• Investigation of lead and tilt angle effects in 5axis ...

    following cut cases. In 3axis ballend milling, it only depends on the radius of ballend mill and step over. However, in 5axis ball end milling, it may also be affected by the tilt angle while lead angle has no effect on the scallop height. If the step over s is lower than 2Ro cost, the successive tool paths intersect on the parts
