TECHNOLOGICAL FUNCTIONS
5.1 Machining feedrate (F)
The machining feedrate may be selected by programmed using the
"F" code which remains active until another value is programmed. The
programming units depend on the active work mode (G93, G94 or
G95) and the type of axis being moved (linear or rotary).
It is possible to program using parameters or arithmetic expressions.
Operation
The programmed "F" is effective in movements of linear (G01) or
circular interpolations (G02, G03). Movements in G00 (rapid traverse)
are executed at the feedrate set by machine manufacturer [A.M.P.
"G00FEED"] regardless of the programmed "F" value.
The feedrate is measured along the tool path, either along the straight
line (linear interpolations) or along the tangent of the indicated arc
(circular interpolations).
When only the main axes (X-Y-Z) are involved in the interpolation, the
relationship between the components of the feedrate on each axis and
the programmed "F" is the same as between the displacement of each
axis and the resulting programmed displacement.
