Are you looking to learn Optical Coordinate Measuring Machine (Optical CMM) basics, including capabilities, best practices, advantages, and next-generation functions? Our free metrology resource site offers fundamental knowledge related to dimensional measurement instruments, environment requirements, selecting the right tool for the job, and various inspection processes.
What is an Optical Coordinate Measuring Machine (Optical CMM)? Also commonly known as a vision measuring machine (VMM) or a video measuring machine. An optical CMM is a 3D measurement system with three-vertical-axis movement systems to construct a spatial coordinate system, the coordinate point cloud can be detected by the sensors with the travel working of three-axis-linear-scales. These sensors include a vision sensor such as a CCD or CMOS camera or laser probe.
Optical coordinate measuing machines (Optical CMMs) allow for three-dimensional inspection of parts. Measurements include lengths, angles, diameters, planes, cylinders, spheres and GD&T. They have the advantage of being non-contact, highly accurate, computerized for data collection, and performs complex dimensional inspections.
Learn about the core techology that drives these tools, and the next-generation optical coordinate measuring machines using the principals of these tools of in new ways to bring added-value to production and quality inspection.
