Define curve tables (CTABDEF, CATBEND)

Function
A curve table represents a part program or a section of a part program enclosed by
CTABDEF at the start and CTABEND at the end.
Within this part program section, unique following axis positions are assigned to individual
positions of the leading axis using motion operations; these following axis positions are used
as intermediate points when calculating the curve definition in the form of a polynomial up to
the 5th order.
Condition
The MD must be configured accordingly to ensure that sufficient memory space is reserved
for the definition of curve tables (→ machine manufacturer).
