non modal feedrates

[TonyNanni@BNB]

Good morning

 

is there a way to make all feedrates non modal on an inverse time program? Using X3 MPMaster post and MMd.

 

Thanks

Tony,

when the post calculates out inverse time it makes it non-modal. The post and/or the MMD needs to setup that you get inverse for rotary motion.

Yes I got that part, The problem i'm having is the post out puts a F0.0 right in the middle of my program.

Those are very slow feedrates..

As an experiment, try doubling the feedrate on that

toolpath an see if you gert a value in that line..

 

also

check as see if your control will accept 5 digit feedrtates

for inverse time.(most new Fanucs will)

If so, change the post to output 5 places

Great

 

this is a new machine with a 18i-MB control and it does take 5plc feedrates. What is a typical feedrate, I'm new to inversetime. How do i stop it from outputting F0.0

change your post to output 5 place feedrates

when you do all those F9999.99's will also change

to something meaningfull

What toolpath is that? I remember the old 5 axis swarf has a fanning feedrate that defaults to zero. If you leave it at zero then it posts F0.

multiaxes parrallel to surface.

 

I changed the max inversetime feedrate to 10.0 so it won't post f0.0.
