摘要:
The invention relates to an articulated arm CMM (1), which is constructed in a modular way, and a modular assembling kit for constructing such an articulated arm CMM (1) comprising an articulated arm (2) having a first end (22) and a second end (24), wherein the second end (24) is configured to support a tool(66). The articulated arm (2) comprises at least two arm sections (68, 68', 68"), connected to one another by pivot joints (70, 70', 70") with integrated angle encoders (40). The arm sections (68, 68', 68") are configured as modules (69, 69', 69") having a PCB unit (10, 12), said PCB unit (10, 12) comprises an elongated PCB section element (14) and at least one PCB encoder element (16a, 16b). The PCB encoder elements (16a, 16b) are configured to build an angle encoder (40) and the PCB section elements (14) comprise electronic transmission means (28) for transmitting the encoder signals from the PCB encoder elements (16) toward a circuit deriving the relative position between the arm sections.

摘要:
Calibration method for a coordinate measuring machine (1), the coordinate measuring machine (1) comprising a drive mechanism for moving a tool carrier (15) relative to a base (11) for approaching a measurement point and comprising a calibration laser head (20) implemented so and attached to the tool carrier (15) so that a laser beam (25), which is emittable by the calibration laser head (20,21), is swivelable around at least two basically perpendicular axes (X,Y,Z) and changes in distance are measurable interferometrically by means of the calibration laser head (20). A set of retro-reflectors (16a-d) is arranged in fixed positions relative to and/or onto the base (11). The method comprises emitting and directing the laser beam (25) towards a first of the set of retro-reflectors (16a-d), whereby a measuring path (26) is defined by the orientation of the laser beam (25), moving the calibration laser head (20) along the measuring path (26) so that the laser beam (25) is kept directed towards the first retro-reflector (16a) according to the measuring path (26) and the reflected laser beam is continuously received at the calibration laser head (20), measuring the change in distance to the first retro-reflector (16a) at a plurality of measuring positions along the measuring path (26) and gathering a machine position for each of the plurality of measuring positions, the machine position relating to a position of the tool carrier (15) relative to the base (11).
摘要:
The invention relates to a handheld measurement instrument (10) and a configurator (80) forming a measurement kit. The measuring instrument (10) and the configurator (80) are provided each with an interface (30, 35, 36, 84, 86, 87), enabling communication between the measuring instrument (10) and the configurator (80). The handheld measurement instrument (10) further comprises a measuring unit (21, 21a, 21b) for measuring distances or angles of an object by contacting physically distinct points of said object; and a circuit unit (50) applying a function of a functionality on electronic signals/electronic measurement results delivered from the measuring unit (21, 21a, 21b) in order to deliver the measuring results in a desired form to the user by output means (28). The form the results should be presented can be selected by the user using input means (26) of the measuring instrument (10). The circuit unit (50) is configurable by the user using the configurator (80) in order to determine, with which functionality the circuit unit (50) and the input means (26), respectively should be equipped.
