This is a method of measuring three-dimensionally using a coordinate measuring machine, and is capable of measuring the dimensions, positioning, contour shape, and geometric tolerance of an object with high accuracy. AeroEdge incorporates two types of coordinate measuring machines into its mass production line: a high-speed CMM for on-site use and a 5-axis optical coordinate measuring machine (non-contact type) that uses a white light sensor to perform quality assurance immediately after machining. By using high-precision CMMs equipped with ZEISS VAST gold probes as mother machines, we are able to achieve a high level of quality assurance with dimensional measurement capabilities for mass-produced products with complex shapes.
