Inspection of metal components with intricate geometries — grooves, deep holes, slots and large surfaces — requires scanning systems able to capture multiple angles without compromising productivity. The crossed XC65Dx scanner, developed by LK Metrology, addresses this challenge with an architecture of three line lasers integrated into a single sensor.
Context and challenge
Conventional linear scanners require multiple passes to fully cover complex geometries, increasing cycle time and positioning error points. The XC65Dx changes this logic by arranging three laser emitters spaced at 120 degrees, observing the part simultaneously from three distinct angles. In this way, a single scan collects the volume of data that a linear scanner would require in three sequential operations.
The solution or technology
The crossed laser configuration ensures extended angular coverage, reducing shadow zones typical in holes, bosses and abrupt geometry transitions. This capability makes the XC65Dx suitable for inspection of body-in-white (BIW), gap evaluation and dimensional alignment, as well as control of transmission cast parts, where surface complexity is high.
According to LK Metrology, the sensor maintains accuracy on sheet metal and casting parts—environments where reflections and surface finish variations can compromise other optical systems. Reducing the number of passes decreases inspection time and simplifies trajectory programming in CMMs or robot cells.
Industrial applications
The XC65Dx adapts to various industrial applications:
- Automotive bodies (BIW): dimensional inspection of welded panels, verification of gaps and alignment of fixings.
- Transmission components: control of castings in aluminium or iron, with complex internal geometries and thickness variations.
- Stamped sheet metal: validation of grooves, holes and embossing in formed parts, reducing measurement cycles.
Results and benefits
The three-laser architecture offers measurable advantages in industrial environments:
- Cycle time reduction: captures in one pass the equivalent of three linear scans, speeding inspection and increasing throughput.
- Lower programming complexity: simplified trajectories reduce setup time and collision risk on CMMs or robotic arms.
- Extended angular coverage: minimizes shadow zones on complex geometries, reducing the need for manual reorientation of the part.
- Data consistency: simultaneous acquisition from three angles reduces variations associated with multiple passes and repositioning.
