CYCLE800 is the standard swivel cycle in Siemens Sinumerik controllers, transforming the active workpiece coordinate system to any spatial plane for 3+2 multi-sided milling and drilling.
CYCLE800 converts spatial rotation angles into precise machine kinematic axis coordinates (A, B, C), aligning the tool vector perpendicular to the selected inclined feature.
Standard Operating Protocol
CYCLE800(...): Converts spatial angles into machine kinematic coordinates, orienting the tool perpendicular to the angled face.
CYCLE800(): Empty call cancels the swivel plane and resets the coordinate system to Z-top.
TRAORI Integration: Works alongside TRAORI for seamless transitions between 3+2 indexing and simultaneous 5-axis continuous milling.
Frequently Asked Questions
How does CYCLE800 calculate swivel coordinates on different CNC machine kinematics?
The Siemens controller reads the machine kinematic chain from system variables, automatically computing motor positions for any head or table configuration.
What happens if CYCLE800 is not cancelled at the end of an angled operation?
Subsequent toolpaths will execute in the angled coordinate system, resulting in severe machining location errors.
