Attention for cutting parameters of CBN inserts
Attention for cutting parameters of CBN inserts
1. When roughing, the metal removal rate and the necessary tool durability should be ensured. Therefore, the maximum cutting depth(ap) is preferred, and the next, the larger feed rate(f) is selected. Finally, according to the requirements of CBN inserts durability, determine the right cutting speed.
2. In the finishing process, the requirements for machining accuracy and surface quality of the workpiece should be ensured first. Therefore, the smaller feed rate(f) and the cutting depth(ap) are generally selected, and the higher cutting speed Vc is selected as much as possible.
