Real3D How to measure undercuts In combination with Real3D, users measure surfaces from numerous perspectives. Components are measured in 3D from various perspectives and then automatically merged into a full 3D dataset. High-precision and calibrated rotation and tilt axes ensure automated, repeatable and traceable measurement of form and roughness on the whole measurement object. Users are able to visualize and measure surface features such as diverse flank angles, thread pitch and undercuts. Alicona offers several options for Real3D measurements. The Advanced Real3D Rotation Unit is equipped with a motorized tilt axis and motorized rotation axes, whereas the Real3D Rotation Unit is based on motorized rotation axes and a manual tilt axis. Both models are used for full form measurement of typically round tools. The fully motorized version can additionally be applied for the automatic measurement of cutting dies, micro hole measurement and Reverse Engineering. Further, users are able to measure trail and main edges of their drill, cutting miller etc. in only one measurement circle. The compatibility of both units with a number of clamping systems allows for precise and rapid interaction between processing and measurement. In addition, various adapters enable 360° rotation and components without rotational symmetry.
