I've seen videos of turbine wheels being cut with a ball nose straight end mill on a 5 axis machine. Why not cut involute spur gears on a 4 axis with end mills?
Can LinuxCNC do that? Would be hellaciously less expensive than buying all those sets of 8 cutters to cover different diametral pitches and pressure angles. Hobs come in a bit less since you only need one hob per DP and PA to cut any number of teeth but also need a spindle encoder to synchronize the 4th axis. End mills + software = way cheaper. Probably slower than using individual cutters, certainly slower than hobbing, but should be as accurate as hobbing where the 8 cutters are only accurate at the lowest number of teeth for each one. ------------------------------------------------------------------------------ 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
