10.4.9 Online tool offset (FTOC)
Function
FTOC permits overlaid movement for a geometry axis after a polynomial programmed with
FCTDEF depending on a reference value that might, for example, be the actual value of an
axis.
The coefficient a
0
of the function definition FCTDEF(...) is evaluated for FTOC. Upper and
lower limit are dependent on a
0
.
FTOC can be used to program modal online tool offsets or clearance controls as synchronized
actions.
The function is used for the machining of a workpiece and dressing of a grinding wheel in the
same channel or in different channels (machining and dressing channel).
The general conditions and specifications for dressing grinding wheels apply for
FTOC in the
same way that they apply for online tool offset with
PUTFTOCF (see "Online tool offset
(PUTFTOCF, FCTDEF, PUTFTOC, FTOCON, FTOCOF) (Page
404)").
