3D Inspection on Automobile Wheel Cover Rebounding Deformation

Mar 22, 2019

What does the customer need?

Rebounding is one of the defects in sheet metal stamping, which seriously affects the quality and dimensions of the stamping part. It is an urgent problem that needs to be overcome. However, traditional measurements such as caliper and micrometer, they can’t detect the deformation of automobile wheel cover due to curve surface, so it’s hard for manufacturers to improve products’ quality.

ScanTech 3D solution

Comparing with traditional measurement, ScanTech delivers a cost-effective way to scan the whole automobile wheel cover within 20 minutes. ScanTech will combine handheld 3D scanner HSCAN331 with MSCAN photogrammetry system.

HSCAN 3D scanner can be conveniently carried to workshop and stable in a different environment to perform highly accurate 3D scanning. MSCAN photogrammetry system is usually used for measuring and positioning large volume, it can work with handheld 3D scanner to decrease the accumulative errors, and can also work individually to measure dimension and geometric deformation

Step 1: get dimensions of wheel cover by MSCAN photogrammetry system
