Ramp finishing strategy with radial stock to leave gives empty toolpath

[paul.slaterMZZFE]

I have a problem with a Ramp strategy in that I can get a toolpath to work perfectly with stock to leave at zero to 0.09  but as soon as I opt for any value from 0.91 to 20mm it gives a yellow error and does not calculate the toolpath (toolpath empty) any ideas please? the part is really simple, 200 diameter with a 100 diameter spigot protruding 5mm i am using a 50mm dia face mill and want to leave 1mm stock allowance. (I don't want to use 2d circular as I am trying to use this strategy for other jobs with shapes not just circular) Thanks Paul

Hey Paul,

Could you share your file here? It's often impossible to diagnose without seeing all the settings and whatnot.

Seth -I have attached the model. I have called the tool paths SETH. I have since found a solution to the stock thickness which is to not use a boundary. I cannot understand why I cannot use a boundary and choose Outside or why this should affect the result? I also cannot understand why the tool path has been broken into more than one entry and exit?

thank you for your help. Kind Regards Paul.

Hmm. I guess I'm also not understanding the role that Boundary plays in this. For example, if I select the outside diameter as my boundary, I can put in any amount of Stock To Leave offset and it works, but I'm certianly not cutting outside the Boundary, when I asked it to do so.....

Seth -thanks, glad its not just me. As the part was so simple. Regards Paul.
