Define Curve Tables (Ctabdef, Catbend) - Siemens SINUMERIK 840D sl Programming Manual

11.2.1

Define curve tables (CTABDEF, CATBEND)

Function
A curve table represents a part program or a section of a part program enclosed by
at the start and
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.
Requirement
The MD must be configured accordingly to ensure that sufficient memory space is reserved
for the definition of curve tables (→ machine manufacturer).
