1) Positioning the rotary axes in a separate block
Proceed as follows if you want to position the rotary axes in a separate
positioning block (option STAY selected):
 Select any PLANE function, and define automatic positioning with the
STAY
option. During program execution the TNC calculates the
position values of the rotary axes present on the machine, and
stores them in the system parameters Q120 (A axis), Q121 (B axis)
and Q122 (C axis)
 Define the positioning block with the angular values calculated by
the TNC
NC example blocks: Position a machine with a rotary table C and a
tilting table A to a spatial angle of B+45°.
Danger of collision!
Pre-position the tool to a position where there is no danger
of collision with the workpiece (clamping devices) during
positioning.
