With tool axis X:
n
Universal swivel head as of NC software 280 476-01:
Axis sequence B fixed; A variable; B fixed; C variable
MP7500 "Tilted working plane"
Format: %xxxxxxxx
Input: Bit 0 – Switch-on "tilted working plane" function
0: Off
1: On
Bit 1 –
0: Angles correspond to the position of the tilting axes of the
head/table
1: Angles correspond to the spatial angle (the TNC calculates
the position of the tilted axes of the head/table)
Bit 2 –
0: The tilting axes are not positioned with Cycle 19
1: The tilting axes are positioned with Cycle 19
Bit 3 –
0: The current tilting-axis position is taken into account with
respect to the machine datum
1: The 0° position is assumed for the first tilting axis
Bit 4 –
0: Compensate mechanical offset during exchange of the
spindle head when calling M128, M114 or "tilted working
plane"
1: Compensate mechanical offset during PLC datum shift
Bit 5 –
0: The current tilting-axis position is taken into account with
respect to the machine datum
1: The tilting-axis position that was entered with the 3-D ROT
soft key applies
Bit 6 –
0: Spatial angle C is realized through a rotation of the coordinate
system
1: Spatial angle C is realized through a rotation of the table
Bit 7 –
0: The current tilting-axis position is taken into account with
respect to the machine datum
1: The active tilting-axis position is
a) derived from the tilting angles in the 3-D ROT window if
manual tilting is active.
b) derived from the reference coordinates of the rotary axes if
tilting is inactive.
Bit 8 –
0: The tilting axis positioning is considered depending on bit 3,
bit 5 and bit 7
1: If manual tilting is active, the datum to be set for the principal
axes X, Y and Z is recalculated back to the home position of the
tilting element
