3.16 Swiveling – CYCLE800 (SW 6.2 and higher)
The Swiveling cycle is not an option, but is available for the
HMI with SW 06.02 and NC SW 6.3 (CCU SW 4.3) and
higher.
The functions
• 3/2 axes inclined machining and
• orientatable toolholder
are available in the basic version.

Function
The cycle is used during milling to swivel on any type of
surface so that it can be machined and/or measured.
By calling the appropriate NC functions, the cycle
converts the active workpiece zeroes and tool offsets to
refer to the inclined surface, taking account of the
kinematic chain on the machine, and positions the
rotary axes (optional).
Swiveling can be implemented either axially, as a
projection angle or as a solid angle.
Before the rotary axes are positioned, the linear axes
can be retracted if desired.
Machine kinematics
1. Swivel-mounted toolholder (swivel head)
2. Swivel-mounted workholder (swivel table)
3. Mixed kinematics from 1 and 2
Important
The zero offset (ZO) with which the workpiece was scratched
or measured must be programmed before the swivel cycle is first
called in the main program. This zero offset is converted to the
appropriate machining plane in the swivel cycle. The ZO value
remains unchanged. Translational and rotational components are
saved in system frames (swivel frame), tool reference
(PARTFRAME), toolholder (TOOLFRAME) and workpiece reference
(WPFRAME) (see HMI à parameters, active ZO).
