Hommel-Etamic wavemove: Fully Automated Measurement of Large Workpieces
The wavemove measuring instrument allows you to simultaneously measure the contours and roughness of your cubic or wave-shaped workpieces.
The Hommel-Etamic wavemove measuring systems allow individual, CNC-controlled, fully automated roughness and contour measurements to be performed directly at the production line. Up to eight independent CNC axes position the workpiece and measuring system at all required measurement positions, ensuring precise measurement of all necessary features — fully automated without any operator intervention.
Workpiece-specific fixing devices make it easier to load and unload workpieces. If required, the workpieces can be automatically identified and assigned to the quality data.
These measuring systems are particularly suitable for the measurement of crank shafts, cylinder heads and cylinder blocks. Thanks to the robust design and the optional safety equipment, the measuring systems can be operated in the production environment itself. Small quality control loops and fully automated measurement runs allow you to take the lead in quality management.

Customized and fully automatic
If you have specific requirements, then we have the right metrological solution. We can give you a specific example to show you how this solution might look. Our client from the automotive industry commissioned us to configure a fully automatic roughness and contour measuring station for the measurement of its cylinder heads.
Requirements of the measuring station
- Random sample measurement in the measuring room close to production area
- Loading of the measuring station via existing overhead crane
- Fully automatic measurement and evaluation of the defined roughness and contour characteristics on cylinder heads, including valve seat
- Measuring run in a single clamping operation in compliance with the specified cycle time
- No retrofitting of the probing systems
- Low employee involvement thanks to automated processes
- Compliance with the space restrictions at the installation site
- Safety equipment for safe measurement runs (for operator and component)
Solution — The Hommel-Etamic wavemove
With up to eight fully automatic movable axes, the Hommel-Etamic wavemove can accommodate as many measuring points as required and measure both roughness and contours in a single measuring run. The high degree of flexibility in the positioning of all axes means that the probes can access almost any point on the workpiece.
Optimally adapted: Measuring station configuration in accordance with the local specifications
- Adapting the measurement set-up to local conditions:
- Compliance with the maximum floor space and height
- Extremely low design allows the loading of the measuring station via the overhead crane at the specified installation height
- Measurement layout on the granite plate is adjusted for the measuring tasks
- Ergonomic layout with enclosure for PC, control system and accessories
- wavecontrol joystick control panel for a simple and secure approach to the measuring position with a view of the workpiece
- Swiveling workpiece holder (B-axis) for fully automatic measurement of the edges and radii of the valve seat
- Active level control with integrated vibration damping for compensation of common building vibrations
- Eight CNC-controlled axes with high levels of positioning accuracy to control any number of measuring positions
- Integrated storage for safe retention of the roughness and contour standards
Clear assignment for clear measurements: Roughness and contour probing systems with integrated probe arm detection
- Probe arm detection via RFID technology with automatic assignment of the measuring task
- Enables reliable measuring runs, as unintentional manipulations and unwanted collisions are avoided
- No retrofitting of the probing systems, roughness and contour probes are operated in parallel
- Sophisticated layout for the exclusion of interference contours during roughness measurement
Secure processes with automatic identification of components: Clamping device with integrated scanning.
- Specially developed clamping system for holding the cylinder heads mounted on adapter plates
- Secure fixing of the component to the mounting plate: Clamping and release only possible in 0° position so that injuries or damage to machines or parts are ruled out
- Automatic clamping of the component
- Automatic detection of the workpiece via RFID code (e.g. type and processing level) in the adapter plate, so the component can be clearly assigned to a measuring program
