Roughing Cycle Parameters
Chapter 28
28-3
Axis Parameter
Number
All [22]
Range
0 to 255%
Notes
This parameter is a global parameter. The value set here applies to all axes
and processes.
Function
This parameter applies only to the O.D and I.D Roughing Cycle and the
Rough Facing cycle. This parameter is used to force the control to make a
finishing pass that cuts parallel to the workpiece’s exact contour. Typically
this finishing pass is defined with the I and/or K words in the calling block.
This finishing pass is made at the same feedrate as the rough contouring
routine used.
Axis Parameter
Number
All [23]
Important: This parameter is not related to the finishing cut made by the
O.D. and I.D. finishing cycle. If an amount of material is to be left on the
workpiece to be removed later by a O.D and I.D. finishing cycle, the
finishing pass discussed here will not affect this material. This parameter
is related to the finishing pass that is made immediately after the basic
contour of the part has been roughed out with a O.D. and I.D. Roughing
Cycle or a Rough Facing Routine.
When this parameter is set: And if: Then:
TRUE an I and/or K parameter is programmed in the calling block,
then the amount of material removed on this last pass is equal
to the I and/or K amounts
the control always cuts a finishing pass as the
last pass of the O.D and I.D Roughing Cycle
or the Rough Facing cycle
no I and/or K is programmed in the calling block, then the
finishing pass is made along the workpiece contour (removing
whatever material is left by the roughing operation) + or -- the
amount programmed for an O.D. and I.D. finishing cycle
(programmed with a U and/or W if any)
FALSE the I and/or K parameters are programmed in the calling block this is the only time that a finishing pass is
made during these cycles
no I and/or K parameters are programmed no finishing pass is made
