Five Axis Cycle - Round Corners Option

In the Five Axis Cycle (General tab) you can set a Round Corners value to prevent 'fishtails'.

Fishtails are where the switch between cutting surfaces introduces extra sharp corners into the toolpath.

Here is a SWARF type situation where the tool is cutting on its side into a corner. (There is no gouge checking.)

The non-blank setting is a radius value from the 90° corner at which to trim the toolpath.

This leaves a gap, which is then treated according to the 'Gap Link' settings in the cycle dialog's Links tab ('Smooth' in this example).

A 0 value just removes the fishtails.

You might want to leave a blank setting to disable fishtail removal:

The fishtail removal can lead to unexpected results - such as missing sections of toolpath.
The fishtail removal introduces a calculation overhead, delaying the cycle generation.
