NCU link with different interpolation cycles

Problem description
In the engineering world, parts which deviate slightly from a precise round/cylindrical shape
are also required. (Example: Pistons that are oval in the manufacturing state. The operating
temperature gives them their required almost round shape during use). Eccentric shapes
include, e.g.:
● Oval shapes
● Trefoil shapes
● Cams
● More complex shapes
If you want to manufacture parts belonging to this category cost-effectively on turning
machines, you can use the link functions described below, which are an extension of the link
functions described in "NCU link" and the following sections. The supplementary conditions
must be complied with, however.
