NUMERICAL CONTROL Meaning and
Definition
-
Numerical control (NC) is a technological system that automates the operation of a machine tool or other manufacturing equipment using pre-programmed instructions. This method of control involves the use of numerical codes, which are prepared offline and loaded into a computer or controller that operates the machine.
The fundamental concept behind numerical control is to replace manual control of a machine with automated instructions that provide precise commands for various operations such as cutting, drilling, milling, or shaping. These instructions are typically represented in the form of alphanumeric codes that describe the specific tool movements, feed rates, cutting parameters, and other critical variables required to perform a particular task.
NC systems allow for greater accuracy, repeatability, and speed in the manufacturing process, minimizing errors and optimizing productivity. This technology also enables complex designs and intricate patterns to be easily produced in a wide range of materials.
Historically, numerical control started with punched tapes or cards containing the instructions, but it has evolved to utilize computerized systems and software. Today, NC has further improved with the integration of computer numerical control (CNC), where the instructions are conveyed using computer-based languages and machine controllers. CNC provides even greater control flexibility, program storage capacity, and sophistication.
Numerical control has revolutionized the manufacturing industry by offering increased efficiency, improved accuracy, reduced labor costs, and enhanced production capabilities. It has become an integral part of various sectors, including metalworking, woodworking, plastic production, and even the fabrication of electronic components.

Etymology of NUMERICAL CONTROL
The term "numerical control" originated in the mid-20th century from the combination of two words: "numerical" and "control".
- "Numerical" is derived from the Latin word "numerus", meaning "number". It refers to anything related to numbers or numerical values.
- "Control" comes from the Middle English word "countrollen", which initially meant to keep a check on something or to verify accounts. Over time, it evolved to mean regulating or directing the behavior or actions of something.
When these two words are combined, "numerical control" refers to a method or system of controlling machines or processes using numerical values or instructions. The term was first used to describe the emerging technology of using punched cards to control the operation of machine tools, such as lathes and mills, in the manufacturing industry.
