the rotation angle values stored in the system variables must at least correspond approximately
to the mechanically set rotation angles.
Note
Tool orientation
It is not possible for the control to check whether the rotation angles calculated by means of the
frame orientation are settable on the machine.
If the rotary axes of the toolholder are arranged such that the tool orientation calculated by
means of the frame orientation cannot be reached, then an alarm is output.
The combination of tool precision compensation and the functions for tool length offset on
movable toolholders is not permissible. If both functions are called simultaneously, an error
message is issued.
The TOFRAME function allows a frame to be defined on the basis of the direction of orientation
of the selected toolholder. For more information please refer to chapter "Frames".
When orientation transformation is active (3, 4 or 5-axis transformation), it is possible to select
a toolholder with an orientation deviating from the zero position without causing output of an
alarm.
Transfer parameter from standard and measuring cycles
For the transfer parameter of standard and measuring cycles, the following defined value
ranges apply.
For angular value, the value range is defined as follows:
● Rotation around 1st geometry axis: -180 degrees to +180 degrees
● Rotation around 2nd geometry axis: -90 degrees to +90 degrees
● Rotation around 3rd geometry axis: -180 degrees to +180 degrees
Refer to Chapter Frames, "Programmable rotation (ROT, AROT, RPL)".
Note
When transferring angular values to a standard or measuring cycle, the following should be
carefully observed:
Values less than the calculation resolution of the NC should be rounded-off to zero!
The calculation resolution of the NC for angular positions is defined in the machine data:
MD10210 $MN_INT_INCR_PER_DEG
3.13.10 Modifying the orientable tool carrier according to the machine measurement
(CORRTC)
Measured kinematic chain elements of a tool carrier can be written to special correction
elements with the CORRTC function.
