Template 4: Deep Hole Drill Cycle, Chip Break
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 drilling operation.
X 503 DEPTH OF HOLE The location to which the tool drills into the part. If the cycle uses adaptive depth, this
position needs to be beyond the adaptive depth increment.
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.
Q 505 INFEED AMOUNT This defines the infeed amount for each step into the hole
X,Y 506, 507 RETURN POSITION X, Y The location where the controls starts and stops a cycle.
F 508 FEEDRATE The feedrate for drilling/boring operations. This is also the maximum feedrate for
operations that use adaptive depth.
P 509 AMOUNT OF DWELL The amount of time the axis pauses before it retracts from the hole; measured in
seconds.
X 510 TOOL CHANGE POSITION The location where the controls starts and stops a cycle.
E 511 ADAPTIVE FEED MINIMUM This is the minimum feedrate at which the control performs an adaptive feed operation.
The control will try to maintain this minimum feedrate, even if it means increasing the
adaptive feed torque percent.
Q 512 ADAPTIVE FEED TORQUE % This is the amount of the selected servo’s continuous rated torque as entered in AMP by
your system installer. Valid ranges are from 1 to 150% of the servo’s rated torque.
Refer to your system installer’s documentation for details on the rated torque of the
servos in your system.
Important: The torque amount applied by the servo is not the cutting force. It is the
torque applied by the servo to the axis. You must calculate the equivalent cutting force
based on your machine dynamics (motor rated torque, lead screw pitch, gearing, tool
dimensions, etc...).
I 513 HARD STOP SENSE ZONE Once it reaches this location, the control knows to expect a hard stop before reaching
the hole bottom.
I 514 ADAPTIVE DEPTH INCREMENT The amount of distance between the surface of the part and the depth of hole.
M 515 M03/M04 The M--code used to turn the spindle clockwise or counter-clockwise.
S 516 SPINDLE SPEED The speed of the spindle. Measured in revolutions per minute.
Required entry Optional entry
d - This value is written into the cycle. It is .01 inches (.254 mm).
