L.. = overmetal on groove’s sides value expressed in mm.
NOTE: if only one of the two variables (F or L) is specified, the other variable will be assigned the same
value. If they are omitted both are considered null.
P.. = Depth of cut (it must always be more than 0, radial value expressed in mm.).The distance
between on cut and another is 0.2 mm.If omitted the machining is executed in one cut.
R.. = Specifies how many grooves (cycle repetition); if omitted , default value is 1.
S.. = Specifies the centre distance for groove repetition. It can be omitted if only one groove is
programmed (R=1). The value is expressed in mm and may be positive or negative.
