software option 17)

Cycle parameters

Q263 1st measuring point in 1st axis? (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range -99999.9999
to 99999.9999
Q264 1st measuring point in 2nd axis?
(absolute): Coordinate of the first touch point in
the minor axis of the working plane. Input range
-99999.9999 to 99999.9999
Q294 1st measuring point in 3rd axis? (absolute):
Coordinate of the first touch point in the
touch probe axis. Input range -99999.9999 to
99999.9999
Q320 Set-up clearance? (incremental): Define
an additional distance between measuring point
and ball tip. Q320 is added to SET_UP in the touch
probe table. Input range 0 to 99999.9999
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input
range -99999.9999 to 99999.9999
Q305 Number in table?: Specify the row number
of the preset table/datum table to which the TNC
saves the coordinates; input range 0 to 9999.
Q303 = 1:
If the active preset is modified this change
immediately becomes effective. Otherwise an
entry is made in the specific row of the preset
table without automatic activation
Q303 = 0:
datum is not automatically activated
Q333 New preset in TS axis? (absolute):
Coordinate at which the TNC should set
the preset. Default setting = 0. Input range
-99999.9999 to 99999.9999
Q303 Meas. value transfer (0,1)?: Specify
whether the determined preset is to be saved in
the datum table or in the preset table:
-1: Do not use! Is entered by the TNC when
old programs are read in (see "Characteristics
common to all touch probe cycles for presetting",
Page 370)
0: Write the measured preset into the active
datum table. The reference system is the active
workpiece coordinate system
1: Write the measured preset into the preset table.
The reference system is the machine coordinate
system (REF system).
