NCU (residual boring marks after honing of cylinders) detection requested by power train.
Applicable scattering phenomenon observed in laboratory.
Defect detection: Go/No-Go vs. conventional metrology.Project Background
The physical phenomenon used to distinguish between boring and honing:
Laser light normally incident on a machined surface is scattered preferentially in a plane perpendicular to the machining marks.
Honing Problem Detection detection requested by power train.
Different honing patterns at the top and bottom of the cylinder
Axial stripes along the cylinder wall.
Fine and Coarse Boring
Technology transfer to industry. detection requested by power train.
Demonstrate parallel probe operation.
Demonstrate survivability and maintainability of probes in a factory environment.
Accelerate implementation in ERC member company plants.Full Scale Prototype Goals
Demonstrate parallel operation.
Inspect blocks from different manufacturers-straight 4,V-6, and V-8.
Minimum cost.Full Scale Prototype Requirements
Probe rotation mechanism
Inspection station computer
Fork lift holes
Vibration absorbing pads
Gehring machine head
Factory implementation of prototype system.
Possible detection of rough hone or boring stages.
A probe to measure dimensional variation and detect NCU is being developed.Future Work
New probe will measure dimensional variation as well as
check surface finish.
Probe centering in a cylinder will be easily determined using this probe.
Probe uses different detector, electronics, optics and software.
Image position changes with distance from probe to surface.
Detector is position sensitive.Dimension sensing probe
