Icremental Contour Help

[ujmujm]

I have a slot with a floor that has a roller coaster type topography to it when viewed from the right side, I'm trying to chain a contour using that  geometry, there is a .400 radius that is part of the geometry, I'm using a .031 ball end mill and it won't follow the .400 radius, the tool starts at the first end point and proceeds to the second end point in a straight line instead of following any help would be appreciated.

Thanks

Cut Parameters / 3D contour.....

Also, set depth to incremental 0

Yep that's what I did, I'm in the process of creating new arcs to see if that helps.

[ujmujm]

The new arcs help but its cutting the arc in line segments and the radius is only .130 long so it cuts it in two line segments is there a way to tighten up that tolerance so it uses multiple line segments instead of two or even better swing a radius instead of line segments?

What is your tolerane for max depth varaince set too? Default is .005 not .001 like a  machinist would expect it to be. I go down to .0001 sometimes as I care about the quality of the part and not the amount of code needed to make a good quality part. 

[ujmujm]

exactly, I'm not worried about the amount of code the part needs to look like a jewel, I changed my max depth variance to .0001 didn't seem to make any improvement.

Time to share a file...we're all just going to be shooting in the dark otherwise

Here's  a jpeg of my verify surface the corner radii does not look good or the surface finish on side walls

Your part cuts looks excatly like that? You are not looking at the verify and calling that the gopshel are you? What is your filter tolerance? Might kick it down to .00005 and try .00005 on the max depth variance. 

I have to agree with JP might need a sample file so we can see what you are seeing. I just finished a over 400 operation part with about 30 million lines of code. I have 3D countours and 5 Axis and bunch of other things and it looks like new printed money.

My part looks better than the verification but I have a .002 profile tolerance and the .030 radii and they are not passing inspection. My filter is at the default setting of .001, I will change the settings to the ones you suggested.
