Toolpath 3D

It's possible machine 3D surface with experimental 3D toolpath strategy.

From MENU > MILL > Milling 3D

Now define the bottom plane and define the boundary area .

If the boundary area is not selected , it will consider the whole imported model.

With this strategy is taken in consideration the corner radius of the tool.

To define it, open the tool edit screen.

Edit the insert radius property.

Use the half of the tool diameter to get a ball mill or less to get a bull mill.

Now enable the Finishing Operation.

Here you can have a PARALLEL finish strategy.

Or a CONTOUR strategy.

Customizable chord error

From v5 build 295

From post processor dialog > machine properties tab > search and edit "Custom chord error in 3D milling operation" property to customize the chord error used in toolpath generation.
