The basic components of an NC/CNC system are described as the program of instructions, machine control unit, and machine tool. The program provides the coded instructions, the machine control unit reads, interprets and executes the instructions to control the motions and functions of the machine tool, which performs the actual machining operations. 4. Part programming 1. Part programming consists of a sequence of instructions to be performed on the NC/CNC machine. 2. This are two types 1.Manual part programming. 2.Computer – aided part programming. CNC 3. In order to prepare part programming the programmer decides the order of the machining operations required to produce a component. .The part program is a sequence of instructions, which describe the work, which has to be done on a part, in the form required by a computer under the control of a numerical control computer program. It is the task of preparing a program sheet from a drawing sheet. All data is fed into the numerical control system using a standardized format. Programming is where all the .
5. Tool changers Several different cutting tools are used to produce a part. The tools must be replaced quickly for the next machining operation. For this reason, the majority of NC/CNC machine tools are equipped with automatic tool changers. They allow tool changing without the intervention of the operator. The document provides information about operating and programming CNC lathes. It discusses key parts of CNC lathes like the headstock, tailstock, and turret. It also covers topics like workpiece and tool zero positions, axis nomenclature, common CNC lathe tools, basic operations like turning and threading, and measuring instruments.
