Electronic Measuring Devices (EMD) Legend Integrated Metrology Center

Electronic Measuring Devices (EMD) Legend Integrated Metrology CenterThe EMD Legend Integrated Metrology Center is a precision coordinate measuring machine (CMM) that is available for user research projects. The Legend incorporates multiple measurement sensors and is ideal for measuring small components with high accuracy. The Sceptre software, an extremely flexible BASIC-like programming language, is used to control machine motion and to perform sophisticated data analysis routines. Measurement results can also be exported to CAD/CAM systems for further analysis.





Metals and Ceramics Division

Measuring volume

The CMM worktable has a 300 x 300 x 300 mm (1 cubic foot) usable range, but can accommodate larger parts

Measurement uncertainty

Approximately 2.5 micron (0.0001 inch) measurement uncertainty over the entire working volume in linear, single-point mode

Measurement repeatability

Better than 1.0 micron (0.00004 inch) in linear, single-point mode

Analog sensor

Constant-force, contact sensor is designed to operate in both single-point and continuous-path scanning modes

Video camera sensor

For measuring 2D features such as holes and slots, where the depth measurement is not critical
