Synchronized axes
If a number of paths need to be synchronized (e.g., contour, special axis), then every path
must always have its own rounding area.
There are no practical means of achieving this exactly. Therefore, on the basis of the specific
meaning of the contour (geometry axis), the following procedure is applied:

2 A block transition G64 (continuous-path mode without rounding) can be traversed
without speed reduction. Rounding would increase the machining time.
Rounding is not parameterized. This occurs when ...
1 ADISPOS == 0 in G0 blocks. (default!)
2 ADIS == 0 in non-G0 blocks. (default!)
3 On transition from G0 to non-G0 or non-G0 to G0 respectively, the smaller value from
ADISPOS and ADIS applies.

are smoothed
