Combine short spline blocks
Spline interpolation can result in short spline blocks, which reduce the path velocity
unnecessarily. The "Combine short spline blocks" function allows you to combine these
blocks such that the resulting block length is sufficient and does not reduce the path velocity.
The function is activated via the channel-specific machine data:
MD20488 $MC_SPLINE_MODE (setting for spline interpolation).
