Numerical Control (NC) refers to the group of automated machines, such as drills and lathes that can carry out manufacturing instructions from a program. These machines are used for various processes such as milling, turning, punching, and drilling. Both NC and Computerised Numerical Control (CNC) are used in this field.
Earlier, the machines were hardwired to carry out predetermined tasks or programmed using a very basic machine language. But now, they are equipped with microprocessors and can be programmed with higher level languages like APT and COMPACT II. These advanced languages can even automatically create the tool path which outlines the physical movements needed to complete the operation.
FAQs
What is numerical control?
Numerical Control (NC) refers to a group of automated machines that can carry out manufacturing instructions from a program, such as drills and lathes. NC machines are used for various processes like milling, turning, punching, and drilling.
What is the difference between NC and CNC?
NC stands for Numerical Control, while CNC stands for Computerised Numerical Control. Both are used in automating manufacturing processes. NC machines are programmed using higher-level languages like APT and COMPACT II, while CNC machines use a computer to control the tool operating process.
What are the benefits of using numerical control?
The benefits of using numerical control include increased precision, decreased scrap rates, and reduced labour expenditures. NC machines can carry out tasks repeatedly without requiring much attention from an operator, which increases efficiency and productivity.
Conclusion
Numerical Control has revolutionised manufacturing processes by automating tasks that were earlier done manually. With the use of high-level languages and microprocessors, NC can perform tasks with increased precision, efficiency, and speed.
