How the Tool Helix Affects Manufacturing -

Cutting forces on an end mill have axial and radial components that affect how it functions. The radial component often leads to vibrations and the axial component affects the force of the mill against the holder. These components are varied by changing the helix angle on a tool, and different angles are better for different

Calculating Feeds and Speeds -

The next thing to be considered is the direction of cut, which is the direction the cutter is fed into the material. Conventional milling or cutting forward is the most commonly used method. With this method the work is fed against the rotation direction of the cutter. The other method is climb milling or cutting reverse.

Milling Step-over Distance Calculator

In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.
