The purpose of this writing is to report the present status of development and implementation of the SPAC Module. The SPAC Module was originally conceived two years ago, and the justification for its development is just as valid today as it was then. Actually, our increasing experience in operating a service center for NC Lofting has provided additional reasons for generating other computer outputs not conceived originally to reduce lofting man-hours and better control schedules, as shown later. It should be mentioned at this point that the labeling capabilities added to the SPADES System in general because of the SPAC Module will make it desirable to upgrade the hardware used in the loft and in the shop. A fast drafting machine should be used in those shops with a high work load, and a DNC mode of operation will allow not to punch a high volume of paper tape. Provisions have also been made for transferring all applicable labeling and lofting markings to the burning machine. To do so today for all tapes will probably overload the burning machine. I feel that the use of this feature is justifiable at the present only when using the burning machine for cutting templates from light gauge sheet metal or aluminum, since this operation will represent only a small percentage of the total work load. Total use of it will probably have to wait until better marking systems are available, although some shipyards with surplus NC cutting capability might find it desirable, even with todays hardware. The zinc oxide marker is probably the best tool to use at the present for this purpose.
