Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | BASIC ROTATION over two holes
(Cycle 401, DIN/ISO: G401)
Q305 Number in table? Enter the number of a
row from the preset table. The TNC enters the
specific entry in this row: Input range: 0 to 99999
Q305 = 0: The rotary axis is set to zero in row 0
of the preset table. An entry is therefore made in
the OFFSET column. (Example: An entry is made
in C_OFFS with tool axis Z). Additionally, all other
values (X, Y, Z, etc.) of the currently active preset
are saved in row 0 of the preset table. The preset
from row 0 is also activated.
Q305 > 0: The rotary axis is set to zero in the row
of the preset table specified here. An entry is
therefore made in the specific OFFSET column of
the preset table. (Example: An entry is made in
C_OFFS with tool axis Z).
Q305 depends on the following parameters:
Q337 = 0 and simultaneously
rotation is set in the row specified by Q305.
(Example: With tool axis Z, a basic rotation entry is
made in column SPC)
Q337 = 0 and simultaneously
Parameter Q305 is not effective
Q337 = 1 Parameter Q305 is effective as
described above
Q402 Basic rotation/alignment (0/1): Define
whether the TNC sets the measured misalignment
as basic rotation or aligns it via rotary table
rotation:
0: Set basic rotation: Here the TNC saves the
basic rotation (Example: With tool axis Z the TNC
uses the column SPC)
1: Perform rotary table rotation: An entry is made
into the specific Offset column of the preset
table (Example: With tool axis Z the TNC uses the
column C_Offs), the specific axis also rotates
Q337 Set to zero after alignment?: Define
whether the TNC sets the position display of the
specific rotary axis after alignment to 0:
0: After alignment the position display is not set to
0
1: After alignment the position display is set to 0 if
you previously defined Q402=1
