A machine tool system and an opening stop position calculating device are provided. The machine tool system includes an openable and closable door for closing an opening of a cover surrounding a machine tool. Furthermore, the machine tool system includes an opening width setting unit for setting an opening width of the door, an opening stop position calculating unit for calculating an opening stop position of the door at which a total time, which is obtained by summing a time required to move the door from a fully closed position to a position of the set opening width and a time required to move the door from an opening stop position where the door is opened and stopped to the fully closed position, is minimized, and a door control unit for controlling opening and closing of the door based on the calculated opening stop position when exchanging the workpiece.

A universal machining system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely, and a tool turret capable of holding a variety of socketed tools. System also comprises a measurement sensor, which may be separate or comprise one of the socketed tools. A control program collects machining instructions for a series of workpieces, and directs the chuck, the tool turret, the measurement sensor, and at least one robot to load/unload workpieces and tools from the chuck and turret, respectively, measure workpieces and tools for quality control, and track available storage, overriding or skipping individual machining instructions as dictated by safety parameters and the availability of raw materials and tools.
