A machine tool and a control apparatus thereof include an amplitude control unit to control the amplitude of reciprocal vibration by a vibration unit. The amplitude control unit is configured to reduce the amplitude of the reciprocal vibration by the vibration unit as a cutting tool is fed in a feeding direction when the cutting tool reaches a predetermined cutting tool work stopping position on a workpiece in the feeding direction (Z-axis direction) to prevent the cutting tool from cutting the workpiece beyond the cutting tool work stopping position.

A work piece processing device includes a work piece processing head supported by an actuator including one of a servo actuator, a pneumatic actuator, a hydraulic actuator, an electric actuator, and a chain drive actuator. A controller uses two or more parameters concurrently in the controls of the work piece processing head and the actuator. According to a further aspect, the controller uses a time duration in the controls in conjunction with a predetermined parameter.

A blank for manufacturing molded dental components includes a blank body that includes tooth repairing material. A molded dental component is manufactured by removing portions of the tooth repairing material using a tool. The blank is encoded with at least one structure as a carrier of information regarding properties of the blank body. The at least one structure is arranged such that at least one of a position, dimensions, or a type of structure can be determined by sensing or measuring the blank. In this context, the position, the dimensions, or the type of the structure are embodied such that a value acquired during a determination of the above corresponds to information about a property of the blank body.

Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

A sensor apparatus for detecting a target object influenced by a process or formed in the process includes a sensor unit and an evaluation device. The sensor unit detects the target object in a detection zone of the sensor unit and generates a sensor signal that can be influenced by the target object. The evaluation device processes the sensor signal as a first input variable and generates an output signal, which indicates the detection of the target object, in dependence on the sensor signal. The evaluation device further processes a process parameter of the process, which acts on the target object, or a target object parameter, which characterizes the target object and is influenced by the process, as a respective further input variable and to generate the output signal in dependence on the process parameter and/or the target object parameter.

A transmission arrangement for energy and/or signal transmission between a control unit of a machine tool and at least one electronic component, in particular for use in a machining center or a turning and/or milling center. The transmission arrangement is configured to transmit energy and/or signals between electronic components arranged on a pallet and a control unit of a machine tool. The method shows a procedure for automated machining of a workpiece by means of a machine tool, in particular when electronic components are arranged on a pallet on which the workpiece is clamped.

A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.
