Abstract: In a post-processing method for a workpiece, a workpiece machined by a machining device is conveyed by a robot, from the machining device to a post-processing device, information regarding a state, at the machining device, of the workpiece after machining is acquired, a processing time for post-processing of the workpiece by the post-processing device is determined by a control device on the basis of the information regarding the state of the workpiece after machining, and the post-processing is performed on the workpiece by the post-processing device for just the processing time that is determined.

Abstract: An air-blowing method includes the steps of blowing, inside a machine tool, air onto a workpiece after machining, issuing a workpiece pick-up advance notice signal for notifying beforehand of pick-up of the workpiece by a robot or a worker, on the basis of a task state of the robot or an operation of the worker, and calculating the additional time for air blow on the basis of a time required by the robot or the worker to arrive at a workpiece pick-up position in front of the machine tool after the workpiece pick-up advance notice signal is issued, where air blow is extended by just the additional time in the step of blowing air.
