  • In this paper, a novel and complete process to simulate an active vibration control system in a centerless grinding machine is presented. Based on the updated finite element (FE) model of the machine, the structural modifications performed to incorporate active elements are detailed, as well as the subsequent reduction procedure to obtain a low-order state space model.

  • Improved manufacturing productivity, over the last 50 years, has occurred in the area of machining through developments in the machining process, in machine tool technology and in manufacturing management. The subject of this book is the machining process itself, but placed in the wider context of manufacturing productivity. It is mainly concerned with how mechanical and materials engineering science can be applied to understand the process better and to support future improvements.

  • This book, based on intensive research I have conducted since the late 1970s, is my attempt to cover in one monograph the modern theory of surface generation with a focus on kinematic geometry of surfacemachining on amultiaxis numerical control (NC) machine. Although the orientation of this book is toward computer-aided design (CAD) and computer-aidedmanufacturing (CAM), it is also useful for solving problems that relate to the generation of surfaces on machine tools of conventional design (for example, gear generators, and so forth)....

  • Drilling operations are perhaps the most popular machining process being undertaken today, with their origins being traced back to cutting tool developments in North America in the 19th century. In 1864 toward the latter part of the American Civil War, Steven Morse (i.e. later to design the significant ‘Morse taper’ – for accurate location of the ‘sleeved drills’ into their mating machine tool spindles) founded the Morse Twist Drill and Machine Company in the ‘North’.

  • A lathe is a machine tool which spins a block of material to perform various operations such as cutting, Turning, Facing, Threading, sanding, knurling, drilling, or deformation such as metal spinning with tools that are applied to the work piece to create an object which has symmetry about an axis of rotation .Lathe Machine: • The term Centre Lathe is derived from the fact that in its operation the lathe holds a piece of material between two rigid supports called centres, or by some other device such as a chuck or faceplate which revolves about the centre line of the lathe. .Lathe...

  • (BQ) This paper is devoted to a study of the influences of EDM parameters on surface roughness for machining of 40CrMnNiMo864 tool steel (AISI P20) which is widely used in the production of plastic mold and die. The selected EDM parameters were pulsed current (8, 16 and 24 A), pulse time (2, 3, 4, 6, 12, 24, 48 and 100 s) and pulse pause time (2 and 3s). It was observed that surface roughness of workpiece and electrode were influenced by pulsed current and pulse time, higher values of these parameters increased surface roughness.

  • The basic engine lathe, which is one of the most widely used machine tools, is very versatile when used by a skilled machinist. However, it is not particularly efficient when many identical parts must be machined as rapidly as possible. As far back as 1850 there were efforts to develop variations of an engine lathe that could be operated by a relatively unskilled

  • Michael Faraday?s early metallurgic researches, from 1818 to 1824, anticipated the developments which have led to widespread use today of alloy steels. Much effort has been expended to improve their performance for their service as cutting tools in machining. The aim has always been to yield higher rates of machining and to tackle recently developed harder materials on the principle that the tool material must be harder than the workpiece which is to be machined.

  • The machining of complex sculptured surfaces is an important technological topic in modern manufacturing, namely in the molds and dies sector. Today, this sector, with great importance to automotive, aircraft and others advanced industries, is placed in all industrialized or emerging countries. In the recent past, the traditional technology employed in molds and dies manufacture was a combination of con- ventional milling and electro-discharge machining (EDM) or electrochemical machining (ECM).

  • The modular tooling concept was developed by cutting tool manufacturers from the long-standing tooling cartridges (Fig. 112 – indicates a typical self-contained cartridge), which had been previously available for many years. Initially, the modular tooling was designed and developed for turning operations (Fig. 113) and was demonstrably shown to offer amazing versatility to a whole range of machine tools and, not just the CNC versions.
