镗刀在镗刀杆上装夹时应尽可能伸出较小的距离，但需要注意切削刃伸出长度应符合加工余量，并有利于排屑。
Boring as far as possible out smaller distances in boring bar clamping, but need to pay attention to the cutting edge length should meet the machining allowance, and is conducive to the chip.
如果残余量很大的话，IT就会自动的在这些区域加一些切削层以降低刀具的负荷。
If there is a lot of rest material to be removed, then IT will automatically add extra passes into those areas to reduce tool loading.
