Crystal Structure Basic Concepts

Crystal Structure Basic Concepts Some Basic Concepts of Crystal Structure: Basis and Lattice A crystal lattice can always be constructed by the repetition of a fundamental set of translational vectors in real space a, b, and c,, any point in the lattice can be written as: r = n1a + n2b + n3c. () Such a lattice is called a Bravais lattice. The translational vectors, a, b, and c are the primitive vectors. Note that ...

Profile milling

Profile millingWhen using a ball nose end mill, the most critical area of the cutting edge is the tool center, where the cutting speed is close to zero, which is unfavorable for the cutting process. Chip evacuation at the tool center is critical, due to the narrow space at the chisel edge.

The Anatomy of an End Mill

The Anatomy of an End Mill · Ball Profile End Mills. This type of tooling features flutes with no flat bottom, rounded off at the end creating a "ball nose" at the tip of the tool. Cutter Diameter. The cutter diameter is often the first thing machinists look for when choosing a tool for their job. This dimension refers to the diameter of the theoretical circle formed by the cutting edges as the tool rotates. Shank ...
