Nikon Metrology Machine

Metrology is the science of breaking down measurements. Of the activities related to this science, the coordinate-measuring machine (CMM) like the Nikon Metrology Machine is specific to the activity of traceability and sensors.

Using three axes, each one has a scale system that indicates where it is located near the object and then displays these readings in a mathematical form. Arranged orthogonal to each other, the points of the axes can be analyzed by regression algorithms to determine the construction features. The sensors allow exact product dimensions to be measured and later reproduced.

The information provided by a CMM is what machining centers use to calculate the exact dimensions of a product. Without this product specific data, machines would not build with such precision. It is the physical geometrical characteristics of an object recorded by a CMM that allows the standard of replicability of products and one reason machining centers thrive.

Methodology behind traceability is based on the idea that instruments can be redeveloped based on a calculation or set of data regardless of size. Like ratios of ingredients to prepare a given amount of one recipe, the data from CMM should be able to be skewed to replicate the part at any given size. Some examples of this apply especially to the exterior of products. Select parts of aircrafts, ships, and other large machines are often produced in multiple sizes.   When several sizes and identical models exist, precise production of identical sized parts and the ratio between parts directly impacts the function and success of the completed product.

An example of the above can be applied to the select sizes the Nikon Metrology Machine is available in. Each machine can only measure pieces that can fit with its size. Where the Nikon Metrology C3 can measure small parts, and light materials, the larger Nikon Metrology C3 V GP can work on materials such as marine and locomotive equipment.
