TRITOP | GOM

Mobile Measuring System

The portable TRITOP CMM system measures coordinates of three-dimensional objects quickly and precisely. Measuring tasks that were traditionally performed by tactile 3D coordinate measuring machines can now be carried out easily with the TRITOP CMM system. It does not require any complex, heavy and maintenance-intensive hardware. The measuring machine comes to the object.

As with tactile coordinate measuring machines, TRITOP records the coordinates and their orientation in space for any feature of interest.

Surface points and sections
Primitives
Holes, punch holes and edges
Diameters, lengths, angles

After the 3D coordinates have been determined, the measurement is mathematically transformed into the coordinate system of the component.

RPS
Gage alignment
Best-fit

When comparing the measuring data with CAD data (IGES, VDA, STEP, Catia, ProE, UG), the corresponding measuring reports are created in the familiar formats.

False-color representation
Deviation of individual points as labels
Sections, angles and distances
Diameters and flatness
Tables and lists

The measured and aligned data is used for various tasks.

CAD comparison
Verification of shape and position tolerances
Verification of specifications from drawings, files or tables
Initial measurements

Fields of application

Inspection of sheet metal parts and car bodies, e.g. in pilot production, process optimization, tool try-outs, series production ramp-up or during random samples
Quality control of large objects, e.g. aircraft, ships, wind turbines, etc.
Verification of plastic parts, e.g. for first article inspection
Verification and recording of fixtures
Measuring of models and prototypes, e.g. vehicle interior and exterior design
Verification of tubes and wires with respect to their three-dimensional shape
Measuring trimming edges of two-dimensional sheet metal blanks
Deformation analysis of car and climate chamber tests
Measuring of reference point fields

Static Deformation Analysis

TRITOP is a mobile optical measuring system, which accurately defines the 3D coordinates of object points at quasi-static conditions. Based on this information, TRITOP is capable of calculating 3D displacements and deformations of objects and components.

The non-contact TRITOP system replaces conventional displacement measuring systems or LVDTs capturing displacements and deformations rapidly without cables or sensors on or around the object, and does therefore not interfere with the measuring object.

TRITOP provides for any number of measuring points information about:

3D coordinates
3D displacements
Deformation
Bending, torsion, deflection
Rotation angles
6 degrees of freedom (6DoF)
Relative displacement (point – point, point – line, point – plane)

These results can be presented in diagrams, directly on CAD data or superimposed onto the recorded camera images providing an intuitive result presentation that is easy to understand.

Fields of application

Climate chambers
Environmental simulation
Stiffness testing
Gap size change
Flush
Verification and optimization of simulations
Component deformation and testing
Relative motion
Global strain
Load tests and aging tests (force & temperature)
