    Manual tool comp on partial radius (Lathe)

    I've been trying to figure out on my own how to manually calculate the tool nose compensation on a partial radius for a while now and i just can't seem to get it. However, I can get it right when i use the formula for tool comp on a straight line. So basically my question is: Is the formula for figuring out tool nose radius compensation the same for angles as well as for radii?

    Here are the formulas i am using:

    z axis comp= nose radius-(nose radius x tan(angle [divided by] 2))

    x axis comp= 2 x [nose radius-(nose radius x tan(45- (angle [divided by] 2))]

    from the theoretical sharp corner trig out start finish points of the arc + tnr for .1 arc and .0312 tnr .1312 arc then program r value .1312 hope this helps.
