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. Sanei 1.65K subscribers 189 videos A series of lectures and examples for mechanical engineering topics. Not sure if it’s as high a quality though. Autodesk Inventor Projects 46 views1 year ago Featured Mechanical Engineering with Dr. Seems pretty quick and easy if you can get the materials. 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. Haven’t made one myself, but I used a keyway broach somebody made in our shop the other day. Windchill Workgroup Manager 10.0 Autodesk Inventor. Do you have any links on this? Have you made your own broaches? This sounds interesting. Only the Inventor Workspace of the default project should be set to the Windchill Workspace.
