For example, if a new tool is used on a machine tool 22, then a certain number of parts will be ejected after initial machining by this new tool. Damaged parts, whereby the damage can be recognized in particular by the testing device 72, are likewise conveyed to the central device 16 and discarded there.
• the arrangement of machine tools of different work sequence devices 20 in a strand such as the first strand 24 also results in increased variability of the manufacturing system.
• machine tools in the example of FIG. 1, by way of example, a machine tool 90 of the work sequence device 20e
• different work sequence devices in the example shown also in the work sequence device 20d
• the work content per work sequence device 20 is defined so that manufacturing conditions are met and the duration per work sequence device 20 an integer multiple of the
• the machine tool 90 is used variably in this work sequence device.
• buffer memory 88 By buffer memory 88, an optimized total availability can be achieved.
