Machining cycles
HEIDENHAIN recommends programming a fixed cycle as follows:
Insert the tool
Define the cutting data
Position the tool in front of the working area
Define the safety clearance
Cycle call
Retract the tool
Move to the tool change position
NOTICE
Danger of collision!
Some parameters are non-volatile, e.g. special feed rates or
approach and departure variants
With missing program steps (parameters are not redefined)
the control uses the last programmed values for all subsequent
machining operations. This may cause undesired constellations,
e.g. feed rate for finishing with recessing cycles.
Always use the recommended program structure
Define all relevant parameters for each machining operation
