Fixed Cycles
Chapter 25
25-3
The following sections describe the parameters that are used for the milling
fixed cycles. Milling fixed cycles typically include the control’s drilling,
tapping, and boring canned cycles.
Function
G73 mill control types.
G83.1 lathe control types.
Use this parameter to set the retraction amount for the intermittent high
speed drilling cycle. This parameter assigns a value “d” representing the
distance that the cutting tool retracts after each infeed amount in the
drilling operation. For this cycle, the tool cuts to the programmed depth in
steps. The tool feeds into the part a distance programmed with the Q-word
and then retracts out of the part the distance assigned with this parameter
“d.”

Notes
This is a global parameter; the value set here applies to all axes.
This parameter may also be changed on the control with the fixed-cycle
parameter table.
For Dual Processing controls, this is a per process parameter. The value set
in the parameters applies to all of the axes assigned to that process.
