• PECK PERCENT—This field appears when either Decr Depth or Decr Chp Bkr
is selected for the Cycle Type. Peck Percent is a percent of the First Peck
Depth. For example, if the Peck Percent is set at 50, subsequent pecks will
equal a distance 50% smaller than the previous peck depth. A Minimum Peck
Depth must be set in order for the tool to reach Z Bottom.
• PECK COUNT—This read-only field appears when either Peck, Chip Breaker,
Decr Depth, or Decr Chp Bkr is selected for the Cycle Type. The number in the
Peck Count field represents the number of pecks to occur.
• PECK CLEARANCE—This field appears when either Peck, Chip Breaker, Decr
Depth, or Decr Chp Bkr is selected for the Cycle Type. Return at rapid feed
rate to this location above the last peck level. The default is 0.254 mm (0.010
in).
• TOOL DIAMETER—contains the tool diameter programmed in Tool Setup for
the current tool. This field is read-only and can only be edited in Tool Setup.
• SPEED—contains the spindle speed value programmed in Tool Setup. “CAL”
appears next to the value as programmed in Tool Setup. You can accept or
change this value. If you edit this field, “CAL” disappears.
• PLUNGE FEED—contains the feedrate between the Z START and Z BOTTOM
positions. “CAL” appears next to the value as calculated by the control. You
can accept or change this value. If you edit this field, “CAL” disappears.
• TIP COMPENSATION—This field appears when the tool is a Drill or a Center
Drill. Select YES or NO to indicate whether the tool tip is included as part of
the Z Bottom measurement. Z Bottom depth is automatically calculated for
the drill tip when YES is selected and is based on the drill tip angle
programmed in Tool Setup.
• RETURN LEVEL—identifies the level to which the tool should retract at the
end of the drill cycle. Select I Plane or R Plane.
• I PLANE—returns to the coordinate specified in the X/Z Start field.
• R PLANE—returns to the coordinate specified in the R Plane field.
Peck Depth Example:
First Peck Depth = 1.0 in.
R Plane = 0.1
Bottom of Hole (Z Bottom) = -3.0
Peck Percent = 80%
First Peck Depth = 1.0 in. cuts to depth of Z-0.90
Second Peck Depth = 0.8 in. cuts to depth of Z-1.7
Third Peck Depth = 0.64 in. cuts to depth of Z-2.34
Fourth Peck Depth = 0.512 in. cuts to depth of Z-2.852
Fifth Peck Depth = 0.4096 in. cuts to depth of Z-3.0, the specified
depth of the hole.
