Advances in Machine Tool Design and Research 1967, Part 2 provides information pertinent to the development of machine tool design. This book discusses the advances in pneumatic positioning device in the machine tool laboratories. Organized into 41 chapters, this book starts with an overview of the pneumatic digital and analogue elements used in designing the control loop. This text then explains the control system for the cylindrical grinding process developed by fluid logic elements and the diaphragm-type fluid logic element used in the control system. Other chapters consider the causes of inaccuracies on a finished machined workpiece produced by a numerically controlled machine tool. This book discusses as well the machine errors that are corrected by instrumentation, the details of this installation, and the characteristics of the instrumentation required. The final chapter deals with the basic characteristics of material flow during closed die forging. This book is a valuable resource for production and mechanical engineers.
