Multi-Sensor CMM Eases Micro-Measuring

摘要

Machining on a micro scale is challenging enough, but very small parts also create special metrology challenges. The relatively large size of most traditional CMMs makes it challenging to accurately measure the geometry of such components, which often require smaller sensors and a higher degree of precision than larger parts. To meet increasing demand in the medical, electronics, aerospace and other industries, Carl Zeiss (Maple Grove, Minnesota) offers a CMM designed specifically to meet stringent quality assurance standards for small, intricate work-pieces. According to the company, the F25's precise kinematics and high accuracy enable measuring uncertainty of 250 nanometers at a resolution of 2.5 nanometers.
