Problem:

Townley Engineering and Manufacturing had aging volute molds that needed to be replaced. They wanted to recreate there molds by cutting them on a CNC machine.

Traditional Method:

To recreate the organic geometry found in the volute you need to use a combination of calipers, a tape measure, and cardboard patterns. This method is inaccurate and can create problems when you have existing parts that need to mate up.

NeoMetrix Solution:

• Scanned in house using the Vivid 9i wide lens (accuracy of .008”) (Figure 1)
• Scan Data is registered, merged, and aligned in Rapidform XOR. (Figure 2)
• Sketchs and curves are generated based upon the scan data in order to develop a parametric solid model. (Figure 3)

NeoMetrix Advantage:

• Geometry is modeled to original design intent.
• Organic shapes and handmade radii accurately reconstructed.
• Clean IGES file ready to be CNC machined.
