Selecting helical side finishing creates a continuous spiral finishing pass on 2.5D milling features. The tightness of the spiral is controlled by the Pitch parameter. A smaller pitch results in a tighter spiral.
If Helical side finish is turned the features is finished in a single pass or cut in numerous passes with constant Z heights as shown below. See Finish pass z increment or Individual levels for more information about other finishing options. See Helical ramping for information about approaching a feature using a helical move.
