non-ferrous metal
aluminium alloys

3.22.2 Types of cutting form levels

They are needed to influence the chip drain and the chip shape in order to achieve optimum
chipping conditions.
Examples of types of cutting form levels

b = 1.0 mm to 2.2 mm
t = 0.4 mm to 0.5 mm
For infeeds of 0.05 to 0.5 mm/U and depths of cut of 0.2 mm to 3.0 mm.
The different apex angles ( of the cutting form level need to conduct the chip.
