I and others on the list have cut thin gears working the side of a small diameter end mill. Wooden clock gears are are commonly done this way. I just created a path for one tooth, http://www.wallacecompany.com/machine_shop/gears/ then rotated enough copies to complete the gear in QCAD. I converted the QCAD file to G-code and ran it in XYZ on my mill. Using the tip of a ball end mill with an A axis could be the same, but one would most likely need a fancy 3D CAD/CAM. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
