A control device for controlling a machine tool, wherein the machine tool and the control device are configured such that a tool and/or workpiece disposed on the machine tool can be moved with at least one first speed and at least one second speed. When switching from a movement with the first speed to a movement with the second speed, the tool or the workpiece is at first stopped prior to the execution of the movement with the second speed, if the second speed is greater than the first speed by at least a predetermined factor. The control device has an input device for triggering the movement with the second speed, and the subsequent execution of the movement with the second speed is triggered by an operator input on the input device. A corresponding control method for controlling a machine tool is also described.

A machine tool system includes a machine tool main body for machining a workpiece supported on a table by using a tool detachably attached to a spindle, and an information processing apparatus. The machine tool main body includes a rotary tool magazine in which multiple grips each capable of holding the tool to be attached to the spindle are provided along the circumferential direction, and an image pickup device that is arranged in the tool magazine and configured to take an image of multiple members in a machining area of the machine tool main body.

Computer-implemented methods and systems for feeding workpieces to a manufacturing line are provided. An example method involves operating at least one processor to: receive, from at least one image device proximal to a bowl feeder, a sequence of images of workpieces within the bowl feeder; determine a flow velocity of the workpieces within the bowl feeder; generate bowl feeder control settings by applying the flow velocity to a predictive model; and automatically apply the bowl feeder control settings to the bowl feeder. Computer-implemented methods and systems for predicting anomalies in a manufacturing line are also provided. An example method involves operating at least one processor to: receive a sequence of images of workpieces in the manufacturing line; extract feature data from the sequence of images; apply the feature data to a predictive model to detect anomalies in the manufacturing line; and generate annotations to locate the anomalies within the images.

In a method for automated positioning of a blank in a processing machine provided with a housing and a spindle unit with an electric motor, a control unit for control and electrical supply of the processing machine, a computer producing processing programs for manufacturing workpieces, a workpiece holder, and an image recording unit that optically records image data of a blank received in the workpiece holder, a blank is fixed in the processing machine and the image recording unit produces an image of the blank. A division of the blank into an already processed region and into an unprocessed region based on the image data of the image is performed. A workpiece geometry to be produced is assigned to the unprocessed region of the blank, and a milling operation is performed on the unprocessed region. In a variant of the method, the image recording unit is separate from the processing unit.
