Securing stock for rotary machining

Postby PeterM » Thu Aug 01, 2019 9:08 pm

Hello,
I'm using VCarve Pro V9.5 and am somewhat new to creating rotary machining tool paths....

I am trying to machine some handrail fittings and have some 1" dowels attached at the ends of the model (see attached screenshot) to allow for proper machining.
The issue I have is that in VCarve Pro, in the machining simulation, it appears that the very ends of the dowels are being machined in the Z direction which is not the desired effect. I'd like the dowels to still be securely connected to the oversized stock that will be mounted in my CNC. Would anyone have a suggestion as to fix this issue?
Thanks,
Peter

Use vectors to control what will and won't be machined. When you generate the rough or finish 3D toolpath choose machining Limit Boundary/Selected Vectors

Okay - Brilliant!
Thanks for that. I saw that option but was confused on how to do that. I was thrown off by the fact that when I select my whole model in 2D that it turns a different color (very dark) than I usually see when selecting just one line (magenta). After creating an appropriately sized rectangle and selecting it and the model in 2D everything works properly!
Best,
Peter
