Nikon Metrology, which 20 years ago pioneered non-contact laser scanning on a coordinate measuring machine (CMM), has introduced the new Nikon InSight L100 scanner featuring superior optics and innovative camera technology. Suitable for measurement of both surfaces and features, even on shiny or multi-material parts, the equipment quickly delivers accurate data and intuitive part-to-CAD comparison reports.
InSight L100 offers speed, accuracy and ease-of-use on a CMM and is ideal for high-accuracy inspection of larger components where productivity is key. The 100mm wide field of view (FOV) combined with data acquisition speed of 200,000 points per second results in measurement productivity that until now was not achievable on a scanning CMM. To facilitate manual scan path programming, a new FOV projector ensures good part coverage.
The machine is equipped with a high quality glass Nikon lens optimised for laser scanning. Combined with the high definition camera, it results in a point resolution of 42 microns, enabling the capture of fine detail and measurement of sharp edges. The InSight L100 has a small probing error of 6.5 microns, which is a measure of the scanner’s low noise level, resulting in smooth meshes with high levels of detail. Combined with the high point resolution, feature measurement accuracy approaches that of a touch probe.
A greater range and mix of surface materials, finishes, colours and transitions can be measured more efficiently without user interaction for manual tuning or treatment of the component surface. Nikon Metrology’s fourth-generation Enhanced Scanner Performance (ESP4) technology adapts the laser intensity to varying colours or materials for each point in the scan line faster than ever.
The patent-pending, integrated mount rotation allows the scanner to rotate around its autojoint axis in 30-degree increments up to 90 degrees. This saves the use of autojoint adaptors and is particularly well adapted to measuring turbine blades or parts with vertically orientated features and edges. The InSight L100 also allows the use of an extended 105-degree PH10 A-angle, allowing better access to measure beneath or behind parts.
Laser scanning allows manufacturers to gain full insight into the dimensional quality of their products without compromising on cycle times. As the entire part is checked to the CAD model, any areas of concern are immediately highlighted by colour mapping. Further investigation and analysis is possible using fly-outs, sections and a GD&T (geometric dimensioning and tolerancing) library. The easy-to-interpret graphical reports facilitate exchange of results with internal or external colleagues and suppliers, leading to easier decision-making, faster corrective actions and shorter time-to-market.
The InSight L100 scanner can be combined with tactile probes and a change rack to create a versatile, automated multi-sensor CMM. Depending on the application, both technologies can be used independently or together within the same inspection program. The scanner can be fitted to Nikon Metrology’s extensive range of CMMs and to many other makes as well.
