GOM Touch Probe
Optically Tracked GOM Touch Probes
Many complex metrology applications require the combination of full-field and point based 3D measurement. The GOM Touch Probe is an add-on to the ATOS 3D Digitizer:
- Full-field and touch probe 3D measurement
- Measurement in difficult to access areas
- Comparison directly to CAD
- Measurement of primitives
- Quick measurement of individual points
- Online alignment
The GOM Touch Probe is a calibrated set of point markers which are optically tracked by the ATOS 3D Digitizer. ATOS delivers a full-field polygon mesh describing an object’s surface precisely and the online 3D coordinates of the touch probe.
Combining Scanning and Tactile Measuring
Only the ATOS dynamic referencing allows the object or the sensor to be easily and freely moved or positioned. Sensor and object do not need to be fixed in relation to each other allowing a flexible measurement planning, reaching all sides, without complex respanning or reclamping of sensor or part.
The lightweight (avg. 100g) GOM Touch Probe allows effortless measurement over long periods and for larger measuring projects. No internal electronics or cables are used guaranteeing high stability and unrestricted reach.
Complete Hardware and Software
ATOS and Touch Probe measurements are carried out with one system and are evaluated with one software package. No extra hardware or tracker is required, enabling quick measurement procedures and easy interchange between surface and single point measurement and analysis.
Measurement of Small to Large Objects
Five standard touch probe sizes are available for small to large objects – from the measurement of an alignment hole on a small injection molded part with the GOM Touch Probe PM1.5 to cooling channels of a large casting with the GOM Touch Probe PM18.
The touch probes have been developed to adapt to many different applications. The standard M5 thread on the PM3-PM18 touch probes allows easy interchange of probe heads and extenders. Furthermore, the user can create customized touch probes for specific tasks.
The GOM Adapters provide further and advanced possibilities for online measurement:
- Alignment of components
- Adjustment of fixtures
- Determination of trimming & springback
- Fast online measurement of primitives and edges
As with the touch probes, the adapters are also customizable and can be developed to fit any task or geometric form.
