Reversing ToolCut Direction in Lathe

[nofalloff]

This seems simple but I can't seem to get it to work. I have a part that has the finish pass starting at X0 Z0 and profiling and arc and then a flat that ends at an o-ring groove that is at Z-.56 X1.125. Id like to cut this with the tool moving away from the chuck (reverse) or in the Z+ and X- directions so that the tool path ends at Z0X0. I can create a finish path that works fine when the tool is traveling in the Z- direction but if I try to reverse the chain or re-chain from the opposite direction I get a rapid boundary violation error and a tool path that is just straight and nowhere near the profile geometry. How do I create a reverse tool path like the one I need?

 

Thanks

Make sure your tool comp is set correctly (left vs right). You also need to adjust your Plunge Parameters to allow plunging since you are cutting towards the centreline of the part.

Make sure that the lead in parameters are set properly (probably to perpendicular if memory serves), and also make sure that the plunging parameters are set to allow plunging in both the X and Z directions.
