Roughing Cycle Parameters

28-4
Range
Selection Result
(a) True
(b) False
Notes
This parameter is a global parameter. The value set here applies to all axes
and processes.
Function
This parameter applies to the O.D and I.D Roughing Cycle, and the Rough
Facing cycle (G71 and G72 lathe G-code system C). Use this parameter to
establish the least amount of material that can be removed in a single pass.
Typically the programmer determines the depth of each pass in these
cycles by programming a “D” word in the calling block. If the depth of
pass generated by this D word is smaller than the value assigned with this
parameter, the control will increase the depth of cut up to the value
assigned here. If the last finishing pass is calculated to be smaller than this
value, the control will decrease prior roughing cuts to allow enough
material to remain for the final pass to be as large as the value of
this parameter.
