Additional parameters on the contour detail form:
8 Depth: Separately definable depths for each subcontour (FCL 2
function)
Globally effective parameters on the global data detail form:
8 Set-up clearance
8 2nd set-up clearance
8 Overlap factor
8 Retraction feed rate
8 Climb milling, or
8 Up-cut milling
„ As a rule, always start the list of subcontours with the
deepest pocket!
„
If the contour is defined as an island, the TNC interprets the
entered depth as the island height. The entered value
(without an algebraic sign) then refers to the workpiece top
surface!
„ If the depth is entered as 0, then for pockets the depth
defined in the overview form is effective. Islands then rise
up to the workpiece top surface!
