Precision at the Point of Connection
High-Speed, Micron-Level Bore & Interface Inspection
Industry: Automotive ComponentsApplication: Sprocket / Drive-Shaft InterfaceTechnology: 3D Profiling + 2D Vision + Vision AI
The bore and keyway form a critical mechanical interface between the sprocket and drive shaft. Even micron-level deviations can affect fitment, alignment and torque transmission.
The manufacturer needed to detect:
Undersized / Oversized Bore | Out-of-Round Bore | Keyway Width & Depth Deviation | Angular Keyway Offset
A high-speed inspection architecture combines 3D profiling for dimensional accuracy with 2D vision for positional and geometric characteristics. The two inspection streams are synchronized and evaluated against the specification of the specific component variant.
The 3D profiler captures the bore and keyway geometry as a high-resolution 3D profile, enabling non-contact measurement of critical interface dimensions.
It is used to evaluate:
The system performs these measurements against micron-level tolerance limits, providing precise and repeatable inspection of the shaft–sprocket interface.
A high-resolution 2D industrial camera captures the keyway and surrounding interface using controlled diffused illumination.
The vision system analyzes:
Image processing identifies the relevant edges and reference features, allowing the system to calculate the angular and positional deviation of the keyway relative to the bore reference.
Diffused lighting helps minimize glare, reflections and inconsistent illumination from machined metallic surfaces, improving edge detection and measurement stability.
The inspection engine combines the 3D dimensional measurements and 2D positional measurements to make the final interface-quality decision.
For each component, the system identifies the applicable:
Part Variant → Customer Specification → Inspection Recipe → Tolerance Limits
The inspection logic then evaluates every critical characteristic against its specified limits and generates an automated:
For failed components, the system can identify the specific Bore or Interface Error, such as:
Bore Oversize | Bore Undersize | Out-of-Round Bore | Keyway Width Deviation | Keyway Depth Deviation | Angular Keyway Offset
This creates a single integrated inspection solution for the complete bore-to-keyway interface, rather than treating each defect as an independent inspection.
Designed for 9-Second Production Cycles
The 2D and 3D acquisition, measurement and decision processes are optimized to operate within the 9-second production cycle, enabling micron-level bore and interface inspection without slowing the production line.
ENGINEERED FOR PRODUCTION SPEED
The inspection system was optimized to match the 9-second production cycle, allowing critical bore and interface characteristics to be inspected without slowing production.
9 Seconds: Production Cycle = Inspection Cycle
BUILT FOR VARIANT GROWTH
A recipe-driven architecture manages different:
Bore Dimensions → Keyway Specifications → Micron-Level Tolerances → Customer Requirements
New component variants can be added through inspection recipes without redesigning the complete system.
