    Abstract: The movement position of the roughing tool is calculated, in S109, by adding the finishing allowance to the movement position of the finishing tool so that the path of the roughing tool is shifted in the direction perpendicular to the rotation center axis of the main spindle rotation motor from the path of the finishing tool by the finishing allowance. Then, a gap between the movement position of the roughing tool in the direction of the rotation center axis of the main spindle rotation motor and the workpiece W is calculated, and when the gap is not larger than a predetermined value G, in S113, the movement position of the roughing tool is corrected in the direction perpendicular to the rotation center axis of the main spindle rotation motor so that the roughing tool does not cut in the inside of the finishing portion of the workpiece. The movement position of the roughing tool is corrected so that the movement speed of the roughing tool in the direction perpendicular to the rotation center axis of the main spindle rotation motor is a predetermined value.

    Abstract: A gear grinding machine and a gear grinding method, in which a gear-shaped grinding stone is caused to engage a gear-like workpiece and one of the gear-shaped grinding stone and the gear-like workpiece is reciprocated relatively to the other in axial direction thereby to grind the tooth flanks of the workpiece, are disclosed. The rotational resistance is applied by a brake unit to the rotationally driven side. The grinding resistance and the rotational resistance interfering with the relative reciprocal motion are detected by torque sensors and input to a control unit, the average value of each of the signals is compared with a reference value by an arithmetic unit and, in the case where there is a difference between the average value and the reference value, the rotational resistance is changed by activating the brake unit. Thus, a high machining accuracy can be maintained even when the sharpness of the grinding stone is reduced.

    Abstract: A method of using a finishing element and using organic lubricating films for finishing semiconductor wafers is described. The lubricants in the finishing element can be transferred to operative finishing interface forming lubricating film. The organic lubricating film thickness can be controlled to improve finishing and reduce unwanted surface defects. Differential organic lubricating film methods are described to differentially finish semiconductor wafers. Planarization and localized finishing can be improved using differential lubricating boundary layer and organic lubricating film methods of finishing.

    Abstract: A method and system for the manufacture of ophthalmic lenses comprising a computer (102) and a CNC machining platform (104) in operative connection with the computer. The CNC machining platform includes a mounting stage (110), a block (106) in releasable connection with the mounting stage, and a machining tool (112). When an unfinished lens blank (108) is properly mounted on the block, the computer is operative to direct the CNC machining platform to perform both back surface generation and patternless edging of the lens blank in one machining cycle. The computer is further operative to direct the CNC machining platform to machine a lap tool for each lens and machine a block for receiving each lens. The block is machined by the platform to include scribe lines for facilitating proper alignment of lens blank.

    Abstract: A method of conserving a facility delivered to a machine during the machine's idle mode is herein described. In one embodiment, the method is directed to a method for conserving coolant water delivery to a semiconductor wafer grinding machine. The system monitors the status of the grinder to determine whether the grinder is active or idle. After the system determines the grinder has entered idle mode, the system reduces the flow of water to the machine. In one embodiment, the flow is simply reduced while, in another embodiment, the flow is terminated. A delay circuit in the system may delay the reduction of the flow rate until some point after entering idle mode. Periodically throughout the idle mode, the system increases the flow of coolant water to the grinder to ensure the temperature of all grinder components remains consistent. The duty cycle of the coolant flow may be adjusted to optimize water conservation and machine readiness.

    Abstract: A method and apparatus for controlling a polishing characteristic of a polishing pad used in planarization of a substrate. The method preferably includes controlling the temperature of a planarizing surface of the polishing pad so that waste matter accumulations on the planarizing surface soften and/or become more soluble, and/or material comprising the planarizing surface attains approximately its glass transition temperature. The waste matter accumulations and/or a portion of the planarizing surface are in this way softened and more easily removed. The planarizing surface is either heated directly by directing a flow of heated planarizing liquid or heated air to the planarizing surface or indirectly by heating a support surface beneath the polishing pad or by heating the air proximate to the polishing pad.

    Abstract: A substrate processing apparatus is used for removing surface irregularities occurring on the peripheral portion (a bevel portion, an edge portion, and a notch) of a substrate such as a semiconductor wafer and films deposited as a contaminant on the peripheral portion of such a substrate. The substrate processing apparatus includes an edge-portion polisher for pressing a polishing tape against an edge portion of a substrate and making a relative movement between the polishing tape and the substrate to polish the edge portion of the substrate, and a bevel-portion polisher for pressing a polishing tape against a bevel portion of the substrate and making a relative movement between the polishing tape and the substrate to polish the bevel portion of the substrate.
