Compensation; Frames; Tool Offsets - Siemens sinumerik 840D sl Function Manual

3.2.6

Compensation

RESU can be used in conjunction with compensations as the traversing movements of the
first two geometry axes on the channel are recorded in the basic coordinate system (BCS)
and therefore before the compensation.
You will find a complete description of the compensations in:

3.2.7

Frames

RESU can be used in conjunction with frames.
However, as the traversing movements of the first two geometry axes on the channel are
recorded in the basic coordinate system (BCS) and therefore after the frames have been
taken into account, the frame offsets must be deactivated during retrace support
(reverse/forward travel).
The frame offsets are deactivated during retrace support via the standard default settings of
the RESU-specific subroutine CC_RESU_INI.SPF. See Subsection "Detailed description /
RESU-specific part programs / INI program (CC_RESU_INI.SPF)".

Tool offsets

Meaning
RESU can be used in conjunction with tool offsets.
However, as the traversing movements of the first two geometry axes on the channel are
recorded in the basic coordinate system (BCS) and therefore after the frames have been
taken into account, the tool offsets must be deactivated during retrace support
(reverse/forward travel).
The tool offsets are deactivated during retrace support via the standard default settings of
the RESU-specific subroutine CC_RESU_INI.SPF. See Subsection "Detailed description /
RESU-specific part programs / INI program (CC_RESU_INI.SPF)".
Contour deviations
Specific instances of tool radius compensation, e.g. compensation on outside corners G450
DISC=x, may generate contour deviations between the contour traversed during retrace
support and the contour programmed in the machining program.
