GOM Touch Probe (Add-on)
Enhance ATOS with Touch Probe Measurements
The GOM Touch Probe is an ATOS add-on option that enables 3D discrete point measurements in conjunction with ATOS full-field measurements for direct comparison to CAD for difficult to access areas, hidden cavities, discreet points and primitives. Touch probe data can also be utilized for online data alignment. For non-standard applications, customized probe tips and adapters are available.
- Combine full-field non-contact scans 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.
The GOM Touch Probe is introduced into the below video at the 1 minute and 27 seconds mark.
Combining Non-Contact 3D Scanning with Tactile Probe Measurement
Only ATOS dynamic referencing allows the object or the sensor to be easily and freely moved or positioned. The sensor and object do not need to be fixed in relation to each other, allowing for flexible measurement planning and access to all sides, without complex respanning or reclamping of the 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
The 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 for easy interchange of probe heads and extenders. Furthermore, the user can create customized touch probes for specific tasks.
The GOM adapters further provide advanced possibilities for online measurement used for:
Custom Probe and Adapters
As with the touch probes, the adapters are also customizable and can be developed to fit any task or geometric form.
