MEASUREMENT & INSPECTION


Workaday Metrology


This on-machine scanning analog probe from Renishaw, the SP60, collects up to 1000 points/second—useful for nonprismatic shapes often used in critical applications like turbine blades.


Metrology suppliers continue to fi nd innovative ways to bring high-tech measuring devices, including dedicated gages, closer to the production line

T


he trend to place more accurate metrology devices on the shop fl oor continues. One rea- son is the evolution of the metrology devices themselves. They are getting faster, more


rugged, and smaller. Matching the means is motiva- tion. Manufacturers want to understand quickly what is happening in production, rather than wait for results of parts transported to a quality lab. Competitive pres- sures have manufacturers asking for more data, faster. One way for metrology suppliers to easily help in


this regard is to fi nd new shop-fl oor uses for estab- lished applications. For example, engineers at Nikon Metrology (Brighton, MI) came up with the idea of applying their MV330 or MV350 laser radars to in- process monitoring of automotive body-in-white (BIW) assembly. The MV330/350 uses a focused laser con- trolled by high-precision azimuth and elevation drives, commonly used in airframe assembly. While aircraft
