摘要： A method of machining a workpiece using a machine tool, the machine tool comprising a tool mount carrying a tool, a workpiece mount carrying a workpiece, a drive mechanism for moving at least one of the tool mount and the workpiece mount relative to the other, and a control arrangement for controlling the drive mechanism. The method comprises moving at least one of the tool mount and the workpiece mount with the drive mechanism under the control of the control arrangement so that the tool contacts a portion of the workpiece to commence a machining operation, and the tool then removes material from the portion of the workpiece until completion of the machining operation, the movement being such that the relative velocity between the tool and the workpiece decreases continuously during the majority of the time that the tool and the workpiece are in contact with each other during the machining operation.

摘要： A sensor for monitoring a conductive film in a substrate during chemical mechanical polishing generates an alternating magnetic field that impinges a substrate and induces eddy currents. The sensor can have a core, a first coil wound around a first portion of the core and a second coil wound around a second portion of the core. The sensor can be positioned on a side of the polishing surface opposite the substrate. The sensor can detect a phase difference between a drive signal and a measured signal.

摘要： A polishing apparatus comprises a polishing member for polishing a workpiece and a manipulator for manipulating the workpiece and having a base disposed at a coordinate origin of a base coordinate system. The polishing member and workpiece define therebetween a contact surface having a contact surface coordinate system relative to an initial coordinate system defined when the polishing member and the workpiece initially contact one another at the contact surface but before a force is exerted on the contact surface to polish the workpiece. A first control device successively updates a position and attitude of the contact surface coordinator system with respect to the initial coordinate system on the basis of a deviation between preselected values of force and moment acting on the workpiece and detected values of force and moment acting at the contact surface between the polishing member and the workpiece when a force is exerted on the contact surface to polish the workpiece. A second control device successively updates a position and attitude of the contact surface coordinate system with respect to a coordinate system corresponding to the workpiece by changing a position and attitude of the workpiece. The calculating device calculates a position and attitude of the manipulator on the basis of the updated results of the first and second control devices and a position and attitude of the initial coordinate system with respect to the base coordinate system. The driving device drives the manipulator to manipulate the workpiece on the basis of the calculation results of the calculating device.

摘要： An electric control apparatus for an industrial robot the arm of which is actuated to carry out machining of a workpiece by means of a machining tool attached thereto. The control apparatus includes a force sensor arranged to detect reaction force acting on the tool, a memory for memorizing a maximum reaction force detected by the sensor during each machining process of the workpiece in a plurality of split sections of a teaching line, a comparator for comparing the memorized maximum reaction force with a set value indicative of a limit of reaction force acting on the tool and for producing a signal therefrom when the memorized maximum force exceeds the set value. The control apparatus is arranged to operate the robot in such a manner that the machining tool is moved along the teaching line to successively carry out machining of the workpiece in the split sections and is further arranged to ascertain as to whether or not the comparator produces the signal therefrom at each time when the tool arrives at each terminal point of the split sections for producing a control signal therefrom when applied with the signal from the comparator, thereby operating the robot in response to the control signal in such a manner that the machining tool is returned to each start point of the slipt sections to repeat deburring in the same section.

摘要： A method and apparatus for machining a custom-shaped dental restorative part from a blank of dental material yield the entire part in a single operation, and include a workpiece being mounted on a support member which facilitates rotation and axial movement of the workpiece. A separating disk is used for almost the entire machining operation, and an additional tool in the shape of a burr can optionally be provided to shape more elaborate pieces. The disk and burr are supported by a tool holder which is supported for movement parallel to and rotationally about an axis. The disk and burr are powered by a closed loop fluid supply arrangement. A tool velocity sensing scheme is utilized for adaptive feed and to compensate for tool wear. The machining mechanism and associated control circuitry are enclosed in a common cabinet so as to provide a mobile unit suitable for use in a dentist's office.
