Problem- Engagement of Inches Per Revolution

[chipsahoy]

Hi all

Seem to encountered a problem.. Recently re loaded my PCM Parameters..
Everything is up and running.. What I am noticing is that im not engaged when I run Inches Per Revolution.. On the "check screen" it shows running say .006 IPM, but I can over ride the feed and that shows in FPM.. Bottom line one knows when they are engaged properly because you can override the spindle and the feed will slow down or speed up in relation..

I appreciate you comments..

Do you mean if you turn the spindle override down to 0, the axes keep feeding? I was confused by "I can over ride the feed and that shows in FPM".

AFAIK, the ACT.F is always shown in inches or MM / minute.

[chipsahoy]

Yes it keeps on feeding.. It should slow down or speed up when you adjust the spindle..Also the Feed switch should have effect when in IPR mode.

What do you think ??

[dcoupar]

The feedrate override switch should work in either IPM or IPR. If you turn it down to 0, it should stop the feed.

If you're feeding in IPM (G98), the spindle speed override won't have any effect on the IPM.

If you're feeding in IPR (G99), the spindle speed override should vary the IPM accordingly.

What model control is it?

If this is no G96 you may have missed a 900 or 9000 option parameter entry.

What parameter is at start up that makes sure its in IPR..

Are there options??

Also what shouild it be??

Cheers !!

[chipsahoy]

What does 9130 Parameter do.. ?? I do see a difference from my factory settings

Chips

[Al_The_Man]

Well your G96 is enabled according to your parameters.
I always thought G97 was constant surface speed cancel?
Don't you want G99? feed per rev?
Al.

[chipsahoy]

Al

Yes I do want G99 "FEED PER REVOLUTION"


Please explain what I have wrong??

What must I change !!

Did you see my post on the program example..??

Chips !!

[chipsahoy]

Mistake on the last entry..

Im trying to get "Inches per revolution".. IPR

example

.006 chip per rev

[dcoupar]

Your program looks fine.

G99 (FEED PER REVOLUTION) is active.
G97 (CONSTANT SURFACE SPEED CANCEL) is active

F0.006 should feed at 0.006 IPR X 1000 RPM = 6.0 IPM with overides at 100%.

What happens in this program if you turn spindle speed override down to 0%? Does X still feed to -0.0625?

I don't have an option list for the 10T, so I can't tell you what 9130 does.
