CNC Machining Technology

This is the second volume of three designed to give an insight into the current state of CNC technology with a focus on practical applications. Following a brief historical introduction to cutting tool development, chapters 1 and 2 explain why CNC requires a change in cutting tool technology from conventional methods. A presentation is given of the working knowledge of cutting tools and cutt ing fluids which is needed to make optimal use of the productive capacity of CNC machines. Since an important consideration for any machine tool is how one can locate and restrain the workpiece in the correct orientation and with the minimum of set-u p time, chapter 3 is concerned with workholding technology. The author draws on his extensive experience as a practitioner and teacher. The text is thoroughly practical in character and generously illustrated with diagrams and photographs.
