Flexible probing options

Customers can choose between high-accuracy, no-compromise ModelMaker MMDx scanners with 50mm, 100mm or 200mm  stripe widths.

For tactile measurements, MCAx supports a wide variety of tactile (straight and hook) and touch-trigger probes in many lengths and stylus configurations.

Intuitive scanning and inspection software

Focus supports intuitive scanning and inspection using an articulated arm or Optical CMM with tactile and/or scanning probes. The software is specifically designed to control data flows with minimum user interaction.

The point cloud builds up in real-time as it is being acquired and is seamlessly followed by inspection of the measured geometry against CAD or another scan.

The Focus inspection toolbox includes advanced analysis functionality such as detailed part-to-CAD comparison, feature extraction, gap & flush inspection and GD&T.

Alternatively, through the Nikon Metrology API, the MMDx/MMCx handheld scanners and MCAx arms 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.

1The Point Repeatability Test (or SPAT) is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average center are calculated. The result is the maximum range divided by two.

2The Volumetric Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability. The result is the maximum deviation of the measuring distance less the theoretical length.
The published value is the pass-off specification for ASME B89.4.22 Volumetric Performance and VDI/VDE 2617-9 probing form (MPEPF) & Indication for size (MPEE)
Probing specifications are relevant to both the center and offset probe ports of the MCAx arm. The specifications are achieved under stable environmental conditions with the MCAx arm mounted on a base plate or magnetic base and using 15 mm diameter, 50 mm long, steel ball probes connected to both probe ports.

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 in 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 2ơ value of all of the calculated deviations.
