Portable CMM offers increased accuracy for 3-D measurement

Hexagon Mfg. Intelligence has introduced the 77 series portable coordinate measuring machine (PCMM), which the company says is the most accurate Romer Absolute Arm to date. It is designed for high-end 3-D measurement applications.

The machine achieves nearly a 20 percent improvement in scanning accuracy and a 15 percent improvement in touch-probe measurement accuracy over the 75 series. It is available in five sizes from 8.2- to 14.8-ft. measuring volumes.

The PCMM can be switched on and used immediately without warmup or referencing. Probe changes can be made without calibration. Acoustic and haptic operator feedback facilitates usage in harsh shop floor environments.
