Traditional  insert.

Wiper insert Twice the feed, same R_a.

Wiper insert Same feed, half R_a.

R_t= Maximum value peak-to-valley height

R_a= Arithmetic average height of the profile

Rule of thumb

 - Two times feed with a wiper will generate as good surface as conventional geometries with norma feed.
 - The same feed with a wiper will generate twice as good surface compared with conventional geometries.
