Millionths of an inch (0.025 micron) measurement requires special methods and equipment. This paper will discuss considerations and practices we have found effective for maximizing accuracy in microinch measurement. Topics covered will include temperature, contamination, penetration, alignment, vibration, wear, looseness, the operator, and equipment.

New Data – Stress Concentration Factors for optimised holes in flat plates
ESDU 15005 considers the optimisation of the shape of typical holes found in structural components to significantly reduce the peak elastic stresses around the hole, as well as to increase the fatigue life of the component under a given set of loading and geometry conditions. Finite element ana... Read more...More Product Announcements from IHS ESDU
