![]() It obviously worked for the purpose it was intended for, but I think that it wouldn’t hold up well for FRC purposes. ![]() Also, the end design only has two steps, so two cutting surfaces are removing all the material. It requires a spin indexer and a surface grinder to turn the round high speed steel into hex. This one shows a hex broach being made out of a round piece of high speed steel with a surface grinder. Not sure if it’s as high a quality though. In Inventor 2022, we introduce new functionality which allows us to export a Revit project (.RVT) directly from Inventor. Seems pretty quick and easy if you can get the materials. The Autodesk Vault project is more suitable for projects requiring multiple users using a networked computer system. This video shows a keyway broach being made on a mill. This is the method I think might be most suitable for FRC teams, and I’d be really excited if someone with access to a lathe could try it out and see how it goes (hint hint, nudge nudge). This video shows a square broach being made on a lathe, and it looks like it could easily be done with steel hex shaft. They basically ground the shape on a blank of tool steel, hardened it with a torch and oil quenching, then sharpened it with a grindstone. ![]() too much that it completely blacks out details, the controls for this is in the Shadows tab. Haven’t made one myself, but I used a keyway broach somebody made in our shop the other day. There are three types of lighting methods used in Inventor. Do you have any links on this? Have you made your own broaches? This sounds interesting.
