Unit 130 Contour Pocket on Point Pattern (FCL 3 Function)
With this working unit you can align on any pattern and rough out
pockets, which may contain islands, of any shape.

function) in the contour detail form. In this case you must always begin
with the deepest pocket.

 S : Spindle speed [rpm] or cutting speed [m/min or ipm]
 F: Feed rate for reciprocating plunge [mm/min], FU [mm/rev] or FZ
[mm/tooth] Enter 0 for perpendicular infeed
 F: Feed rate for plunging [mm/min], FU [mm/rev] or FZ [mm/tooth]
 F : Feed rate for plunging [mm/min] or FU [mm/rev] or FZ [mm/tooth]
 Depth: Milling depth.
 Plunging depth : Infeed per cut
 Allowance for side : Finishing allowance for the side
