Milling Fixed Cycles

Chapter 26

26-38

The system installer determines many parameter for the milling fixed
cycles in AMP. The following 3 parameters are set in AMP but may be
overridden by the operator using the Milling Cycle Parameter screen.
When changed through this screen, the new values remain in effect until
they are manually changed or AMP is downloaded with new values.

G73 Deep Hole Peck Drilling Cycle retract amount - This parameter
determines the value of “d”. “d” for this cycle is the distance above the
last infeed step that the control retracts the tool from the part, normally
to clear chips. See the section on G73 Deep Hole Peck Drilling cycle
for details on this cycle’s operation.

Clearance Amount for Cycles - This parameter also determines the
value of “d”. The amount “d” for this cycle is the distance between the
end of the tool and the plane of the uncut part. See the section on G83
Deep Hole Drilling for details on this cycles operation.

G76 / G87 Fine/Back Boring Cycles Shift Axis - This parameter
determines the axis that the shift amount programmed with “Q” will be
on. Note that a shift in either axis, in either direction (positive or
negative) for the currently active plane can be selected.This parameter is
ignored if the shift direction is programmed in the block using I--, J--, or
K--words.
