surface finish blend "twisting"

[specprogrammer]

I dont use blend very often. I usually use flowline but due to surface normal directional issues I'm using it today. So I have a drafted rib that has a radius all around the top and a fillet at the floor. I Chained the boundaries, started the chains in the same place, and the resulting toolpath looks like its twisted or overlapping at the ends. How do I get it to appear more like what I'm used to with flowline?

You got a sample file??? Many things did you try messing with the advanced settings? Have you looked at the HST toolpaths to see if maybe one of them will do a better job? Can you project a toolpath instead of using blend? Have you looked at curve 5 axis using chains and just telling it a 3 axis output? Many ways to skin this cat, but without really seeing it all are guess at this point.

Sometimes I will delete the original surface and re-create it, especially if it wasn't originally created in Mastercam. This usually solves it when this happens to me.

 

Otherwise like Ron said, there are many ways to try to get it done.

Thanks for the quick reply. Went into system config to check my chaining sync mode and it was set to none, changed it to by entity and that fixed it. Thanks again.

Good tip.

 

I'll try that also. I'm constantly making pretzels, ribbons , bows, stalactites and so on. I always just kept trying different directions to get it to work.
