    摘要: A method and an apparatus for detecting machining flaws of machine tools mechanically removing material from surfaces, especially of grinding machines, with the help of which the occurrence of machining flaws can be determined directly during the machining of the workpiece itself. This is achieved as far as the method is concerned in that the force exerted by the tool bit upon the workpiece during the machining process is measured as an “actual or momentary” value. This value is then fed to an electronic data processing unit and is compared there with a “nominal” value stored there and obtained from the processing of an unflawed workpiece, the thus obtained values can be documented and used to identify a flawed product.

    摘要: A machine tool position detection error measurement method that eliminates the effects of pitch, yaw, and roll of the axes at the point of machining of a CNC machine tool and improved machining accuracy. The method comprises a step of compensating positioning accuracy of a positioning-error-measuring linear scale using a laser distance-measuring device, a step of mounting the compensated positioning-error-measuring linear scale parallel to a linear axis of the machine tool, and a step of comparing a motion amount obtained from the position detector by moving the linear axis a certain amount and a motion amount read from the positioning-error-measuring linear scale mounted parallel to the linear axis and storing a difference therebetween as error data of the position detector for the machine tool.

    摘要: An angular velocity detected by an angular velocity sensor (10) is integrated by a small angle matrix calculator (12) and a matrix adding calculator (14), and then restored as a posture angle (angular velocity posture angle) by a matrix posture angle calculator (16). A posture matrix is calculated by a tilt angle calculator (22) and an acceleration matrix calculator (24) and an acceleration detected by an acceleration sensor (20) is restored as a posture angle (acceleration posture angle) by a matrix posture angle calculator (26). Low pass filters (18, 28) each extract a low range component, the difference between the two is calculated by a differencer (30), and only the drift amount is extracted. A subtracter (32) removes the drift amount from the angular velocity posture angle and the result is output from an output device (34). In addition, a posture angle matrix calculator (36) converts the result to a posture matrix, which it feeds back to the matrix adding calculator (14).
