Chip formation when rough boring is very important. An ideal chip should be "C" shaped or look like a six or nine. The chips should also be short as illustrated below.<br/><br/>
Proper chip formation is a function of the feed rate and the chip breaker on the insert. Generally the feed rate should be 25% to 35% of the width of the chip breaker.<br/><br/>
*If the chip does not break, increase the feed rate provided that the following conditions exist:*
* The part and the fixture are sufficiently rigid;
* The machine has sufficient horsepower;
* The machining allowance does not exceed the stated maximum;
* The tool is not overly long.<br/><br/>
If the chip does not break with the increased feed rate, it may be necessary to change to an insert with a smaller chip breaker.<br/><br/>
It is important to remember that the thin, wide chip produced from a low feed rate and a large machining allowance is difficult at best to break. As a general rule, the feed rate should be 10% to 30% of the machining allowance.
