not getting an smooth arc

[MSL]

Hi.

I'm trying to machine a simple 2d geometry but somehow can not get an smooth arc on my part. It looks like machining splines, but the geometry is arcs and lines. Not sure its a post issue or the machine its self. Attached is a picture of my control def. setting.

Our post is a modified mpmaster.

using Mastercam X5MU1

Thanks in advance.

Have you gone into the Filter settings and turned them on?

 

That will usually filter splines moves to arcs

Hi JParis,

My geometry made of arcs and lines. I don't have any splines there. I'm getting my G02,G03 with I,J codes. Which filter setting you are talking about?

Thanks.

Looks your using a Fadal, and judging from your description of the cut, there's a good possibility it's the machine going to fast around an arc. But first, do as JParis suggested, check the filter settings in your toolpath. It's below your linking perameters.

 

In my control def.I always keep my "Arc Breaks" set to "Don't Break Arcs' as a preference.

In the parameters of the toolpath there is a option called Arc Filter / Tolerance. Try changing your filter tolerance to what is seen there and let us know if that improves your part.

Can you post an example of the posted code? What toolpath are you using? How fast are you trying to feed through the arc?

+1 to Ben, if your code is a bunch of small arcs/lines, then the filter is the most likely cause.

If your code is nice big arcs & lines, your going to have to change feedrates (if their unusually fast) or (more likely) your machine needs some love.
