In blocks with short distances (distance < 4*ADIS and < 4 * ADISPOS respectively), the
rounding distance is reduced so that a traversable part of the original block is retained. The
remaining length depends on the axis path and is approximately 60% of the distance still to
be traversed in the block.
ADIS or ADISPOS is therefore reduced to the remaining 40% of the distance to be traversed.
This algorithm prevents a rounding block being inserted for a very small change in contour.
In this case, switchover to continuouspath mode G64 is automatic until rounding blocks can
be inserted again.
