11.2.8 Profile programming syntax
The outside profile and the inside profiles or islands which are programmed must be defined by
simple geometrical elements such as straight lines or arcs.
The first definition block (where the external profile starts) and the last (where the last profile defined
ends) must be provided with the block label number. These label numbers will indicate the beginning
and end of the profile geometry definition for the profiles that make up the pocket.
The profile programming syntax must follow these rules:
• The first profile defining block must have a label number to indicate to the G66 canned cycle
the beginning of the geometry description.
• First, the outside pocket contour must be defined and, then, the contour of each island.
When a contour has more than one depth profile, the contours must be defined one by one
indicating, on each one, the plane profile and, then, its depth profile.
• The first profile defining block of the plane profile as well as that of the depth profile must contain
function G00 (indicative of the beginning of the profile).
Care must be taken to program G01, G02 or G03 in the block following the definition of the
beginning, as G00 is modal, thus preventing the CNC from interpreting the following blocks as
the beginnings of a new profile.
• The last profile defining block must have a label number to indicate to the G66 canned cycle the
end of the geometry description.
