nikon metrology MMDx car inspection Modelmaker MMDx100Accurate non-contact measuring technology

The digital camera technology offers a measuring accuracy down to 7 microns and benefits from a true non-interpolated resolution of more than a thousand points per stripe, allowing freeform surfaces and features to be scanned accurately and efficiently.


Best-in-class productivity

Featuring high frame rates and laser stripes up to 200 mm, the digital MMDx range provides the ultimate in scanning productivity. The scanner’s digital cameras benefit from a true (non-interpolated) resolution of over 1.000 points per stripe, providing optimum resolution for scanning freeform surfaces and features efficiently.


Ideal for measuring soft and fragile parts

Tactile measuring of soft and fragile parts potentially yields inaccurate measurements or can cause surface marks. As laser scanning technology is entirely non-contact, there is no risk for damage or inaccurate measurement.

Easy part-to-CAD inspection and reverse engineering

Part-to-CAD inspection compares the acquired point cloud with nominal CAD data, resulting in easy-to-interpret geometric deviation displays. Freeform surface inspection is ideal for studying material springback and shrinkage phenomena to ensure that the shape of the part is within geometry specifications. Focus extracts geometric features highly accurately, thanks to the thousands of measurement points captured by the scanner. This multitude of points allows the software to apply very accurate line fitting to determine the exact position and orientation of a wide range of features.

Reverse Engineering quickly creates CAD surface models from individual point clouds using a straightforward workflow. Reverse engineering is typically applied when original CAD data is missing, to create CAD from handmade clay models, to update designs, or as input for rapid prototyping of freeform parts and products. For reverse engineering applications users can select from a broad offering of 3rd party packages which tightly integrate all Nikon Metrology handheld scanners.


Enhanced Scanning Performance reaches a 3rd generation (ESP3)

ESP3 incorporates dynamic point-by-point adaptation of the laser intensity. This capability allows different surface materials, finishes and transitions between various materials to be scanned without user interaction, eliminating manual parameter tuning and part spraying altogether. ESP3 is a key differentiator when scanning similar parts in different manufacturing stages; initially dealing with bare sheet metal parts and finally scanning finished products finished in any color.

Ideal for measuring soft and fragile parts

Measuring soft and fragile parts with tactile methods potentially induces inaccurate measurements or can mark the surface. As laser scanning technology is entirely non-contact, there is no risk of damage or inaccurate measurement due to part indentation.


Scanning and application software

Focus supports intuitive inspection using an articulated arm or Optical CMM with tactile and/or scanning probes. The software is specifically designed to easily control data flows with minimum user interaction. Customers can complete handheld data acquisition and inspection jobs from within Focus without compromising performance.

Alternatively, through the Nikon Metrology API, the ModelMaker handheld scanners and MCAx arms or Optical CMM can be used directly in many 3rd  party inspection software applications, including PolyWorks® and Geomagic®. For reverse engineering applications users can select from a broad offering of  3rd  party packages which tightly integrate with all Nikon Metrology handheld scanners.

Laser scanning system accuracy: the laser scanning system accuracy indicates the performance of the laser scanner combined with a handheld localizer. The test is performed by scanning a highly accurate reference plate in 5 different orientations of the articulated arm and laser scanner. The 5 resulting  point clouds are merged together into one  point cloud and a best-fit plane is constructed through this point cloud. For each of the points in this  point cloud, the distance is calculated to the best-fit plane. The result of the test is the 2 sigma value of all of the calculated deviations.
