According to one of today's most accepted visualizations of the first viable realizations of The Computer Integrated Manufacturing Plant, C.I.M.P., the manufacturing systems herein discussed tend to be multiprocessing, and tend to incorporate the lasers to take advantage of the unique capacities of the laser as a processing tool. Finally also the present laser sources, while having been for a long time more than sufficient, inevitably tend also to new generations. Said visualizations stand in the belief that the first realizations of the C I M P most likely will use flexible multiprocessing machines, which, for flexibility requirements, grow in multi-station cells, in their aggregation in isles and finally in complete manufacturing centers. To constitute the CIMP all partaking elements must be the most easily amenable to Computer Aided Design, CAD, and Computer Aided Manufacturing, CAM. Another basic requirement is that all elements constituting the CIMP must possess the highest System Efficiency and Energy Efficiency at the level of the single element and of its aggregations throughout the various combinations at each and every operating level of said aggregations, up to that of the CIMP. The mastering of the CIMP design constitute a New Discipline that presents very formidable but necessary tasks. Of these the first examples were those related to the early flexible manufacturing system Design Programs. For what concerns the laser processing machines and their integration in manufacturing systems, attention must be given to not repeat the events that hindered their diffusion in the production field keeping it at a level much lower than the expectations and their true potential. Said events stemmed from the confusion between System Efficiency and Energy Efficiency, which persisted for too long and is still common. This has taken place at the levels of introduction of a single element into the combination of the several elements constituting a linear arrangement such as a Transfer Production Line. It because greater and with graver consequences in the case of arrangements possessing more than one degree of product routings, arrangements, as previously mentioned, which evolved in the Flexible Manufacturing Centers.
