Introduction to Numerical Control Machines
Numerical control can be defined as the automation of manufacturing process using programming languages that is controlled using letters, symbols and symbols. The instructions to produce a particular work job are in the form of numbers in numerical control machines. The instructions form program which changes with the job. The present chapter is therefore an attempt to introduce the numerical control machines. The chapter discusses on the basic components of the NC system. It outlines the basic NC procedure. Discussion is made on the NC coordinate systems and the motion control systems. The chapter concludes with the discussion on applications, advantages and disadvantages of NC.
