on the above subject I have a following situation:
1. This is the definiation of a Ball end milling cutter in NX (9.0) with a taper angle in metric unit
D = 10 B = 5 L = 75 FL = 50 (other paramters are not relevant for this issue)
2. Belwo is the output of the same tool in NX-CLS format (from command << AnyCAM Operation>>[Actions] -> List)
The first "9.1633" represent the value of tool diamter at the interface of toolchaft and the tool's ball end.
I need to know how is this value calculated. According to my calculation this value should be 9.96194 (by using Dc = D * cos(B) for the length of chord at the tangent intersection of tool shaft and ball-end).
