How 3D Scanning Works

A blue light scanner is an optical, non-contact technology that projects a fringe pattern across an object’s surface. Two cameras capture the displacement to calculate the 3D coordinate measurements. This 3D scanning system quickly captures millions of points per scan of a volumetric area creating an accurate and dense point cloud.

With industrial computed tomography (CT), numerous component characteristics are scanned in one run. Using Zeiss Calypso software, even the smallest defects become visible through individual sectional images and can be automatically evaluated according to various criteria. NPC can also load volume data of several components into a project, perform a trend analysis and compare the analysis with CAD data.

3D Scanning Benefits

Today’s industrial marketplace is increasingly competitive and requires the ability to reduce costs, raise production, and increase accuracy for any business that is going to survive. For businesses that will truly thrive, the ability to lead development and get products to market faster is also critical. Advanced 3D modeling can enable this to happen, giving new life to many businesses in a wide array of industries.

Benefits of Reverse Engineering

Part digitization, while very useful, could be limited to partial data or rough data displayed as a point cloud. While this data is useful for inspection purposes, parametric modeling provides information relevant to the original design intent of the part. This includes a solid CAD model or even blueprints.

The model can show a product with imperfections removed and/or a full feature design tree.

Models can be provided in a .stp, .iges, or native CAD format and can be manipulated within CAD software such as Solidworks, Pro-E, IDEAS, AutoCAD, and others.

Digitization / Color Mapping Process

Our part digitization process is based on the capabilities of scanning CMM’s, scanning vision systems, computed tomography (CT scanning), lasers, blue light scanners, and other tools.

This gives Nel PreTech the ability to produce highly accurate and repeatable measurements. It’s this capability that is the cornerstone of our reverse engineering and 3D modeling services.

Color mapping allows information taken from industrial CT, structured light, or other digital scans to be compared to a nominal CAD model.

Comparisons can also be made to other existing part data sets.

You'll get the option of user-definable color patterns for easy analysis of surface variations.

How CMM Inspection Works

The CMM uses an attached probe to take measurements along the three X, Y and Z axes.

Those recorded coordinates give a better understanding of the geometrical features.

Coordinates can be used to virtually replicate the entire object based on its geometrical characteristics.

The ability to obtain this type of data is invaluable for manufacturers and engineers, as it does not require the same level of invasive examination that is typically required in 2D layout projects. We use only the best available equipment, the best possible environment, and rely on the expertise of a well-trained staff.

Large Scale CMM Inspection Services

Nel PreTech CMM inspection services are not limited to small objects. In fact, we operate CMM's capable of taking large-scale measurements for a comprehensive look at objects, heavy machinery, and equipment. Our CMM inspection services help customers map out and get a full picture of large objects by using equipment built specifically for large-scale metrology. Overcoming size and weight challenges for successful first article inspections is a capability NPC takes great pride in.

Maintaining accurate and repeatable dimensions on large scale parts is essential to maintaining quality in industries such as aerospace, marine, automotive, manufacturing, and construction. Inspection processes for these parts can be time consuming and difficult due to size, unusual shape, or weight. NPC is fully equipped to tackle these types of challenges.
