Linear Feed (G98/G94); Inverse-Time Feed (G93) (Milling Only); Revolutional Feedrate (G99/G95); Turning - Siemens SINUMERIK 808D Programming And Operating Manual

Note
If "F0" is programmed and the function "Fixed feedrates" is not activated in the block, then the alarm 14800 "Channel %1
Set %2 programmed path velocity is less than or equal to zero" is given off.
2.2.3

Linear feed (G98/G94)

On specifying G98 for turning/G94 for milling, the feed given after the address character F is executed in the mm/min,
inch/min or degree/min unit.
2.2.4

Inverse-time feed (G93) (milling only)

On specifying G93, the feed given after the address character F is executed in the 1/min unit. G93 is a modally effective G
function.
Example
N10 G93 G1 X100 F2 ;
i.e., the programmed path is traversed within half a minute.
2.2.5

Revolutional feedrate (G99/G95)

On entering G99 for turning/G95 for milling, the feed is executed in the mm/revolution unit or inch/revolution related to the
master spindle.
Note
All of the commands are modal. If the G feed command is switched between G98 and G99 for turning or among G93, G94,
and G95 for milling, the path feed must be reprogrammed. The feed can also be specified in degree/revolution for the
machining with rotary axes.
