Tool life estimator [IMPLEMENTED]

Not sure what would go into this, or how it would best be implemented, but I think a neat feature for roughing, specifically HSM would be to add something that would estimate tool life. Even if it were purely comparative, for instance comparing the effects of 8% engagement to 15% engagement. How will that change effect tool wear, and is it worth the increase in MRR? etc.

Good idea.
......
Right now I am working on a long delayed improved material database.
At the same time I will add necessary provisiont to later include tool life estimation.

Thank you.

Hello,
I made the announcement on the front page.
It has been added in version 0.600
It seems to give a pretty good idea as far as tool life goes in steels.

Of course it does not really work very well when machining abrasive materials.
Also if you decrease cutting speed alot it will give you incredible tool life.
Which may be not true at all.
I should probably limit displayed values by 10% min and 500% max.
To keep people from getting confused.

I am thinking to further improve it as i get some more feedback from you guys.

Feedback is welcome.

It looks like you caught one end of this already, as it doesn't occur with the feed slider, but sliding the spindle speed override to zero causes a crash (i'm guessing because the tool life estimation is attempting to represent infinity as a number..)

Looks useful at a quick glance, will report more once i've actually had a chance to play with it some.

Oh slap!
How ironic.
Its the good old devision by zero error!

Ok it does not realy happen in normal use. I will fix it next time.

Thanks for letting me know!

Question: Is the tool life estimated by unit time, cut inches, or volumetric removal? I think most useful would be by volumetric removal.

Thanks.

Tool life right now is estimated by time.
But the time it gives is percentage based on a benchmark.

With time you can estimate how long the tool will actually last.
IE. You know that with everything default you get 1 hour of tool life at 100% tool life.

Then when you see it showing 200% you know that the tool is going to last for 2 hours.

I will add user-defined timing later, so it can show how many minutes the tool is expected to live.
