I’ve made a part for a customer for 10+ years
6 a year not a high volume, part is 2 x 3 x 1.2 aluminum
1st op /detail is a 2.5” radius so the part will saddle a 5” tube to be welded in place
Early runs I used a ½” ball mill with a hand written program cutting along X axis
Moving in Y dropping in Z to give a quazi cope
Appearance/finish wasn’t to important as the cope was used just to clock to the tube.
2nd method was a boring bar set to 2.5 radius in a boring head
Successive Z cuts , moving in X towards blank until needed cope was complete, but still leaving flats to support other side ops.
Although this created a much better part, setting the bar was a pain
What I do now is use a HSS 5” diam 60tooth 1/8” slitting saw I picked up on EEbay used
Cutting 0.020 with each X cut, feeding 18ipm in Z @1600rpm
Very good finish, easy setup
I’m sure many will look and say, yeah do it all the time, if its new to someone my sharing was worth the post
