Surfacing final cut

[Flycut]

It seems like if the last pass of a parallel surface is less than the stepover it simply stops short.

Is there a way to force it or adjust the stepover to respect the final pass?

Still stuck in X5.

With the "regular Surface Finish Parallel" paths, this is not possible. The stepover is a "fixed width", so if there is a "remainder" on the surface that is less than the stepover distance, the path will not make the last pass.

 

You can add an extra tool path: Surface Finish Project, and use a curve that is offset from the far surface edge, the radius of the cutter, if you want that "last pass".

 

Another solution (if you have a Multi-Axis License), is to use the "Morph between 2 curves" path, and set the edge handling to "start/end at exact surface edge". Then, you can use the "Margins" feature to offset the cutter centerline, by the radius of the tool. This will give you a "parallel" path, that has the first and last pass with the tool tangent to the exact surface edge...

Thanks Colin

I'll quit trying.

You could also adjust the stepover distance little by little to find what value divides the surface "evenly" so that the "last pass" gets made. You might have to untrim/extend the edge of the surface to get a perfect last pass. It kind of depends on the geometry you are driving as well.

 

Hope that helps,

whenever I use the old parallel I have always been in a situation where I extend the surface to get everything I want. try extending the offending surface edge at least the step over amount.
