Drilling Operation
These fields appear for performing drilling operations based on the Cycle Type selection:
• DWELL TIME (SEC)—specifies the time in seconds the Z axis dwells after
the cycle reaches Z Bottom and before retracting at Rapid. This field appears
when either Dwell or Center Drill is selected for the Cycle Type.
• PECK DEPTH—defines the maximum depth to be cut in one pass. This field
appears when either Peck, Chip Breaker, Decreasing Depth, or Decreasing
Chip Breaker is selected for the Cycle Type.
• FINAL PECK DEPTH—defines the maximum depth to be cut in the final
pass. This field appears when either Decreasing Depth or Decreasing Chip
Breaker is selected for the Cycle Type.
• PECK PERCENT—defines the 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. This field appears when either
Decreasing Depth or Decreasing Chip Breaker is selected for the Cycle Type.
• PECK COUNT—displays the number of pecks that will occur. This read-only
field appears when either Peck, Chip Breaker, Decreasing Depth, or
Decreasing Chip Breaker is selected for the Cycle Type.
• PECK CLEARANCE—defines the location above the last peck level for
returning at rapid feed rate. The default is 0.254 mm (0.010 in). This field
appears when either Peck, Chip Breaker, Decreasing Depth, or Decreasing
Chip Breaker is selected for the Cycle Type.
Tapping Operation
This field appears for performing tapping operations when the tool is a Live Tap:
• TAP CYCLE—accesses Standard or Rigid Tap cycle selections. This field
appears when the tool is a Live Tap.
• Standard cuts threads inside a hole.
• Rigid taps the same hole multiple times, maintaining the tool’s
orientation with previously cut threads.
When performing rigid tapping, the hole must be longer than the
tap. To accomplish this, program the preceding drill operation to be
longer than the tap operation.
Here are some suggestions when Tapping:
• Use a floating tap holder to prevent the tap from breaking when
the spindle reverses direction.
• When tapping hard materials, use tapping fluid (not coolant) as a
lubrication.
• When tapping hard materials, use a tap drill one size larger than
normal because less thread engagement requires less torque.
• The recommended Z Start is 0.200 minimum from the part
surface to compensate for floating tap holder characteristics.
