Abstract
A machine tool method employs a plurality of tools which may be sequentially or simultaneously automatically controlled to perform preprogrammed operations by either the same or different workpieces. A unit of work is conveyed to be operated on by selected of the plurality of tools that are controllably operated at respective work locating positions. A plurality of command control message signals are generated to perform preprogrammed operations either in sequence or simultaneously on the same workpiece or simultaneously on separate workpieces spaced apart on a common conveyor such as a flight conveyor while the conveyor is either in motion or stationary. In another form, the conveyor is automatically stopped with units of work thereon, each disposed so as to be predeterminately located with respect to a respective machine tool which has been prepositioned adjacent the work-holding conveyor. In yet another form, at least certain of the machine tools are movable parallel to the work-holding conveyor so that they may be predeterminately moved prior to and/or during operations on work. In yet another form, means are provided for transferring units of work from the work-holding conveyor to temporary platforms adjacent certain of the respective machine tools so that each tool may perform automatic operations on work while the work-holding conveyor remains operating.
