OMCAT can measure any component with a convex cross-section. The measurement object is rotated on a rotary stage while the measurement sensor is moved to defined measurement levels by means of a linear stage. The measured data is automatically compared with nominal contours which are saved in measurement recipes.
The measured contour is automatically aligned with the nominal contour, eliminating time-consuming alignment of measurement objects before measurement. The measurement object is simply placed on the precision rotary stage and the measurement process is started directly.
Different measurement levels and diameters can be measured across the entire detection range without the need for manual settings to be made to the sensor or for the subsequent re-calibration that this would involve.
Fast stages for positioning measurement object and sensor, a powerful internal evaluation and control processor and an additional real-time processor allow fast, fluent processing because processes run in parallel.A measurement with three measurement levels and a speed of rotation of 360°/s takes less than 7 seconds from the start of the measurement until the results have been saved.
The high sampling rate of the triangulation sensor (50 kHz) makes it possible to adjust the power of the laser dynamically and to measure on a wide range of surfaces, including dark ceramics and shiny metals. Even measurement objects with surface variations caused by welded joints, for example, can be measured precisely without outliers.
Fast, high-accuracy positioning and the direct response characteristic of the stepper motors are key features of the stages. The rotary stage with direct coupling guarantees precise positioning even with heavy measurement objects. Thanks to the integrated rotor position detection sensor, additional position encoders, which would require adjustment and maintenance, are superfluous. In combination with the lifetime lubrication, this makes the stages maintenance-free.
Several internal sensors and multi-level, decentralized temperature compensation guarantee that precise measurement results are delivered consistently, even when the ambient temperature varies.
