Template 13: Boring Cycle, Dwell/Feed Out
Letter Paramacro Label Description
G 500 G90/91 G-codes G90 or G91 for absolute or incremental modes. At this time only absolute
mode, G90, is available.
X,Y 501, 502 HOLE POSITION X, Y The location to which the tool moves before it begins a boring operation.
X 503 DEPTH OF HOLE The location to which the tool bores into the part.
R 504 CLEAR POSITION The location that the tool retracts to after an operation. It is completely free of the
part. This also known as the R plane.
X,Y 505, 506 RETURN POSITION X, Y The location where the controls starts and stops a cycle.
F 507 FEEDRATE The feedrate for drilling/boring operations, and all moves represented by the solid
lines in the QuickView screens. This is also the maximum feedrate for operations
that use adaptive depth.
P 508 AMOUNT OF DWELL The amount of time the axis pauses before it retracts from the hole; measured in
seconds.
X 509 TOOL CHANGE POSITION The location the control moves to so that a tool change may be performed.
I 510 HARD STOP SENSE ZONE Once it reaches this location, the control knows to expect a hard stop before
reaching the hole bottom.
I 511 ADAPTIVE DEPTH
INCREMENT The amount of distance that the control will increment the tool into the part during an
adaptive depth operation.
M 512 M03/M04 The M--code used to turn the spindle clockwise or counter-clockwise.
S 513 SPINDLE SPEED The speed of the spindle. Measured in revolutions per minute.
