TECHNOLOGICAL FUNCTIONS
Machining feedrate (F)
(SOFT V02.0X)
56
When rotary axes are involved in the interpolations, the feedrate of
these axes is calculated so the beginning and the end of their
movement coincides with the beginning and the end of the main axes.
If the feedrate calculated for the rotary axis is greater than the
maximum allowed, the CNC will adapt the programmed "F" so the
rotary axis can turn at its maximum speed.
Feedrate override
The programmed feedrate "F" may be varied between 0% and 200%
using the selector switch on the CNC's operator panel or it may be
selected by program or by PLC. However, the maximum override is
limited by the machine manufacturer [G.M.P. "MAXOVR"].
When making movements in G00 (rapid traverse), the feedrate
override percentage will be fixed at 100% or it may be varied between
0% and 100% depending on how the machine manufacturer has set
[G.M.P. "RAPIDOVR"].
When carrying out threading operations, the feedrate percentage will
be fixed at 100% of the programmed feedrate.
