Metrology is the science of measurement and these skills are vital across all major growth sectors of the global economies, enabling innovation, jobs, and industry sustainability.
The push for increased fuel efficiencies has pushed the aerospace industry to develop stronger and lighter materials while simultaneously increasing component longevity. In turn, these new designs, materials, and processes require verification.
In a previous article, we observed how multi-sensor CMMs can perform 2D and 3D measurements interchangeably in a single run. Today, high-precision CMMs also can carry out form measurement functions, says David Wick, product manager at ZEISS Industrial Metrology.
Camcraft Inc., located in Hanover Park, IL, manufactures high-precision components and assemblies. Utilizing the latest machining technology and automation, Camcraft manufactures the most complex hydraulic engine management and fuel system components for on- and off-highway applications.
When explaining surface finish measurement, it can be helpful to start with the classic metaphor of a desert, as often described by gage maker Taylor Hobson. Imagine grains of sand as roughness, the ripples of sand as waviness, and then the undulating dunes as the surface profile.
Calibration reports are supposed to be clear and concise so the reader can understand the details. In fact, the ISO 17025 standard has a section that deals with this topic in specific terms so it would seem there should be no room for misinterpretation.
