics of composites. This chapter describes suitable static mechanical test techniques for characterizing laminated composite materials. The approach is to provide recommended techniques, based on consensus opinions of fabricators and users of filament-wound composites, and to survey available techniques that have been used successfully in the field. The chapter describes the effects of various factors on the properties of composite constituents, including fibers, resins, and unidirectional plies. Some aspects of specimen selection are also described. The chapter provides information on pressure bottles and tubular parts that have been developed as standard test specimens for combined load testing of composites.

Induction heat treating is used in a wide range of applications. Typical uses, as described in this chapter, include the surface hardening of many types of shafts as well as gears and sprockets and the through-hardening of gripping teeth, cutting edges, and impact zones incorporated into various types of tools and track pins manufactured for off-highway equipment.

This chapter reviews various ways to classify failure categories and summarizes the basic types, causes, and mechanisms of damage, with particular consideration given to whether the likelihood of the types of damage can or cannot be influenced by the heat treating of steel parts. The classical organization for types of damage (failures) is as follows: deformation, fracture, wear, corrosion or other environmental damage, and multiple or complex damage. The chapter also provides some examples of lack of conformance to specification that may at first look like the heat treater did something wrong, but where other contributing factors made it difficult or impossible for the heat treater to meet the specification.

This chapter explains how to join beryllium parts using adhesive bonding and mechanical fastening techniques and discusses the advantages and disadvantages of each method. It describes the stresses that need to be considered when designing adhesive bonds, the benefits and limitations of different adhesives, and surface preparation requirements. It explains how adhesives are applied and cured and how curing times and temperatures affect bonding strength. It also discusses the use of bolts and rivets and the different types of joints that can be made with them.

Iron and steel have been the most useful materials to meet the needs of several industries for many decades. Each iron and steel alloy offers unique attributes that make them the best choice for an application. This chapter provides an overview of each ferrous alloy—gray iron, malleable iron, compacted graphite iron (CGI), ductile iron, austempered ductile iron (ADI), and carbon steel and low-alloy steel; its versatile attributes; and its individual applications. A large section of the chapter covers the impact of electric vehicles on the future of the iron and steel castings industry, including discussion on electric vehicle categories and weights; impact of center of gravity on stability and steering; lightweighting incentives; and engineering for improved suspension.

This appendix is a glossary of terms and definitions associated with sheet metal forming.

Steel castings are produced in thousands of designs for different applications. They fill needs in many industries, including transportation, construction machinery, earthmoving equipment, rolling mills, mining, oil and gas exploration, and power generation. This chapter touches upon the variety of applications for which steel castings can be supplied and the ranges of casting size and complexity. Photographs in this chapter provide an understanding of these applications, their size and complexity, and the types of cast steels produced.

This chapter focuses on the causes of gear failure under five major headings. These include basic material, focusing on steel, engineering, focusing on the integration of design, manufacturing, heat treatment, and service application.

Because of its speed and ease of control, induction heating can be readily automated and integrated with other processing steps such as forming, quenching, and joining. Completely automated heating/handling/control systems have been developed and are offered by induction equipment manufacturers. This chapter deals with materials handling and automation. First, it summarizes basic considerations such as generic system designs, fixture materials, and special electrical problems to be avoided. Next, it describes and provides examples of materials-handling systems in induction billet heating, bar heating, heat treatment, soldering, brazing, and other induction-based processes. The final section discusses the use of robots for parts handling in induction heating systems.

Surface modification technologies improve the performance of tool steels. This chapter discusses the processes involved in oxide coatings, nitriding, ion implantation, chemical and physical vapor deposition processing, salt bath coating, laser and electron beam surface modification, and boride coatings that improve the performance of hot-work and high-speed tool steels.

Unlike conventional quench and temper heat treatment, austempering is an iron and steel heat-treatment process that enhances mechanical properties through the isothermal transformation of austenite with a minimum amount of quenching stresses. This chapter begins with a discussion of austemperability requirements. Then outlines of austenitizing and austempering cycles and resultant microstructures are presented. This is followed by sections discussing the mechanical properties, advantages, limitations, machinability, process variants, and applications of austempered ductile iron (ADI). Information on the growth of premachined ADI components is also provided. Further, the chapter describes two slightly different systems for austempering: atmospheric-salt and salt-salt systems. Finally, it presents general guidelines for component designers, casting manufacturers, and heat treaters to apply ADI more widely and with improved success.
