Re: [CAD_CAM_EDM_DRO] Re: Question about angular and linear feedrates

Dan

does TurboCNC support the G93 Inverse-time-feed mode ?
it lets you tell the control how long it should take to run each block

I remember that G93 feed mode was recomended to us for doing mixed
linear/rotary axis work

the confusing part is that no one documents it in quite the same way
for instance both of these discribe basicly the same formula :-)

EMC
In inverse time feed rate mode, an F word means the move should be completed
in [one divided by the F number] minutes. For example, if the F number is
2.0, the move should be completed in half a minute.

Haas
To calculate the time for a stroke, divide the inverse-time-feed rate into
60. For example, an inverse-time-feed rate of F1000 dictates that the
commanded motion of that line will take 0.06 seconds.

so this move would take about 180 seconds
