摘要： A cassette type part clamping member holding precision parts of small size to very close tolerances. The parts are clamped in a manner so that they are securely held but are not damaged. The cassette mounts relatively easily made, low cost, and useful reference bar for providing a reference surface against which the parts are clamped and also against which a sensor will operate during an operation such as grinding to insure that a straight grind cut is made. The cassette that holds the part clamping members and the reference bar, and a separate outer cassette holder fixture which provides reference surfaces for supporting the reference bar holding it in position accurately and without affecting the preload on the clamping members is mounted on the tool table. The cassette can be removed from and replaced into the holding fixture without releasing the parts.
摘要翻译：一种盒式部件夹紧部件，其保持精密部件的小尺寸至非常接近的公差。这些部件被夹紧，使得它们牢固地保持而不被损坏。盒子安装相对容易制造的，低成本的和有用的参考杆，用于提供部件被夹紧的参考表面，并且传感器在诸如研磨的操作期间将被操作以确保进行直线研磨切割。保持部件夹紧构件和参考杆的盒子以及单独的外部盒式固定器夹具，其提供用于支撑参考杆的参考表面，用于将参考杆保持在准确的位置并且不影响夹紧构件上的预载荷。盒子可以从保持夹具中取出并替换，而不会释放零件。

摘要： A control system for precision machine tools and similar devices provides a precise position during active operations on a table supported workpiece or part. The present system provides a support table on which a machine part or specimen is mounted that is controlled in its position through a friction free spring type hinge relative to a base, and which is held therein with a piezoelectric actuator operated in an active closed loop system to maintain a set position without any backlash.
摘要翻译：用于精密机床和类似装置的控制系统在对工作台或部件的活动操作期间提供精确的位置。本系统提供了一种支撑台，机架部件或样本安装在该支撑台上，该台面部件或样本通过相对于基座的无摩擦弹簧式铰链而被控制在其位置，并且其中保持有在主动闭环系统中操作的压电致动器保持固定位置，没有任何反弹。

摘要： A table for use with CNC machines has section one table feature being mounted for movement on the base and the other table section being mounted on the one table section. The table means are movable along mutually perpendicular axes, and are controlled in the axes. Motion error is compensated by providing feedback signals that sense and feed back position signals in one controlled axis as the table sections are moved in the other perpendicular axis. Compensation for deviations in motion in the mutually perpendicular axis is provided so that position in each direction of motion is controlled by two feedback signals for error compensation.
摘要翻译：与CNC机床一起使用的工作台具有安装在基座上的第一表面特征，另一个工作台部分安装在一个工作台部分。工作台装置可沿着相互垂直的轴线移动，并被控制在轴上。通过提供反馈信号来补偿运动误差，当反馈信号在另一个垂直轴上移动时，通过反馈信号来检测和反馈位于一个受控轴上的位置信号。提供在相互垂直轴线上的运动偏差的补偿，使得每个运动方向上的位置由两个用于误差补偿的反馈信号控制。
