High Speed Cornering Option

The General tab of the Roughing Cycle dialog features a High Speed Cornering option.

Setting

Relative
Advantages/Disadvantages

Toolpath

A radius is introduced into sharp toolpath corners. This is the default.

Lower machine stresses. Reduced toolpath length. Toolspeed maintained. Reduced cycle time.

More CNC code.

All toolpath corners have an angle from the profile, however sharp.

Less CNC code.

Higher machine stresses. Increased toolpath length. Toolspeed reduced. Increased cycle time.

Note

The final pass does not have introduced rounded corners. This always follows the profile, subject to the Minimum Radius setting (0 in the case of the illustration).
The introduced corner radius is not fixed. It is a percentage of the % Stepover setting for the cycle.
