Siemens SINUMERIK 808D ADVANCED Parameter Manual page 139

Description:
This machine data is evaluated only if MD28540 $MC_MM_ARCLENGTH_SEGMENTS is greater
than 0.
The factor indicates how large the relative error of the path velocity may be for
splines, compressor and polynomial interpolation. The smaller the factor the more
computing time is required for preprocessing.
Furthermore, more memory is required to display the arc length function (see 28540
$MC_MM_ARCLENGTH_SEGMENTS).
Example:
SPLINE_FEED_PRECISION=0.1, programmed path velocity=1000 mm/min.
The actual path velocity for polynomial and spline interpolations may then vary within
the range between 900 and 1100 mm/min.
20270 CUTTING_EDGE_DEFAULT
- Initial position of tool cutting edge without programming
-
- -
Description:
Default cutting edge after tool change
If no cutting edge has been programmed after a tool change, the default cutting edge
number set in MD20270 $MC_CUTTING_EDGE_DEFAULT is used.
Value
:= 0
Initially, no cutting edge is active after a tool change.
The cutting edge is not selected until D programming.
:= 1
MD_SLMAXCUTTINGEDGENUMBER
No. of cutting edge (MD_SLMAXCUTTINGEDGENUMBER=9 is valid up to P4)
:= -1
Cutting edge number of old tool also applies to new tool.
:= -2
Cutting edge (correction) of old tool remains active until D is programmed. This means
that the old tool remains the active tool until D is programmed. In other words, the
tool on the spindle remains the programmed tool until D is programmed.
Example:
MD20270 $MC_CUTTING_EDGE_DEFAULT = 1;
After a tool change, the first cutting edge is active if no other cutting edge has been
programmed.
20272 SUMCORR_DEFAULT
- Initial position resulting offset without program

808d-te42 -
808d-te62 -
808d-mte40 -
808d-mte60 -
Description:
The number of the total offset of the cutting edge which becomes active when a new
cutting edge compensation is activated without a programmed DL value being available.
MD18110 $MN_MM_MAX_SUMCORR_PER_CUTTEDGE
defines the maximum useful value which can be entered.
