Book Description
Aerospace alloys such as nickel based superalloy Inconel 718 as well as titanium based T1-6A1-4V are generally regarded as difficult to cut materials. Numerous research works have been conducted on their machinability in the past few decades with the main objective of reducing cost of machining. Though classified as "difficult-to-cut" materials, they are attractive materials due to their high strength, which is maintained up to elevated temperatures and their exceptional corrosion resistance. Induction preheating is one of the new variable parameters to improve the machinability of Inconel 718 and Ti-6A1-4V. In the current work the influence of heating parameter i.e. preheating temperature; cutting variable, such as cutting speed, feed and axial depth of cut were investigated during end milling operation on a CNC Vertical Machining Center (VMC). The inserts used were TiAIN coated carbide filled onto a 20 mm diameter end mill tool. The machining experiments were conducted under room temperature and preheated conditions. Response Surface Methodology (RSM) was used to develop empirical models of tool life, cutting force and surface roughness both for room temperature and preheated machining conditions using the data generated from the machining experiments. The developed RSM models for tool life were further coupled with Genetic Algorithm (GA) to maximise metal removal per tool life by optimising the cutting conditions and preheating temperature. The comparison between room temperature and preheated machining were made in terms of tool life, cutting force, surface roughness and machine tool vibration. It was found that preheating had reduced the tool wear, surface roughness, vibration/chatter amplitudes and chip formation stability to a desired level.

Book Description
This book presents a collection of examples illustrating the resent research advances in the machining of titanium alloys. These materials have excellent strength and fracture toughness as well as low density and good corrosion resistance; however, machinability is still poor due to their low thermal conductivity and high chemical reactivity with cutting tool materials. This book presents solutions to enhance machinability in titanium-based alloys and serves as a useful reference to professionals and researchers in aerospace, automotive and biomedical fields.

All of the critical technical aspects of gear materials technology are addressed in this new reference work. Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.
