If the IQR falls below the IQR threshold, surface normal angle errors (SNAE) may be calculated and plotted to the surface model. If the SNAE plot does not include closed contour regions, the socket may proceed to patient fitting. If the MRE or IQR thresholds are exceeded, or if the SNAE plot indicates closed contour regions, the socket may be reshaped accordingly, prior to fitting.

  • Patent number: 9002502
    Abstract: The present invention provides a method and the like that are capable of calculating a correction value for a rotational axis and make it possible to correct an error in position or position and posture of a tool, which results from a geometric error, correct an error in posture of the tool, and also enhance the accuracy in machining by preventing a translational axis from operating in an infinitesimal manner due to a correction command. In a machine tool having two or more translational axes and one or more rotational axes, a correction value for each of the translational axes is calculated using a command position of each of the rotational axes, a coordinate value of a correction reference point as one point designated in advance in a command position space of each of the translational axes, and a geometric parameter representing the geometrical error.

  • Patent number: 8996156
    Abstract: A method and system for automated repair of a machine component is provided. According to the proposed method, a first geometry of the component, including a damaged portion of the component, is digitalized. A trough is then machined over the damaged portion of the component. The machining is numerically controlled using digitalized geometrical data of the first geometry of the component. A second geometry of the component is then digitalized subsequent to the machining, the second geometry including the trough. Subsequently, a material is deposited over the trough. The deposition of the material is numerically controlled digitalized geometrical data of the second geometry of the component.

  • Patent number: 8988033
    Abstract: A machine tool includes a main axis 30 to which a touch probe 17 is attached, a motor 15 that rotationally drives the main axis 30, a rotation angle position detector 16 that detects a rotation angle position of the motor 15, and a control device 20. The control device, when a measurement mode command for performing measurement of a workpiece by the touch probe 17 is input, multiplies a d-axis current command value Idc by a d-axis current correction coefficient K that is less than 1 to reduce the d-axis current command value Idc to a d-axis current command correction value Idc?, using a d-axis current command correction section 4. Thus, in the machine tool, small rotation vibrations of the main axis, generated when rotating the main axis to which the probe is attached and performing measurements of a workpiece, can be suppressed to thereby increase the measurement accuracy.

  • Publication number: 20150045940
    Abstract: A servo control device (20) includes a position feedback unit (21) that performs position feedback control for matching the position of a driven unit to the position command for each of X, Y, and Z axes and a speed feed forward unit (22) that performs speed feed forward control, which is for compensating a delay in the position control for the driven unit due to position feedback control, for each axis. The servo control device (20) changes the position loop gain for each axis to the same value set in advance when the speed feed forward control is OFF, and changes the position loop gain based on the position feedback control to the optimal gain corresponding to each axis when the speed feed forward control of the speed feed forward unit (22) is ON.
