Swiveling - Siemens SINUMERIK 840D sl Operating Manual

Machining on an inclined surface
You can define inclined surfaces in a swivel mask.
You can enter the rotation of the planes around the geometry axes (X, Y, Z) of the tool
coordinate system as described in the workpiece drawing. The rotation of the Work in the
program is then automatically converted to a rotation for the relevant B and C axis of the
machine during machining.
The swivel axes are always rotated to place the tool axis perpendicular to the machining axis
for machining. During machining, the rotary axes are stationary.
The coordinate system is adapted to the surface to be machined irrespective of the required
rotary axis positions.

Swiveling

General sequence
● Swivel the coordinate system into the plane to be machined via the swivel screen.
● Machining with the setting "Face B".
● If another machining type follows, swiveling is automatically deselected.
The swiveled coordinates are maintained in the reset state and after Power On. So you can
still move out of an inclined hole, for example, with retraction in the +Z direction.
Swiveling is executed one axis at a time. In the case of axis-by-axis swiveling, the coordinate
system is rotated around each axis in turn, with each rotation starting from the previous rotation.
The axis sequence can be freely selected.

Machine manufacturer
Please refer to the machine manufacturer's specifications.
1. The "Spigot Res. Mat." input window opens if you press the "Various"
softkey.
2. Press the "Swivel plane" softkey.
3. Press the "Initial position" softkey if you wish to reestablish the basic
setting, i.e. you wish to set the values back to 0.
This is done, for example, to swivel the coordinate system back to its
original orientation.
