Wish to cut some simple pipe bending rollers with a half round edge grooves 1/8, 3/16, 1/4 etc.
Programming is simple, but :-
Tooling :-
First option is to use >1/8" RNMG insert but of course too small to be practical.
2nd - Make an HSS form tool with side relief. Possibly on a parting blade. Difficult to get the rad. accurate?
3rd - Use a 35 deg 04mm rad tool and approach from two sides with R&L/H tool.
Any advice on good way to CNC these grooves very much appreciated.
