High-feed milling is a category of face milling with shallow depths of cut and significantly higher feed rates. This application is an excellent choice if you are looking to machine a large quantity of material in a short period of time.
Indexable tools with a low pressure angle of approx. 10° to 15° are often suitable for high-speed milling. Using a low pressure angle reduces the chip thickness by up to 80 per cent compared with tools with a 90° pressure angle. In this type of machining operation, feed rates per tooth (f((z))) of well over 1 mm are common. A further advantage of high-feed milling cutters is that the cutting forces flow almost entirely in the direction of the spindle. The result is minimal vibration during roughing operations with large overhangs. A toric tool can imitate these effects. If the depth of cut (a((p))) is smaller than the cutting radius, the effective pressure angle decreases. The smaller the depth of cut, the more the distribution of forces shifts in the direction of the spindle.
