Touch Probe Cycles: Automatic Presetting | RIDGE CENTER PRESET (Cycle 409, DIN/ISO: G409)

Cycle parameters

Q321 Center in 1st axis? (absolute): Center of the
ridge in the reference axis of the working plane.
Input range -99999.9999 to 99999.9999
Q322 Center in 2nd axis? (absolute): Center of
the ridge in the minor axis of the working plane.
Input range -99999.9999 to 99999.9999
Q311 Ridge width? (incremental): Width of the
ridge, regardless of its position in the working
plane. Input range 0 to 99999.9999
Q272 Measuring axis (1=1st / 2=2nd)?: Axis in
the working plane in which the measurement is to
be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
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
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 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
536
The TNC writes to the preset table.
The TNC writes to the datum table. The
