Abstract
The article presents the influence of the angle of inclination cutting edge milling cutter on the milling process of AlZn5.5MgCu aluminum alloy. The study was carried out for two finger mills, three blades with different angle of inclination of the cutting edge. In experimental investigations, the components of cutting forces and surface roughness parameters were registered.
Highlights
AlZn5.5MgCu aluminum alloys are commonly used in the aviation industry - most often for hull structural elements
It can be concluded that the use of tools with a variable angle of inclination of the cutting edge λ significantly reduces the component of the normal to feed force FfN, it leads to a greater surface roughness compared to the surface roughness after machining with a constant angle cutter λ. For this reason, milling cutters with a variable cutting angle λ are suitable for high-performance roughing of aluminum, carried out at maximum cutting speeds and feed
