CAUTION
For inch inputs, an F command with no decimal point
is assumed to have a decimal point in between its
second and third places as counted from the lowest
place. Note that the settings of RFA = 0 and RFE = 0
can produce the following example.
Example) When F1234 is issued, F12.34 (inch/min)
is assumed, resulting in F12.00 (inch/min).
Example
Z-axis feedrate 1000 mm/min
Spindle speed 1000 min
