The latest automobiles with diesel engines have performance, excellent fuel efficiency, and low emissions. With electronic data management of the engine to optimize the combustion several critical parts require a manufacturing process to achieve a tolerance better than 2 microns.

The measuring gauges for these processes must have a total accuracy of some nanometers. This precision has already been reached in the metrology laboratory with temperature stability, but it is unusual to be applied to machine tools on the shop floor. A use of this special gauge is the grinding process of components for the diesel engine injection and hydraulic spools where matching tolerances are often of few microns
