Nanotechnology in Cancer Therapy, load, the time spent and precision obtained in clamping the workpiece to the machine tool were of little consequence. The manually operated chucks and mandrels were used for rotating components, whereas vices and a variety of table clamps - based upon the ubiquitous T-slot - catered for stationary,

Even more dramatic than this development are the rapid advances in software engineering and electronic integration during this time and the speed of change has not abated. In fact with the advent of CNC in the 1970s, controller sophistication has con

Cutting Tool Technology, owing to the fact that even with the great advance in materials technology, these materials are of no practical use unless they can be economically fabricated into useful shapes. As it is generally accepted that around 10% of all metal produced is converted into swarf, machining remains the most common fabrication method.
