Optical CMM becomes dynamic measuring
machine
Metris released K-Series DMM 3.0, the software that upgrades the K-Series Optical CMM system into a "Dynamic Measuring Machine".
Metris has released K-Series DMM 3.0, the software that upgrades the K-Series Optical CMM system into a "Dynamic Measuring Machine" By tracking the 3D position of a set of infra-red LEDs attached to the test object, its relative motion and deformation are analysed

An X-Tek X-ray inspection system is testing high-complexity printed circuitry boards that feature BGAs and CSPs to speed production of highly complex electronic and mechatronic products.
Only 3 LEDs attached to an object, suffice to measure its full 6-DOF position including rotation.
By capturing 3D coordinates and 6-DOF motion at a high frequency, the DMM 3.0 software enables to measure dynamic properties like displacements, velocities, accelerations, overshoots and oscillation frequencies.
The lightweight sensors are designed to have a minimal influence on the dynamic behavior of the measured objects.
The non-contact nature of the system and the large working volume (up to 17m for a single camera) enables the measurement of large displacements and deformations, a typical limitation for classical mechanical devices like LVDT or string potentiometers.
DMM 3.0 is based on a new software platform that enables direct data streaming of coordinate data to client applications without any limits of the measurement time.
This sensor approach allows an easy integration of the K-Series DMM displacement sensor into any measurement or control platform.
A 3D scene viewer continuously visualizes the measurement environment while measuring.
Furthermore DMM 3.0 supports the use of up to 8 cameras as such extending the measurement volume to the needs of the user.
The user friendly DMM 3.0 is compatible with the post-processing and visualization functions of the DMM Modular 2.5 analysis software.
K-Series DMM targets a variety of applications where the key requirements are to accurately measure and track grids of points or multiple objects in space.
Examples are wheel and body motion on dynamic test benches, tracking and adaptive control of industrial robots and (hydraulic) actuators, opening and closing of interior/exterior parts of cars and airplanes (door, trunk lid, convertible roof, dashboard, etc.).
It is also applicable for structural testing on large structures like wings, landing gears, concrete girders and buildings in earthquake research. Request a free brochure from Metris ...
