An accuracy analysis system for a machine tool includes: a control unit, a data server, a data communication unit, a data analyzer, a corrected machine accuracy calculation unit, and a data display unit. The control unit stores preliminarily obtained accuracy data regarding a machine accuracy, compensation data for compensating for an error, and machine information. The data communication unit transmits the accuracy data, the compensation data, and the machine information to the data server. The data analyzer uses the accuracy data and the compensation data in the data server to obtain a compensation data correction value as a correction value of the compensation data and expected accuracy data when the compensation data correction value is applied. The corrected machine accuracy calculation unit calculates a post-correction machine accuracy from the expected accuracy data. The data display unit displays the post-correction machine accuracy calculated by the corrected machine accuracy calculation unit.

A locating fixture that includes a base, an adjustable locating member, a plurality of indicia, a restraining member and a lower substructure. The base includes a raised platform having a mounting aperture. The adjustable locating member is disposed within the mounting aperture and includes a part locating feature and a position indicator fixedly attached to the adjustable locating member. The plurality of indicia is located on the raised platform adjacent to the adjustable locating member. The position indicator cooperates with the plurality of indicia to determine a vertical position of the adjustable locating member. The restraining member is cooperatively engaged with the adjustable locating member. The lower substructure is configured to allow for longitudinal and lateral translation of the base. The base is translatably mounted to the lower substructure.

A method for measuring a rotation center of a multi-axis processing machine 100 includes: using reference ball 8 and a measurement device 7 which has a probe 71 and measures, as a measurement value 72, a movement amount of the probe 71 when the reference ball 8 contacts the probe 71; executing a measurement process of rotating the rotation axis to measure the measurement value 72 in a state in which the reference ball 8 installed to one of the processing head 2 and the table 62, 63 contacts the probe 71 of the measurement device 71 installed to another of the processing head 2 and the table 62, 63; and executing a rotation center calculation process of calculating a rotation center of the rotation axis from the measurement value 72, a rotation angle of the rotation axis, and a position of a center of the reference ball 8.

A dental milling machine (100) for manufacturing a dental object (101), having a microphone (103) for detecting sound signals during a milling operation or an accelerometer for detecting vibration signals; and a position determining device (105) for determining a position of a milling tool (107) and/or a workpiece (111) based on the sound signals or the vibration signals.

A set-up gauge for precision alignment of the cutting knives in a cutter head. The set-up gauge utilizes a support bar extending laterally across the wood shaper. Also included is a bracket slidably secured to the support bar and a rod extending outwardly from the bracket, the rod further comprising first end and second ends. Further included is a magnetic disc secured to the second end of the rod, the magnetic disc for contact with a surface of the cutting knives to identify a common inset distance for each of the cutting knives relative to the guide fence.

Power tool methods and systems are provided for aligning a power tool to implement an angled cut in a workpiece. The power tool includes a first distance sensor and a second distance sensor. The power tool measures a first distance to the workpiece with the first distance sensor and a second distance to the workpiece with the second distance sensor. The power tool calculates an angle between the power tool and the workpiece based on the first and second distances, and indicates the angle via an angle output indicator of the power tool. The power tool may measure an angle between the power tool and the workpiece using a proximate edge and a distal edge of the workpiece, and indicate whether the power tool maintains a correct angle as it traverses a cut through the workpiece from the proximate edge to the distal edge.
