Abstract: A welding machine manipulated by automated equipment controls feeding of depositing metal independently of controlling a welding current, so that the welding can be finely controlled and quality welding is achievable. The welding machine includes a robot having an arm for moving a welding torch, a robot controller for controlling the movement of the robot, a welding power source coupled to the torch, a depositing metal feeder for feeding depositing metal to the welding torch, and a feeder controller for controlling the feeder. The robot controller is coupled to the feeder controller for transmitting a control signal, related to feeding the depositing metal, to the feeder controller.

Abstract: A numerically controlled machine tool is provided which comprises an operation control unit with an operating panel having key switches disposed thereon whereby data on the finish shape and finish dimensions of a workpiece and the machining conditions including spindle rpm and feed rate can be transferred into a control unit. On the basis of this input, the control unit automatically prepares a processing program which decides on the amounts and directions of movement of the tool rest longitudinally and transversely from a reference point which is inherent in the machine and controls the movement in accordance therewith so as to automatically machine the workpiece to the predetermined shape and dimensions.
