    I purchased a new V-bit that I wanted to try.  My problem is I cannot get it set up in ESTLCam.

    The bit is a 30-Degree V-Bit, 3.175mm Shank and a 0.2mm Tip. The tip is the problem.  How do I tell ESTLCAM that it is not a point, but a blunt end of 0.2mm?

    I think I need to do something with the Tip Offset setting in ESTLCAM, but I do not know how to get the number to enter.

    If anyone knows the calculation I would love to have it.

    offset is -(0.2mm/2)*tan(75)

    Thanks.

    That started the brain and I now remember.

    I drew it up so that it may help someone else.

    It is  tan(Θ) = a/b

    a = half the width of the blunt end of the bit

    b = the distance from the blunt end to the where the tip should be

    Θ = half the angle of the V-bit

    tan(15) =.1/b

    b = -.116823
