Mill facing

[frostfritt]

I think there is a problem with dynamic facing. If your mill has a cornerradius it does not clean up all surface. There will be spikes in the corner of the toolpath. Most chipmil have a radius.

What do you think of making dynamic facing also handle corner radius mills?

You can set the step over to a lower value

manually.

I have ran into the same thing. Doesn't matter how small you make your stepover.

[MotorCityMinion]

Hmm, I would think that 70% cutter dia. less 2x the corner radius would be adequate for full cleanup.

[Leigh @ Kodiak]

I will try to find the time ad post a screenshot tomorrow showing where the problem has occurred for me. It's not exactly the stepover that causes an are to not fully clean up, but rather any spot where the tool works towards from either side.

The exit move(refered to as 'micro lift' earlier in this thread) at the end of a dynamic face toolapth is hardcoded, you do not have to enable it. You will find this in X4.

Going all the way back to the original post. Are you using the facng toolpath or the facing optionin the 2D Pocket toolpath?

WOW......haven't looked back to this thread for a while........I will read thru it and get back to you Davis........Prolly in the AM.....

What ever his using, he have a problem with facing in the first post. If you reading more you will se he is rekomended to trim toolpath and even to drow his own. Right recomendation will be dynamic opt if only that problem with cornerradius was solved.

 

70% stepover look good at screen but bad in the rality with all the cornerspikes and the long uncut ribb att the mid in my rektangular part. I tryed dia 20mm 0.8mm rad today.

 

So now please get this fixed for the next Mu1 and we all can facing dia, rectangular and what ever in all our days.

Here is a screen shot that shows a lack of control on how two regions meet. This causes problems with bullnose tools leaving excess stock.

Here are some screen shots..........Its a horizontal MILLING machine and the screen shot is from the TOP view.

 

The first level in faceing the first level of round stock.......see the start and end are cutting air.......

 

 

 

Here is a shot of the last level.....by the end of the material......very little air cuts......

 

 

 

Is there a way to get the first cut closer to the material......like a step down where the material gets wider.

Use Trim on your Facing toolpath, or create a solid cylinder to use as stock and use Rest Rough. These are the two easiest ways that come to mind.

[Ocean Lacky™]

Here's an example using the Trim function

Thanks Ocean.....Thats what I am looking for.....I would like to try it......BUT....where is trim on the facing toolpath??????? Could you send me the file so I could interrogate it?

[Rick Henrickson 65]

how about hsm core rough with boundary should be just what you are looking for

[Jayson Kramer]

How about just doing the pocket facing like I showed earlier and use taper like shown here.

this is you 4" dia and a reference of 6"

Columbo......You have Mail
