ICYMI – Watch the latest Nikon Metrology webinar here. The Nikon CMM Laser Scanners – PolyWorks compatible webinar with AMS focuses on the benefits that Nikon laser scanners, coupled with PolyWorks can bring to various industries and diverse applications.
With 3D laser scanning now well established within automotive inspection applications, the challenge for OEMs and suppliers is to reduce costs and deliver high quality products. Universal metrology software for CMMs, portable arms or handheld devices furthers this desire from product engineering to production.

Laser scanning provides highly effective inspection
Whatever the product, be it a car, hand drill or mobile phone, customers expect its tightly-toleranced parts to fit together and function perfectly and at the same time be of high quality and attractive design. But how do manufacturers ensure this level of precision without delaying the development and launch of the product?
The answer is to digitise the 3D shape and features of the prototypes with a non-contact laser scanner mounted on a coordinate measuring machine (CMM) or articulated arm and compare the results to the original CAD designs. It is much faster to inspect a part this way than to use a touch probe to take discrete measurements. With tens of thousands of points per second being captured by the laser and added to the point cloud, a complete inspection cycle is often between five and 10 times faster than tactile probing.
Furthermore, with the latter technique it is impossible to know what is happening between two adjacent discrete points, so the data is very sensitive to imperfections in the geometry being inspected. Parts that have flatness and roundness errors, edge rollover or burrs are particularly problematic. Radius compensation error is a further difficulty with tactile probing. When a stylus makes contact with the edges of a hole, for example, radius compensation may result in unexpected measurement points if a neighbouring surface is touched first.
