MCAx - Premium portable metrology


Tags : Nikon 

The MCAx Manual Coordinate measuring Arm is a precise, reliable and easy-to-use portable 7-axis measuring arm. It is the perfect partner for the ModelMaker handheld laser scanners and Focus Handheld scanning and inspection software. This total solution’s accuracy, capability and portability make it feel perfectly at home in the metrology lab, on the shop floor and in-the-field.

The arm can be equipped with a wide range of probing systems aside from laser scanning, such as a large choice of probes for a variety of tasks including touch-trigger measurements and continuous scanning. Its flexibility makes this measurement arm the perfect solution for the widest range of measurement tasks. The MCAx range of 7-axis articulated arms is available in six different sizes and in three accuracy levels giving users the ability to specify the best system for their needs.

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 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.
