Touch Probe Cycles: Automatic Presetting | PRESET CIRCLE CENTER (Cycle 416, DIN/ISO: G416)

Cycle parameters

Q273 Center in 1st axis (nom. value)? (absolute):
Bolt hole circle center (nominal value) in the
reference axis of the working plane. Input range
-99999.9999 to 99999.9999
Q274 Center in 2nd axis (nom. value)?
(absolute): Bolt hole circle center (nominal value)
in the minor axis of the working plane. Input range
-99999.9999 to 99999.9999
Q262 Nominal diameter?: Enter the approximate
bolt hole circle diameter. The smaller the hole
diameter, the more exact the nominal diameter
must be. Input range -0 to 99999.9999
Q291 Polar coord. angle of 1st hole? (absolute):
Polar coordinate angle of the first hole center
in the working plane. Input range -360.0000 to
360.0000
Q292 Polar coord. angle of 2nd hole? (absolute):
Polar coordinate angle of the second hole center
in the working plane. Input range -360.0000 to
360.0000
Q292 Polar coord. angle of 3rd hole? (absolute):
Polar coordinate angle of the third hole center
in the working plane. Input range -360.0000 to
360.0000
Q261 Measuring height in probe axis? (absolute):
Coordinate of the ball tip center (= touch point) in
the touch probe axis in which the measurement
is to be made. Input range -99999.9999 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 of the center point; input
range 0 to 9999. The TNC writes the entry to the
preset table or datum table depending on Q303:
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
Q331 New preset in reference axis? (absolute):
Coordinate in the reference axis at which the
TNC should set the bolt hole circle center.
Default setting = 0. Input range -99999.9999 to
99999.9999
