Ramping to Success - In The Loupe - Machinist Blog

May 10, 2017 Ramping refers to simultaneous radial and axial motion of a cutting tool, making an angular tool path. Oftentimes, this method is used to approach a part when there is a need to create closed forms such as pockets, cavities, engravings, and holes. In doing so, the need to plunge with an end mill or drill to create a starting point is eliminated

Milling holes and cavities/ pockets - Sandvik Coromant

Internal shoulder milling and plunge milling require a starting hole and should be compared to ramping a cavity directly into a solid block. Ramping (3-axes) has an advantage because it only requires one tool and can produce 3D-shapes, making it suitable for profile milling.

Basic End Mills Technical Information | MSC Industrial

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.
