The more innovative Minié ball, however, was different. The ball was not round, but rather had a conical shape with rings around the bottom. It was also made of lead, a softer material than the iron that many other types of ammunition were made from.[3] William Tod Helmuth goes on to write that:Web

A ball valve is a quarter-turn, on/off valve that relies on a pivoting ball to control the flow of liquid or gas. The ball has a bore (or hole) in it through which media passes, and its position relative to the pipe walls dictates whether the valve is open or closed. Ball valves are quick-operation and used for sealing and shut-off operations.Web

The bullet was made out of soft ...Web

As the channel is narrow, the radius of the ball-end of the cutter has to be small, i.e., 2 mm. Therefore, the conventional cylindrical ball-end cutter (i.e., BR2C0 in Fig. 17) would be too soft for the job, while a ball-end cutter with a conical shank (i.e., BR2C2 in Fig. 17) will tremendously raise the stiffness of the tool [1].Web

Milling of free form surfaces using ball-end milling is the main operation in this application, known as sculptured surface milling (SSM) (Choi and Jerard, 1999).
