Parameter Description Unit
Swivel mode
• axis-by-axis: Swivel coordinate system axis-by-axis
• Solid angle: Swivel via solid angle
• Proj. angle: Swiveling via projection angle
• Direct: Position rotary axes directly
Axis sequence
Sequence of the axes which are rotated around - (only for axis-by-axis swivel
mode)
XYZ or XZY or YXZ or YZX or ZXY or ZYX
X Axis angle Degrees
Y Axis angle Degrees
Z Axis angle
The sequence of the axes can be
interchanged as required using the
Select key.
Degrees
X1 New zero point of rotated surface mm
Y1 New zero point of rotated surface mm
Z1 New zero point of rotated surface mm
Note
Other additive transformations can be added to the offsets before (X0, Y0, Z0) or after (X1,
Y1, Z1) swiveling (see Section "Work offsets").
15.5 Approach/retraction
If you want to optimize approach/return for swiveling with the B axis, you can create a
special cycle that ignores the automatic approach/retraction strategy.
You can insert the approach/retraction cycle between any machining step program blocks,
but not within linked program blocks.
Sequence
The starting point for the approach/retraction cycle is the safety clearance approached after
the last machining operation.
If you want to perform a tool change, you can move the tool through a total of three positions
(P1 to P3) to the tool change point and through a maximum of three additional positions (P4
to P6) to the next starting point.
The 1st, 3rd, 4th and 6th positions move the linear axes, while the 2nd and 5th positions
move the rotary axes.
If no tool change is needed you can generate no more than six motion blocks.
