Hi All,

I'm looking to be educated some on using the Newfangled Circle Cutting Wizard. When I attempt to use it, I keep getting a small movement out side the circle which creates a small arc in my work piece. I'm trying to cut an inside circle, so that creates a defect in the part.
I am enclosing the code generated by the wizard and a screen shot showing the little "dogleg" that it makes.

Any help or suggestions would be greatly appreciated.

I posted your code in NCPlot and it looks fine. I would bet that it is how and when the cutter comp is applied that you are seeing your gouge. I would re run the wizard and not use cutter comp. ( G41 ) Using cutter comp is not for the novice and can even bite the seasond veteran on occasion.

Scott,

Thank you for the quick reply, I did as you suggested and it cut perfectly.

I suppose my follow up question would be why the wizard would put in the cutter comp as a default? The tool number (4) is not populated in the tool table, so I don't know it that has an effect of not, since the only data it has about the tool is what's typed in when setting up the wizard? That data was 2 flute .1875" carbide endmill.

Hi Terry
Glad you got it !
I do not use the wizards very much and did not buy the New-Fangled suite. So I am unfamiliar with them. But cutter comp can be very useful , but also very troublesome for the novice. I would think that "Wizards" would be used more often by a novice so I too would wonder why it is the default ??? I do not know if New Fangled has any kind of support but I think it would be a good question to ask them.

Whoops forgot to add...The code you posted has the offset data included ( P0.0625 ) If you give it a P number it will use that instead of the tool table data.

Thanks again Scott,

Now that I know it wasn't something that I did (at least not intentionally), I'll go over to the Mach 3 forum and try to run it down.

From what I can tell almost all of the wizards try to use G41/G42 with similar results. I have never been able to figure how to turn it off (in the wizards).

I'm with you, I see them in most that I've tried.

One interesting point, after I did the deletions that I mentioned earlier, I noticed I was using an older version of the wizards (2.72 vs2.86) because I reloaded the wrong version by mistake after I did the Series III upgrade. After fixing that, I still see those codes in the output of the wizard, but I cut a bunch of 1.3" holes this afternoon, and they were fine, even with the G 41's? So I guess they are OK for the simple stuff I was doing.

I was having this exact same issue. Upgrading to 2.86 seems to have helped. I think it must have been a bug.
