摘要： Methods for manufacturing a rotational non-axisymmetric lens which is manufactured by grinding using a machining tool, manufacturing a molding die for the lens, manufacturing a rotational non-axisymmetric mirror, and manufacturing a molding die for the mirror are provided. The provided methods are methods for manufacturing a rotational non-axisymmetric lens partially including a non-axisymmetric surface, manufacturing a molding die for the lens, manufacturing a rotational non-axisymmetric mirror partially including a non-axisymmetric surface, and manufacturing a molding die for the mirror. When a rotational non-axisymmetric surface is formed while scanning a surface of a workpiece by grinding or cutting means, the rotational non-axisymmetric surface is ground or cut by the grinding or cutting means while scanning the surface with movement in a direction along a meridional surface of the rotational non-axisymmetric surface.

摘要： The invention relates to a machine for processing plastic workpieces. A machine housing surrounds a working chamber located between a workpiece spindle for rotationally driving the workpieces about a workpiece axis of rotation and a fast tool servo for producing an oscillating feeding movement of a rotary tool in the direction of the workpieces. The workpiece spindle is provided with a carriage which can be driven and is guided on at least two guide surfaces of a guiding arrangement in order to produce a relative advancing movement between the workpiece and the rotary tool. The advancing movement runs transversely with respect to the feeding movement and defining therewith a processing plane in which during processing the rotary tool engages with the workpiece. The guiding arrangement is mounted on the machine housing such that the processing plane extends between the two guide surfaces.

摘要： A high bandwidth rotary fast tool servo provides tool motion in a direction nominally parallel to the surface-normal of a workpiece at the point of contact between the cutting tool and workpiece. Three or more flexure blades having all ends fixed are used to form an axis of rotation for a swing arm that carries a cutting tool at a set radius from the axis of rotation. An actuator rotates a swing arm assembly such that a cutting tool is moved in and away from the lathe-mounted, rotating workpiece in a rapid and controlled manner in order to machine the workpiece. One or more position sensors provides rotation and position information for a swing arm to a control system. A control system commands and coordinates motion of the fast tool servo with the motion of a spindle, rotating table, cross-feed slide, and in-feed slide of a precision lathe.

摘要： A lens grinding apparatus is capable of generating, in a lens blank, a power curve less than three diopters and having both a base characteristic and a cross curve characteristic. A plate is pivotably mounted on a base means, a first slide is slidably mounted on the plate, a second slide is pivotably mounted on the first slide, and a tool is mounted on the second slide for rotation about a tool axis of rotation. During a sweep of the tool across a lens blank, the position of the tool relative to the lens blank is continuously sensed to control a micro-processor. Under the control of the micro-processor, the first slide is continuously slid along the plate, and the second slide is continuously pivoted about an axis relative to the first slide. This is performed so that the sweep radius and the real head angle of the tool are continually changed in a manner maintaining a constant radius of curvature of the curve, and a constant effective head angle of the tool.

摘要： The grooved surface of an aberration-corrected holographic model grating is sensed by utilizing the sensing head of a scanning tunneling microscope. The sensing head is mechanically connected to a blazing type stylus for replicating the groove pattern of the holographic model on a ruled grating blank. A ruling engine causes the sensing head not only to scan the surface of the holographic grating model but also drive a blazing type ruling stylus or an equivalent type device in accordance with an error signal resulting from a departure of a sensing tip from the top of the holographic model groove as a function of tunneling current.

摘要： A lathe and a method of using the lathe are disclosed for forming an aspheric surface on a workpiece, in which the workpiece is mounted to a holder that is rotatably carried by the spindle, headstock and bed of a lathe, with that spindle and workpiece being rotated about the axis of the spindle with the workpiece being engaged by a forming tool which forming tool is moved through an arcuate path about an axis that is generally transverse to the spindle axis. The method and apparatus provide further for determining the time-varying angular position of the forming tool along the arcuate path, for determining the time-varying angular position of a point on the workpiece about the spindle axis and for reciprocating the workpiece holder and the workpiece held thereby relative to the lathe headstock and to the forming tool in synchronization with the movement of the forming tool and with the rotation of the workpiece about the spindle axis to form the desired contoured surface. Specified relationships are given for the movement of the workpiece holder along the spindle axis in relationship to the angle of rotation of the workpiece about its axis, the movement of the forming tool and the radii of curvature desired.

摘要： An automatic or semi-automatic lathe especially useful for producing pre-determined optical surfaces on plastic contact lenses. A collet supported on the spindle of a variable speed motor supports a lens blank in coaxial alignment with the spindle. A cutter is held in a vertically adjustable tool post mounted on one of a pair of stacked stages arranged for linear movement radial and axial of the lens blank, respectively. The other stage is mounted on a carriage which in turn is mounted on the base of the lathe and arranged for linear movement radial of the lens blank. A second variable speed motor acting through a pair of cam-operated X/Y drive mechanisms supported on the carriage drives the stages to move the cutter across and into the face of the rotating lens blank, thereby generating any desired combination of concave and/or convex optically curved surfaces. In an alternative embodiment, individual variable speed motors power the X/Y drive mechanisms through sliding wedges or the like.
