The Winged Victory or Nike of Samothrace is a statue prominently featured in The Louvre Museum in Paris, France. Mastercam recently teamed up with YASDA Precision, Mitsubishi Materials, and Methods Machine Tools to create an 11-inch replication of the famed 18-foot statue.
Within Mastercam, the statue is a mesh file with over five million facets and was 10 gigabytes in size. Mastercam took the part from a raw piece of stock all the way to a finished part.
“I have never made a part of this caliber in my life” said Mastercam Sales Engineer II, Chad Chmura. The overall cycle time on this project was over 110 hours –just under five straight days!
Since this piece was such a large file, Mastercam created a series of videos on their YouTube Channel to demonstrate the different Mastercam tools used in the making of it, and how those tools are the exact same that you have access to as a Mastercam user.
Here are several highlights of Mastercam features used to create this amazing piece.
Detect Undercut Stock
In Mastercam 2023, the Detect Undercut Stock checkbox was introduced, which allows you to trim all of the air cuts with just a single click of a box. By using this feature, the run time of the toolpath was cut by a third from 18 minutes to 12 minutes. The Detect Undercut Stock checkbox was invaluable on the Nike project because this part was full of hidden undercuts.
Mastercam’s Unified Multiaxis toolpath helped finish the Nike statue as it allowed the YASDA machine to make long sweeping motions in several phases of the project, including the wings and the front of the dress. Since the statue was a mesh file, it was possible to create a wireframe on any point of the mesh, so drive curves were created that followed the wrinkles of the dress’s curvature.
Using this as a guide curve in Unified Multiaxis, made it possible to control the step-over in a way that followed the exact contour of the dress, which made the step-overs of the toolpath blend into the profile of the part.
Advanced Holder Checking
When programming a part as complex as the Nike statue, it is crucial to keep our tool and holder safe. Mastercam can apply holder checking, which means you can trim your toolpath motion or create tilt motion anytime your tool holder will interfere with the part.
While working on the Nike statue, Mastercam had to keep the toolpath moving without any collisions. Mastercam’s Check Holder function allows you to calculate a safe minimum tool projection for all of your Mill toolpaths.
