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.
Coefficient a
0
of the function definition FCTDEF( ) is evaluated with FTOC.
The maximum and minimum limits are determined by a
0
.
This means that you can also program modal, online tool offsets or clearance controls as
synchronized actions.
This 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 supplementary conditions and specifications for dressing grinding wheels apply to FTOC
in the same way that they apply to tool offsets using PUTFTOCF. For further information,
please refer to "Tool Offsets" section.
Programming
FTOC(Polynomial_No., RV, Length1_2_3 or Radius4, channel, spindle)
Parameters
DO FTOC Perform online tool offsets
Polynomial_No. For polynomial defined with FCTDEF, see Subsection
"Polynomial definition" in this Section.
RV Main run variable for which a function value for the
specified polynomial is to be calculated.
Length1_2_3
Radius4
Length offset ($TC_DP1 to 3) or radius offset to which the
calculated function value is added.
Channel Number of the channel in which the offset is active. No
specification is made here for an offset in the active
channel. FTOCON must be activated in the target channel.
Spindle Only specified if it is not the active spindle, which is to
be compensated.
