摘要:
A machine tool having a tool magazine for tools, which the machine tool can hold one at a time in order to machine a workpiece is provided. A method for controlling the machine tool includes steps of detecting workpieces to be machined and grouping detected workpieces into set-up families in such a way that a set-up associated with the set-up family is sufficient for machining the workpieces belonging to the set-up family. The set-up includes tools, which can be simultaneously loaded in the tool magazine, and the set-up families are formed in such a way that the number of tools that must be loaded in order to machine the detected workpieces is minimized as far as possible.

An optimal process determining system executes a step of calculating a temporary process that includes information of a plurality of individual processes. According to an example, each process includes a tooling including of a tool, a holder, a tool projection length, and a sequence of the plurality of individual processes. A similarity between the toolings of two individual processes is calculated. In addition, a calculation is performed relating to a plurality of integrated processes for which the tooling of one of the individual processes having a high similarity is integrated into the tooling of the other one of the individual processes. In addition, an optimal process is determined from the plurality of integrated processes on the basis of an actual machining time in each of the integrated processes, a unit integration reduction time reduced as one of the toolings of the individual processes is integrated, and the number of the individual processes integrated.

A dispatch integration method based on semiconductor manufacturing. When multiple tools are idle, idle messages are sent to a real-time dispatch system through a tool control system and a manufacturing execution system. The real-time dispatch system sorts tool parameters relating to tool efficiency based on a currently executed process using a principal component analysis method, defining weights of each tool according to the defined tool parameters and corresponding factor weights using a linear regression weight formula, calculating tool weights of each tool parameter using a linear regression weight formula, and determining a desired tool for dispatch according to the calculated tool weights.

摘要:
A method for reducing retooling costs, particularly relative to painting processes for vehicles. The method includes dividing the order into groups based on color, painting them in color order, and then sequencing them into the original build order. If a paint defect occurs on a vehicle, then it is removed from the optimized product order sequence and repaired. Upon completion of the repair, the repaired vehicle is reinserted back into the optimized product sequence to be repainted. Between each different color, a paint purging process occurs.
