Global Data Valid Everywhere; Global Data For Drilling Operations - HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING User Manual

Global data valid everywhere

U Setup clearance: Distance between tool tip and workpiece surface
for automated approach of the cycle start position in the tool axis
U 2nd set-up clearance: Position to which the TNC positions the tool
at the end of a machining step. The next machining position is
approached at this height in the machining plane
U F positioning: Feed rate at which the TNC traverses the tool within
a cycle
U
F retraction: Feed rate at which the TNC retracts the tool
The parameters are valid for all fixed cycles with numbers
greater than 2xx.

Global data for drilling operations

U
Retraction rate for chip breaking: Value by which the TNC
retracts the tool during chip breaking
U Dwell time at depth: Time in seconds that the tool remains at the
hole bottom
U Dwell time at top: Time in seconds that the tool remains at the
setup clearance
The parameters apply to the drilling, tapping and thread
milling cycles 200 to 209, 240, and 262 to 267.
