Swiveling plane/tool (CYCLE800)

The CYCLE800 swivel cycle is used to swivel to any surface in order to either machine or
measure it. In this cycle, the active workpiece zeros and the work offsets are converted to
the inclined surface taking into account the kinematic chain of the machine by calling the
appropriate NC functions - and rotary axes (optionally) are positioned.
Swiveling can be realized:
● axis by axis
● via solid angle
● via projection angle
● directly
Before the rotary axes are positioned, the linear axes can be retracted if desired.
Swiveling always means three geometry axes.
In the basic version, the following functions
● 3 + 2 axes, inclined machining and
● toolholder with orientation capability
are available.
Setting/aligning tools for a G code program
The swivel function also includes the "Setting tool" and "Aligning milling tool" functions.
Contrary to swiveling, when setting and aligning, the coordinate system (WCS) is not rotated
at the same time.
Prerequisites before calling the swivel cycle
A tool (tool cutting edge D > 0) and the work offset (WO), with which the workpiece was
scratched or measured, must be programmed before the swivel cycle is first called in the
main program.
Example:
N1 T1D1
N2 M6
N3 G17 G54
N4 CYCLE800(1,"",0,57,0,0,0,0,0,0,0,0,0,1,0,1))
N5 WORKPIECE(,,,,"BOX",0,0,50,0,0,0,100,100)
For machines where swivel is set-up, each main program with a swivel should start in the
basic setting of the machine.
