Machinists,
I need your help!
I'm cutting a crescent shape radially into 1" aluminum round.
Have my start and end points. But for some reason the crescent is too flat on the bottom, not smooth arc.
I think I have it narrowed down to not having K in the right spot. The instructions I'm using say the K is the center point of the arc.
What's confusing me is where to put the center of the arc: Is it the radius (measured from the bottom of the arc up? or actual distance the center of the arc is above Z0?
Top of rod is Z0. Since the depth is .2" and the radius is .551" would I set K to z.351" or z.551"
Does the ijk method only allow 90deg arcs max?
Thanks, MM
