Numerics

Numerics is typically the term used to describe the numerical field of employment^{[clarification needed]}, or its instructional program at a college or university (or technical school). Numerics occupations can include sub-divisions such as tooling specialist, materials specialist, and others.

Numerical programming

Also known as numerical programming, or numerical control. These terms refer to the programming and use of automated machinery, such as CNC mills/lathes, gantry robots, and other industrial automation equipment. Modern numerically controlled machinery driven by PLC computers (programmable logic controller) or PC-s (personal computer).

The PCs that are used in industrial automation are usually an industrialized version of the x86 family of computers. The main difference between consumer electronics and industrial electronics is that the industrial electronics can tolerate sub-zero temperatures and is designed to withstand dusty and electromagnetically noisy environment. For example, metallic dust can short-circuit electric circuits, which in turn can literally destroy the electrical circuits. Industrial electronics is designed to keep the dust out of the chassis. The electrical noise, which is mostly generated by electrical motors, is dealt with by using optical cables in stead of electrical ones or the electrical data communication (see:bus (computing)) cabling is well shielded (electromagnetic shielding, Faraday Cage).
