Boring - CYCLE86

Function
With the "Boring" cycle, the tool approaches the programmed position in rapid traverse,
allowing for the retraction plane and safety clearance. It is then inserted into the workpiece at
the feedrate programmed under F until it reaches the programmed depth (Z1). There is an
oriented spindle stop with the SPOS command. After the dwell time has elapsed, the tool is
retracted either with or without lift of the tool.
For "lift off contour", the retraction distance D and the tool orientation angle α can either be
defined via machine data or in the parameter screen. If both parameters are pre-assigned
via machine data, they do not appear in the parameter screen.
NOTICE
The "Boring" cycle can be used if the spindle to be used for the boring operation is
technically able to go into position-controlled spindle operation.
