Several new features have been added to the B-axis rotary contour toolpath in Mill-Turn.
To start, you can now include splines in your chained geometry.
In addition, new tool angle controls let you specify either a leading or trailing angle for the insert. These are on the Basic Motion Control page. Select the Tool Angle Control option to activate the feature and enter either a leading or trailing angle.
Mastercam will maintain the desired angle with respect to the chained contour. This example shows a trailing angle of 25 degrees:
Finally, a new Fan Distance setting has been added.
This lets you better control changes in the tool axis as the tool moves around a sharp corner. This can create large changes in the tool axis angle in a very small linear distance. The fanning option lets you specify a distance before and after the corner where the tool axis can transition in a smoother and more controlled manner.

These new features are also included in the new A-axis rotary contour toolpath.
