The new HEIDENHAIN standard cycles (beginning with Cycle 200) are written
like OEM cycles.
Application of OEM Cycles
Comment
Automatic compensation in the tool axis
Inquiry whether spindle on with M3 or M4
Error message, spindle
Inquiry whether tool is active
Error message, tool axis is missing
Inquiry whether machining direction is
negative
If not, set the constant to negative
Otherwise, set the constant to positive
Inquiry whether signs were already negated
Calculate Z end position
Inquiry whether 2nd safety clearance was
entered
If so, set a new Z end position
Calculate Z preparatory position
Calculate total hole depth
Transfer the feed rate for retraction
Inquiry whether feed rate for retraction was
entered
No: Feed rate for retraction = feed rate for
reaming
Negate sign-critical parameters
If sign was already reversed in the DEF
cycle, skip negation
9 – 9
