The square and radius end mills have been mainly used for rough cutting due to its large amount of removal volume. The cutting load was only considered by changing the tool feed speed. However, the cutting time becomes long by that change. In this report, the tool path that cuts the interference surface next to the machining surface by five-axis controlled side cutting was generated, and the generated tool path was revised on the basis of the removal volume per unit of time to prevent the sudden change of cutting load by changing tool posture. As the result, the effectiveness of the proposed method was confirmed by machining simulation.
