Swivel in the "+" (plus) direction
● Rotary axis B moves to +10 degrees in the
positive direction.
● Rotary axis C moves to 270 degrees.
Swivel in the "-" (minus) direction
● Rotary axis B moves to -10 degrees in
the negative direction.
● Rotary axis C moves to 90 degrees
(rotation around X!).
The two "Minus" or "Plus" direction settings enable a workpiece to be machined with swiveled
planes. The two solutions calculated by the NC differ by 180 degrees (see rotary axis C).
Example 2: Horizontal machine - no rotary axis rotates in the basic position around the tool axis
● Machine kinematics with swivel table.
● 1st rotary axis (A) in the swivel table rotates around machine axis X.
– Angular range, rotary axis 1 (A) from -90 degrees to +90 degrees.
● 2nd rotary axis (B) in the swivel table rotates around machine axis Y.
– Angular range, rotary axis 2 (B) from 0 degrees to 360 degrees (modulo 360).
● Machine manufacturer has set the direction reference to rotary axis 1 (A) when he
commissioned the swivel function.
● In the swivel cycle, a rotation (ZYX) is programmed through Y=30 degrees and X=10
degrees.
