    • The present invention provides a visual drag diagnostic apparatus, software and method for CNC machines. The present invention creates a visual display or plot of the drag values associated with the CNC machine's moving components along each axis of movement of a tool holder or table. The plot created by the present invention provides a diagnostic tool to evaluate the operational status of the CNC machine, which is quick to perform and easy to understand by the operator. Knowing the drag values allows an operator to foresee problems with tool holder or table movement before making a product, thereby saving time and money during machining operations.
    • 本发明提供一种用于CNC机器的视觉拖动诊断装置,软件和方法。 本发明创建与CNC机床的移动部件相关联的沿工具夹或工作台的每个运动轴线的牵引值的视觉显示或绘图。 由本发明创建的情节提供了一种用于评估CNC机器的操作状态的诊断工具,该操作状态由操作者快速执行并易于理解。 了解拖动值允许操作者在制作产品之前预见刀架或工作台移动的问题,从而在加工操作期间节省时间和金钱。

    • A control system for a door or gate which is movable between an open position and a closed position by an automated operator, comprising a door travel organizer which divides the door travel into a plurality of segments and each segment into a plurality of sectors; a sensor to sense at each sector, the resistance of the door or gate against opening and closing whilst moving between the open position and the closed position over a predetermined number of open close cycles, and to generate at least one signal representative of that resistance in each segment over the open close cycle, a recorder connected to the sensor to receive each representative signal and to store such a signal; a comparator to compare each signal with a resistance trip point set for each segment and generate a resistance profile for the door or gate over an open close cycle of the door or gate; a calculator to calculate the resistance trip point for the door or gate for each segment based upon the highest resistance encountered in any sector of that segment; and a controller to receive each trip point and set each trip point as a threshold for each segment such that if resistance of the door or gate sensed by the sensor in any sector exceeds that threshold for that interval, the movement of the door or gate is interrupted.
