    摘要: A method of evaluating an accuracy in which an operating accuracy of a machine can be easily evaluated on the side of a numerically controlled system without using a special measuring device. For example, during execution of a circular arc processing program (14a) for evaluating an accuracy by the processor (11) of a numerically controlled system (10) with numerically controlled machine (30) idly operated, machine operating positions in directions of an X-axis and a Y-axis are periodically measured in response to position feedback signals output from pulse coders provided on servo motors of the X-axis and the Y-axis of a machine tool, and stored in a memory (13). Upon completion of the execution of the program, a radius of an operating path and an error with respect to a specified radius on the X-Y plane of the machine tool are calculated by the processor based on the measured positions in the directions of the X-axis and the Y-axis. The machine operating path is displayed on the display unit (16a) together with the specified path and allowable external and internal paths for the accuracy evaluation by the operator in accordance with image signals produced by a graphic control circuit (16) based on the calculated path or the calculated radius error, the radius specified by the program and allowable upper and lower limit radii.

    摘要: A calibration device (30) for a machine tool is described that includes a base (36) attachable to a machine tool and a calibration artefact (32), such as a sphere of known radius. A deflection mechanism attaches the calibration artefact to the base and allows movement of the calibration artefact (32) relative to the base (36) when an external force is applied to the calibration artefact (32). The deflection mechanism also maintains the calibration artefact (32) in a defined rest position relative to the base (36) in the absence of an applied external force. A sensor (46) is provided for sensing the extent of movement of the calibration artefact (32) relative to the base (36). A method of using the device (30) with a reference tool to accurately determine a position of a calibration artefact (32) is also described.

    摘要: A system and a process are disclosed, that are automated and integrated with numerically controlled systems, for measuring compensating and testing numerically controlled machine tool heads (1) and/or tables. The system comprises: at least one support base (11) equipped with a plurality of distance sensors (14); at least one device (16) of the gage tool type composed of an elongated cylinder (17) that is equipped at one of its ends with connection means (18) for the heads (1) and is equipped at another opposite end with a ball (20), wherein the ball (20) is placed next to the sensors (14) so that they are able, always and in any position, to measure the distance that separates them from the ball (20) and determine thereby the position in the Cartesian space.
