Story-Worthy Engineering Services

Built for responsiveness.

QC Engineering strives to provide services worth telling others about. We've structured our entire operation to be responsive to your needs – from precision equipment to be used on your type of parts, to IT systems built for optimum communications; we strive in every way to provide story-worthy service.

To take you to the next step.

When you begin a project with us, we'll want to know your stated and unstated project needs. We value making and keeping aggressive commitments to help you get to the next step in your project. You’ll know the accuracy of the CAD model we provide by attending a live on-line review of the CAD geometry compared to the scanned part.

Scanning Outputs

Point Cloud

• Raw 3D Scan Data (.txt, .asc)

Generated by all 3D scanning technologies, raw geometric data is collected as a point cloud. This is the first step in every project.

Polygons

• Raw 3D Scan Data with a polygonal wrap (.stl)

Neutral file primarily used by the 3D printing industry.

Analysis

• 2D Visual Report (.pdf)
• 3D Interactive Report (.pwzip)

Point cloud data is overlaid to an existing CAD model or scan data of another part to show deviation. Used for rapid design verification, tooling validation, and first article inspection.

Referred to as a Deviation Analysis, Comparative Analysis, Computer Aided Inspection (CAI) or Verification (CAV), or Color Map. Reports can also be manipulated to show specific dimensional call outs or FAIs. We call this a "CAV Plus".

Modeling Outputs

Native Parametric Formats

Models developed in your native CAD platform. Constructed with a fully functional design tree, robust models are built for ease of editing.

NURBS File Format

Best for modeling organic shapes that do not need to be edited. Surface or solid file output (.igs, .stp)

All Reverse Engineering and Modeling project customers receive a Live Model Review at project completion.

When you may need dimensional inspection vs 3D scanning.

Is your project in its final validation (first article) stage?

A 3D scan may be an acceptable final validation for your project. However, if you need complete dimensional results as specified by the part print, a full FAI using a CMM or other inspection tools may be a better solution.

Do you need accuracy less than 8 microns?

When your tolerances are in the 2-10 micron range, a touch probe or vision CMM is a better solution than 3D scanning. Chromatic white light scanning and confocal micro-laser scanning will produce tighter accuracies, but are limited to relatively flat surfaces, measuring micro-topography.

Does your inspection involve a large number of dimensions?

Measuring multiple features can be done with both a traditional CMM and by extracting the data from a 3D scan. However, it is generally more efficient to extract a few dimensions from a 3D scan than several hundred. As a guide, 20 (or fewer) dimensions on 1 or 2 parts is a good number for 3D scanning. As the dimensions and number of pieces increase, programming and inspecting with a CMM is more cost effective.
