Abstract

So that the many benefits arising from employing a high-speed machining strategy can be realised on conventional machining centres, companies are utilising 'speed-increasers' to elevate the rotational speed of the tooling into the high-speed range. Although such artificially-induced high peripheral speeds enable milling and drilling operations to be undertaken, this in itself causes considerable indirect problems, particularly in any contouring operation. Circular interpolation is probably the simplest form of contouring when milling, utilised for: partial arcs, blend radii, circular bosses and pockets, etc. This research examines the problems associated with using 'speed-increasers' firstly describing typical interpolation calibration procedures usin
