3D CAD Modeling for Manufacturing: Cuts Like a Knife

A manufacturer and supplier needed 3D scanning and CAD modeling to move a part of their operation to the U.S.

The Customer:

The country's largest commercial knife rental and sharpening service. They serve more than 49,000 customers, including some of the most recognizable restaurant and grocery chains in the United States. From the corner deli to industrial scale, this company serves any size operation. They got their start in Chicago, IL in the early 1900's and soon after, grew to a national company.

The Challenge:

The customer needed a 3D scan of an industrial food processing blade and a usable 3D CAD model from Solidworks in order to manufacture the part. Previously, parts were being imported from Europe and the cost per unit was becoming prohibitive. The customer needed to be able to manufacture the blade in the United States.

Service We Offered:

  • We began with the 3D scanning process. For this we used our Zeiss Metrotom 800 CT (x-ray computed tomography) machine to gather the data and geometry needed for the design phase.
  • From there, an .STL file was created from the raw CT scan dataset.
  • The .STL was imported into Geomagic Design X. This is a 3D reverse engineering design software. It has the ability to process large datasets with millions of points per scan. It's the program Nel PreTech uses to create high quality, feature-based CAD models.
  • The .STL was used as a scaffold to create a 3D CAD model.
  • The CAD model was exported from Geomagic Design X in a .STEP format for the end deliverable to the customer.
Final Deliverable: 3D CAD Model of Industrial Scale Food Processing Blade

Results Achieved:

Our designers were able to provide a 3D CAD model with speed and accuracy. Results were provided in a .STEP format which can be opened and read universally across all CAD/CAM software packages. In the end, the customer is saving time and money by being able to manufacture the part in the U.S.
