Abstract
This article discusses the types and operations of the most common machines used for die threading. The construction, types, and comparison of solid and self-opening dies are discussed. The article explains the modification of chasers for threading Monel shaft. The principal factors that influence thread quality, production rate, and cost in die threading are composition and hardness of work metal; accuracy and finish; thread size; obstacles, such as shoulders or steps; speed; lead control; and cutting fluid. The article examines these factors and describes the tools and cutting fluids used for pipe threading along with the severity of stop lines.

Abstract
Forging machines use a wide variety of hammers, presses, and dies to produce products with the desired shape, size, and geometry. This article discusses the major types of hammers (gravity-drop, power-drop, high speed, and open-die forging), and presses (mechanical, hydraulic, screw-type, and multiple-ram). It further discusses the technologies used in the design of dies, terminology, and materials selection for dies for the most common hot-forging processes, particularly those using vertical presses, hammers, and horizontal forging machines. A brief section is included on computer-aided design in the forging industry. Additionally, the article reviews specific characteristics, process limitations, advantages, and disadvantages of the most common forging processes, namely hot upset forging, roll forging, radial forging, rotary forging, isothermal and hot-die forging, precision forging, and cold forging.

They are also further classified as open-die headers or solid-die headers, based on whether the dies open and close to admit the work metal or are solid. In single...
Abstract
Cold heading is typically a high-speed process where a blank is progressively moved through a multi-station machine. This article discusses various cold heading process parameters, such as upset length ratio, upset diameter ratio, upset strain, and process sequence design. It describes the various components of a cold-heading machine and the tools used in the cold heading process. These include headers, transfer headers, bolt makers, nut formers, and parts formers. The article explains the operations required for preparing stock for cold heading, including heat treating, drawing to size, machining, descaling, cutting to length, and lubricating. It lists the advantages of the cold heading over machining. Materials selection criteria for dies and punches in cold heading are also described. The article provides examples that demonstrate tolerance capabilities and show dimensional variations obtained in production runs of specific cold-headed products. It concludes with a discussion on the applications of warm heading.

In shops in which special consideration is given to dies for stainless steel, small dies (for forgings weighing less than 9 kg, or 20 lb) are made solid from hot-work tool steel, such as H11, H12, or H13. For large dies, regardless of whether they are single or multiple impression, common...
Abstract
Stainless steels, based on forging pressure and load requirements, are more difficult to forge because of the greater strength at elevated temperatures and the limitations on the maximum temperatures at which stainless steels can be forged without incurring microstructural damage. This article discusses the forging methods, primary mill practices (primary forging and ingot breakdown), trimming, and cleaning operations of stainless steels. It describes the use of forging equipment, dies, and die material in the forging operation. The article provides an overview of the forgeability of austenitic stainless steels, martensitic stainless steels, precipitation-hardening stainless steels, and ferritic stainless steels. It concludes with a discussion on the heating and lubrication of dies.

Abstract
Rotary swaging is an incremental metalworking process for reducing the cross-sectional area or otherwise changing the shape of bars, tubes, or wires by repeated radial blows with two or more dies. This article discusses the applicability of swaging and metal flow during swaging. It describes the types of rotary swaging machines, auxiliary tools, and swaging dies used for rotary swaging and the procedure for determining the side clearance in swaging dies. The article presents an overview of automated swaging machines and tube swaging, with and without a mandrel. It analyzes the effect of reduction, feed rate, die taper angle, surface contaminants, lubrication, and material response on swaging operation. The article discusses the applications for which swaging is the best method for producing a given shape, and compares swaging with alternative processes. It concludes with a discussion on special applications of swagging.

Abstract
Aluminum products such as fasteners and automotive components are often produced by cold extrusion because it facilitates high volume production of near-net-shape parts. This article describes the cold extrusion process for aluminum alloys and the associated requirements for tooling, dies, punches, and other equipment. It covers typical tool materials and their working properties, and provides best practices for sizing aluminum slugs and preparing them for use. The article also discusses the wide range of achievable shapes from shallow cup-like extrusions to deep cups and complex parts with longitudinal flutes, stems, and grooves.

Abstract
Hot extrusion is a process in which wrought parts are formed by forcing a heated billet through a shaped die opening. This article discusses nonlubricated and lubricated hot extrusion. The two nonlubricated hot extrusion methods are forward or direct extrusion and backward or indirect extrusion. The article illustrates the significance of extrusion speeds and temperatures in hot extrusion. It describes the basic types of presses used in the hot extrusion of metals. The article provides information on the characterization of extruded shapes and explains the operating parameters, including extrusion velocity, amount of pressure required, and type of lubricant, for successful and efficient hot extrusion. The article concludes with a discussion on applications and design methodology that provides insight into CAD/CAM of extrusion dies.
