A host computer is connected to one or more machining workstations, each having its own electronic controller. Each workstation controller contains an operating machine control logic module which controls the functioning of the workstation, such as the carrying out of the movement of a chuck holding a workpiece to be machined on a spindle with respect to a tool which does the machining. Each workstation controller also contains an automation machine control logic module which automates the operation of each of the workstations. In the example of the invention described here, each automation machine control logic module contains blocks which manage the initialization of the workstation, communication between the host and the workstation controller, quality control functions, the interfacing of automated guided vehicles with the workstation, the supply of coolant to the workstation, the removal of swarf from the workstation, the status and location of the workpieces in the workstation, the supply and exchange of tools for the workstation, the logging and reporting of data, the end of part program tasks, the aborting of the part program, and tool wear and break detection and recovery of the workstation from such occurrences.
