摘要： A present invention is for a device and method for measuring and calibrating the rotary motion of a rotatable machine member, such as a pivotable swivel member (2b) of a spindle (2) of a five-axis machine tool (1). The device includes an arm (110) mounted to the spindle, a housing (120) mounted to the arm, an optical encoder mounted internal to the arm and positioned therein to measure rotation about an axis extending lengthwise along the housing, which such axis is parallel to the axis about which the swivel member rotates. The device also includes a rotary table (170) mounted to the housing opposite the arm, the rotary table comprising a stator (171) fixedly mounted to the housing and a rotor (172) clampedly affixed to a shaft passing through the housing. The shaft is coupled to an input shaft of the encoder such that rotary movement of the rotor can be measured by the encoder. An electronic level (190) fixedly secured to the rotor, such as by a bracket (180). The encoder, the rotary table and the level are each electronically coupled to a control system which is adapted to obtain readings from the encoder and from the level and to command controlled rotation of the rotor relative to the stator.

摘要： The invention relates to a coordinate measuring machine (CMM) for determining a measuring position of a probe. The CMM comprises an articulated arm having first and second ends and at least one joint between the first and the second end, the first end forming a base being positionable on a supporting surface, the second end being movable relative to the first end and having attached the probe. Further exists at least one sensing unit for measurement of an actual relative setting of said at least one joint and at least one computing unit for calculating a measuring position of the probe relative to the base, as well as for referencing the measuring position in an external coordinate system by using a provided base-position in the external coordinate system.
According to the invention, the articulated arm further comprises a first inclinometer for measurement of a slope relative to an external vector referenced in the external coordinate system, particularly relative to the gravitational vector. Connected to the measured slope, the first inclinometer provides an electronic slope value, this slope value being used - beside the provided or previously determined external base-position - for referencing the measuring position in the external coordinate system.
