The tool is moved in rapid traverse to the position to be centered,
allowing for the retraction plane and safety clearance. The tool is
inserted into the workpiece at programmed feedrate (F) until it
reaches Z1 or until the surface diameter is the correct size. When the
dwell time expires, the tool is retracted in rapid traverse to either the
retraction plane or the safety clearance depending on the setting in
parameter "Retraction position pattern". You will find parameter
"Retraction position pattern" in the program header or under "Settings"
in the "Miscellaneous" menu.
Press the "Drilling" and "Centering" softkeys.
