Custom made guitars are works of art created by hours of shaping and sanding by hand by a skilled luthier. However, creation of a 3D CAD model is required for mass production.
Trying to recreate the guitar from hand measurements or have a luthier duplicate the original may produce a nice guitar, but will it will not likely maintain the same sound quality or “feel” of the original.
- Original part (Figure 1) is Laser scanned in house using the Konica Minolta Range 7 scanner. (accuracy of .0015”)
- Scan Data is registered, merged, and aligned in Rapidform XOR to produce a polygon mesh (Figure 2).
- Mesh is used as a reference to create a parametric solid model in Rapidform XOR.
- Feasible to obtain quality data previously unavailable by other means.
- Final CAD model is parametric, and can thereby by easily updated or modified in customer CAD system.
- Feature based model consisting of trimmed surfaces provides for easier CAM programming, than other “rapid surfacing” techniques.
