    Tool: Ball Nose definition in BobCad

    Under Tool definition/selection on the NC-side of things in BCC, how do you define a ballnose cutter? There are only D and E parameters. Would a 3/16" dia. shank, 3/16" diameter ball nose cutter be: D=0.1875 and E=0.1875 or D=0.1875 and E=.125 (or some formula derived value)?

    Thanks,

    Rob

    D=.1875
    E=0.0

    E= is the diameter of the tool tip. If you were using a 1/2 Diameter BULL NOSE with a .125 Corner Radius it would look like this:


    D=.5
    E=.25

    Chasing threads!

    So for a BALL vs BULL nose the E = 0 since the point at the tip is the core diameter - E. I see. Thanks again, Toby.
