Accuracy of Verify or Vericut?

 

I am milling some small pockets around a cylinder using axis substitution. I do quite a bit of this type of thing and usually do not have an issue. This time the wall thickness between the patterns is .020” and by the time it wraps around the joint line appears on the graphic to be half as wide as it is in pattern field. I have been through my math twice for calculating the distance between the patterns on this diameter all the way out to 8 decimal places.

 

Should I trust the verify and make adjustments or run the part and see how it comes out (which I only have one)?

 

Anyone seen any inaccuracies at this level in verify? Would Vericut be more reliable?

I sounds like you're pushing your graphics to the limit.... or the resolution of your STL

file is bigger than the features you're trying to verify.

In a case like this I Veify my tool paths on a solid model of the finished part and see if I hit it,

but even that may not give you good results.

Vericut would be more reliable as it can compare machined results with design results

to user defined tolerances

Personally, I'd check the math, step through backplot very carefully and run it if I didn't see any problem
