NDI’s PRO CMM delivers accurate, reliable 3D measurements using a high-speed Optical Tracker, flexible Multi-Sided Probe and powerful Dynamic Part Referencing. With high-accuracy (up to 20µm) over a large measurement volume (up to 35m3), the PRO CMM is the ideal optical CMM for portable measurement anywhere on the shop floor.


PRO CMM Optical Tracker

At the core of the PRO CMM system is a real-time Optical Tracker using the principles of modern high-speed photogrammetry. The PRO CMM can measure parts up to 7.5m in a single setup with micron-level accuracy throughout the measurement volume. This optical CMM is designed specifically to deliver accurate, reliable dimensional metrology anywhere on your shop floor. It has no moving parts, making the PRO CMM a reliable and proven optical CMM, even outside the stable environment of a controlled quality lab.


dpr Dynamic Part Referencing (DPR)

The ability to automatically reference and re-reference the measurement system into part coordinates is unique to optical tracking technology. With DPR, an operator can simultaneously move the part, fixture, probe or scanner, even the Optical Tracker itself, and the system will maintain accurate alignment. Unwanted motion is continuously measured and subtracted, without operator intervention. DPR can also fully automate the registration process when new parts or fixtures are presented to the inspection cell.


Multi-Sided Probe (MSP)

Each Multi-Sided Probe is factory characterized to ensure accurate measurement regardless of probe orientation. When attached to a pre-calibrated Renishaw tip, you can easily probe visible or hidden features anywhere within the PRO CMM measurement volume. Optionally, you can attach the MSP to a separately supplied scanner (see ScanTRAK II option) or mount it as a rigid body for 6DOF tracking (see PRO CMM with DMM option).
