Solution
AUTOMOTIVE / 3D PROFILE
3D surface profile inspection
Automotive steering shafts · Racks
Inspect wear and structural abnormalities in automotive steering shafts and racks after durability or impact testing.
SCAN → RECONSTRUCT → INSPECT
From external profiles to 3D analysis.
02
Point-cloud reconstruction
Combine successive profiles into a point cloud and reconstruct the teeth and external surfaces.
03
Inspection & analysis
Analyze shape, distances and surface flatness in the point cloud to assess wear and structural abnormalities.
Scan external profiles with a 3D laser profile sensor, reconstruct the point cloud and analyze shape, distances and surface flatness.
INSPECTION SCOPE
Focus on changes after testing.
Wear & structural abnormalities
Examine profile changes in shafts and racks after durability or impact testing.
Shape & distance
Analyze tooth profiles and local geometry in the 3D point cloud and measure distances.
Surface flatness
Assess surface geometry and flatness to support review of abnormal regions.
