A review of wood machining literature with a special focus

A study investigating cutting with extreme oblique angles (Fischer et al. 2011) states that cutting with very large oblique angles (45 to normal and above) provides a much better surface finish when compared with orthogonal cutting. This is a result of the time delayed edge engagement and an increased cutting edge contact with the work-piece.
