Abstract
MOSAIC-PM is based on a workstation/VME bus/Real time UNIX/C-language architecture. It is being used on a regular basis for a wide variety of demonstrations in 'intelligent systems and advanced manufacturing.' These demonstrations have included a) feature based machining, b) rapid prototyping by machining, c) networked manufacturing and d) sensor based machining. The goals of the demonstrations in sensor based machining are to improve the precision of the components being machined: i.e. to improve the capability of a 'standard' machine tool structure and give it some of the characteristics of a 'precision' machine. One routine uses a Renishaw touch trigger probe to inspect partially machined components after 'roughing'; the data collected are then used to modify the tool paths during 'finishing' to provide more precision. A second routine relies on a dynamometer to maintain constant force during cutting. This demonstration aims to achieve maximum precision by cutting at a constant force to keep tool deflection at a known value. During the demonstration, the dynamometer results are used as the feedback signal in the reference control loop of machining.
