3D measurement of multiple cutting edges with EdgeMasterX

3D measurement of multiple cutting edges


The EdgeMasterX originates from the Alicona product line for optical, automatic tool measurement in high resolution. It is a fully automated cutting edge measurement system for quality assurance of drills, millers and other round tools to be applied in production. Specifically, the EdgeMasterX enables 3D measurement of multiple cutting edges. When utilized in combination with a motorized rotation unit, users benefit from the measurement of multiple tool edges, even chamfered edges, in one single measurement run. Deviations from a CAD file or reference geometry are indicated through a traffic light system. Measurements are initiated by a single button solution allowing for measurements to be performed without any further user interaction.

High measuring point density

Up to 500 million measurement points ensure a meticulously detailed measurement with tolerances in the μm and sub-μm range along with large working distance. The high measurement point density of Focus-Variation enables operators to gain a consistently high lateral and vertical resolution across high measurement volumes.

Measurement of steep flanks

Light coming from different directions is used to positively influence a measurement. The measurement of the maximum flank angle is not restricted by the numerical aperture of an objective. Depending on the surface users measure surfaces with slope angles up to 87°.

Full form measurement with Real3D

Using Real3D, users measure surfaces from numerous perspectives. Single measurements are automatically merged into a full 3D dataset. High-precision and calibrated rotation and tilt axes ensure automated, repeatable and traceable measurement on the whole measurement object.

Focus-Variation Technology

Alicona measurement systems are based on the technology of Focus-Variation and combine the functionalities of a surface roughness measurement device and a form measurement system. Each Alicona measurement instrument is a surface measurement device, surface roughness measurement system, 3D measurement system for geometrical tolerancing and micro coordinate measurement system. The Focus-Variation technology combines the small depth of focus of an optical system with vertical scanning to provide topographical and color information from the variation of focus. The main component of the system is a precision optics containing various lens systems that can be equipped with different objectives, allowing measurements with different resolution.
