Machine Tool Metrology
Machine tool metrology is the process of verifying machine tool performance, calibration, and accuracy. Maintaining machining tools such as lathes, mills, grinders, and laps ensures the quality of the components being manufactured as well as reducing the number of parts that may need to be scrapped or reworked. Feedback from these measurements can also be used to guide process control systems.
About Surface Metrology
Surface metrology is important because a surface’s topography, or surface texture, determines its physical and mechanical properties. These properties include: friction, adhesion, oxidation, and thermal and electrical conductivity.
Surface metrology can be used to control many functions on manufactured objects and mechanical components, such as: Reducing wear on moving parts, Increasing the lifespan of moving parts, Ensuring sealing between shafts and seals, Decreasing fuel consumption, and Optimizing the efficiency of solar cells.
Surface metrology can be measured using contact or non-contact methods. Contact methods use a measurement stylus that’s dragged across the surface, while non-contact methods include interferometry, digital holography, and confocal microscopy.
