Basic Math For Ballnose Tools  Modern Machine Shop
Nov 01, 2003· The ballnose end mill is a special sort of tool. Its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3D forms. And yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING
If a ball mill contained only coarse particles, then of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.

Gunpowder  Wikipedia
Gunpowder, also known as the retronym black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.It consists of a mixture of sulfur (S), carbon (C), and potassium nitrate (saltpeter, KNO 3).The sulfur and charcoal act as fuels while the saltpeter is an oxidizer.

Smelting  Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

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.
