Slowing Down In Corners

[spade117]

I thought there was a setting for making the cutter slow down in corners, but I was unable to find anything, and I can't seem to remember what setting it was.

 

Any help?

Oops, double post!

Machine Group Properties - Tool settings - Adjust feed on arc move - Min arc feed.

 

Is that what you are looking for?

Adjust feed on arc move?

That is in Machine Group Properties, Tool Settings tab.

to quote the help....

Adjust feed on arc move

Adjusts the current linear feed rate to fit arc geometry. The feed rate change occurs at the start point of the arc. The adjusted feed rate cannot exceed the linear feed rate and cannot fall below the minimum arc feed rate.

Yep...thank you both.

Do I need to change a setting in my post?...Nothing changed when I adjusted the setting, the toolpath still output the same feedrate...

Spade, you do have to regen for it to pick up that change

[mgsanchez]

hmm, I haven't had a problem with setting mine. I just make sure that I check the box.

Ive never used this function before so I have a quick question. When this slows cutters down in corners, does it only do internal corners or does it to internal and external?

[spade117]

Thanks JP.

A trick I like to do is turn on the slow corners, regen only the needed operation then lock that operation before turning the slow corners back off. That way I don't slow down the whole program.

internal and external.

Flycut, that sounds like a good trick. It should really be a switch in each operation, in my opinion.

That would be amazing!

Does any one use a formula for adjusting your feed in the corners?

 

Like: D-d/D X Straight IPM for I.D. corners and

 

D+d/D X Straight IPM for external corners where

 

D= corner diameter and d= cutter diameter.

 

I haven't used this formula myself just wondering if anyone does, or do you just wing it?

Yes, strabe, I do, but only in small holes. I find otherwise its not worth the time.
