A measuring arm is a mobile coordinate measuring machine that offers great flexibility thanks to its many degrees of freedom and compact size. Using a portable measuring arm, our engineers can capture the complete geometry of a component. Unlike a coordinate measuring machine, a measuring arm does not have linear sensors. The combination of fixed lengths with high-resolution incremental angle encoders makes it possible to reach any point within the measurement volume from various scanning directions. sigma3D relies on FARO measuring arms for this technology.
Measuring Volume:
The measurement volume of the measuring arm is limited to the respective length of the arm. Depending on the measurement application, sigma3D uses measuring arms with lengths ranging from 1.8 m to 3.6 m. Through specialized measurement methods and in combination with a laser tracker, the measurement volume can be expanded as needed.
Measurement Accuracy:
The measurement accuracy of the measuring arm depends on the length of the arm. The range of maximum volumetric deviation extends from 0.034 mm to 0.091 mm.
Software:
For the tactile measurement of components or fixtures, we use various software packages depending on the measurement task. sigma3D relies on the software packages Polyworks, Spatial Analyzer, Metrolog, and MeasureX.
Data Exchange:
Data can be exchanged via email, FTP server, or directly in person on-site. Alternatively, data can of course also be sent by mail on a CD.
