Complex 3D structures

With a large depth of focus and a coaxial measurement configuration, complex 3D geometries can be easily measured. Automatic inspection recipies are freely customizable and greatly shorten the inspection time.

Example: distance between circles

Specifying two circles on the measured data instantly returns the distance between their centers. Other types of dimensional measurement can be easily performed:
・Circle center-to-center distance
・Point-to-line distance
・Flatness
・Step assessment

Automatic assessment recipes

Easy recipe creation.
Allows automatic evaluation of multiple units.
From a regular sampling inspection, one can instantly implement a fully automated inspection of multiple units.

Visual and dimensional inspection all at once.

You can obtain the 3D geometry shown in the right figure with a single measurement. From here, a range of data can be calculated and extracted: volume calculation, surface flatness, defect detection, depth measurement of scratches and more.

Example:Cylinder head

Even a cylinder head with a mix of casting components and machined surfaces can be inspected without difficulties. Even the optical comb laser light scattered by the cast surface can be measured, which allows for complex shape inspection.


Other type of parts:

Conrod, Gear, Oil pump, Camshaft Turbine rotor, Brake rotor, Piston, Timing-chain cover, Cylinder blocks etc.






Helicoidal laser scan, a unique technology

Inner diameter inspection:
bore, cylinder block, break valve, solenoide valve...

The coaxial configuration of our sensor makes it possible to place a mirror on the laser path in order to refract the light before measurement/inspection. Leveraging XTIA's optical comb laser and rotating the mirror, it is then possible to perform 3D shape measurement and 3D visual inspection on the inner wall of a cylinder while maintaining micrometer-level accuracy. The measured data is developed three-dimensionally and fitted to extract dimensional information. Scratches and burrs are detected quantitatively.

Full inspection of the chamber volume
Reduction of volume variation below 0.05cc

Total chamber volume measurement

The volume of the cylinder head chambers can be measured with an extremely small error. Even for complex geometries, the laser does not interfere with the inspected structure, owing to the coaxial configuration of our sensor. As a result, XTIA sensors can achieve a very high repeat accuracy. Furthermore, since the measurement method is not affected by ambient light or light reflected on the target object, extremely high reproducibility can be achieved on the production site, thus enabling a fully reliable inspection process.

Advanced mathematical modeling

In addition to the optical comb laser that enables the 3D measurement of complex geometries, advanced mathematical modeling ensures measurement errors that meet customer requirements. On top of the highly reproducible measurement data, the number of data points is very large, so the mathematical modeling can be performed with a high accuracy based on actual data. By feeding forward the information of the total volume to the fabrication process, error corrections can be introduced into the process flow and the variation in chamber volume can be reduced to its utmost limit.

Simultaneous inspection of defects

The optical comb sensor can acquire 3D profile data in a single measurement. With this data, one can not only measure the chamber volume but also the condition of the processed surface, making it possible to simultaneously measure surface scratches. Depending on the maximum acceptable size of surface scratches, either the wide-range sensor L90 or the high-definition sensor S40 may be required, so XTIA will adapt its sensor design to the customer's request. By automating processes that had until now been relying on the human eye, our optical comb laser sensors makes it possible to upgrade to fully digital data.

Quantitative assessment of defects based on depth, area, volume, cross-sectional area etc.



Defect detection

Using 3D data with micrometer accuracy, one can set clear criteria for automated defect inspection. Regardless of subjective variations of the human eye, XTIA makes defect inspection reliable and thus contributes greatly to quality improvement.



Identifying burrs and scratches

With 3D data, spots, burrs and scratches can be easily distinguished. For defect detection, it is possible to set the depth and height of spots and burrs as well as the volume of the defects as threshold values, making it possible to perform quantitative visual inspections on parts for which airtightness is required.
Note: Dimensionless blemish is not actually observed by the optical comb sensor.

Unaffected by ambient light

Since our sensors are based on the specificities of XTIA optical comb lasers, the measurement laser can be distinguished from ambient light and the measurement itself is not affected by the light environement. As a result, our laser measurement method can be easily adopted to build reliable data even at production sites where there is a signifi cant amount of ambient light.



Compensation of the robot arm vibration

Robot arms generally suffer from vibrations that would greatly affect measurement accuracy, making it unsuitable for high-precision measurements. XTIA has however succeeded in preserving its sensor's micrometer-level accuracy by controlling the vibration of the robot arm. This opens the path to new dimensions inspection and measurement: it is expected to greatly improve the breadth of the system that will support measurement of various types of structures and shapes. XTIA robot-arm with the high-definition sensor S40 and the wide-range sensor L90 will be released sequentially.

High accuracy at all angles

Combining a high definition sensor (40x40mm area scan) with a robot arm. This makes it possible to measure any location with micrometer precision.
