unequal helix end mills theory

US9346109B2 Unequal helix-angle end mill Google Patents

An unequal helix-angle end mill includes a cutting part and a handle part. The cutting part is provided with a plurality of flutes, each spirally extending from the bottom end to the handle part. The face of each flute facing the cutting rotation direction is a rake face, wherein the rake face and an outer peripheral face of the cutting part are intersected to form an outer peripheral blade

Benefits & Drawbacks of High and Low Helix Angles In The

Feb 05, 2020 Helix Angle: An Important Decision. In summary, a machinist must consider many factors when choosing tools for each application. Among the material, the finish requirements, and acceptable run times, a machinist must also consider the helix angle of each tool being used. A slow helix end mill will allow for larger chip formation, increased tool
