I will. If the feed amount of the intermittent cutting is set to 200% or less, the machining time becomes shorter than that of the conventional example 3. In other words, by setting the temporary retreat separation length R within the range of 5 to 200% of the intermittent cutting feed amount, reliable cutting of chips can be achieved without reducing machining efficiency. is there.
