Circular Interpolation (G02, G03) - Siemens Sinumerik 840D sl Programming Manual

Feed F for path axes
The feedrate is specified under the address F. Depending on the default setting in the
machine data, the units of measurement specified with the G commands (G93, G94, G95)
are either in mm or inch.
One F value can be programmed per NC block. The unit of feedrate is defined over one of
the mentioned G commands. The feed F acts only on path axes and remains active until a
new feed value is programmed. Separators are permitted after address F.
Note
An alarm is triggered while executing a G01 block if no feed was programmed in a block with
G01 or in the previous blocks.
The end point can be specified either as absolute or as incremental. Details are available in
Chapter "Absolute/incremental dimensioning".
