Bit12:
The tool parameter $TC_DP15 is not interpr eted as wear of the tool radius but
as wear of the tool diameter.
Bit13:
During JOG of circles, the circle center coordinate is always a radius value,
see D42690 $SC_JOG_CIRCLE_CENTRE.
Bit14:
Bit15:
Bit16:
For GWPS (GWPSON/TMON), the tool parameters tool length, wear and base dimen-
sion are interpreted as diameter values
Bit17:
With cutting edge position compensation (CUTMOD) for turning and grinding
tools, the cutting plane for calculating the compensation values is rotated
into the machining plane. If this bit is not set, the cutting edge is pro-
jected into the machining plane instead.
Bit18:
With cutting edge position compensation (CUTMOD) for turning and grinding
tools, always use the active plane (G17 - G19). If this bit is not set, the
plane specified by setting data sD42940 $SC_TOOL_LENGTH_CONST has priority
over the plane specified by the G code group 6 (plane selection, G17 - G19).
Bit19:
The tool orientation change caused by an orientable toolholder becomes effec-
tive even if no tool is active. This bit is only effective if Bit 10 is also
set.
Bit20:
If this bit is zero, and if the tool parameter $TC_DP10 (holder angle) and/or
$TC_DP24 (clearance angle) contain the value 0, for the function CUTMOD to
calculate the modified cutting-edge position and the modified cutting-edge
direction, the following default values are used as basis:
Holder angle 112.5 degrees for cutting-edge positions 1 - 4
Holder angle 67.5 degrees for cutting-edge positions 5 - 8
Clearance angle 22.5 degrees for cutting edge positions 1 - 4
Clearance angle 67.5 degrees for cutting-edge positions 5 - 8
If this bit is set, in the mentioned cases, an alarm is output. This bit is
used to establish compatibility with older software releases.
