Setting up a component datum and the tooling,One of the tasks of the setter/operator is to position the component datum and the tools that are going to be used for machining a program. The programmer cannot always specify certain information such as the exact distance of the component datum from the machine datum, or the precise diameters or lengths of the tools to be used.

Line format and program structure,A CNC program is a set of instructions that is read by the machine tool computer system to control machine slide movements, tool movements and additional miscellaneous functions. There are two types of CNC programming: .. Most CNC machines use word address format, mainly for historical reasons — many of the first machines used this type of format.

Operating parameters for a CAM system,When you use a CAM system, you need to set up some additional parameters in the initial start-up procedure, over and above those required by a CAD system (discussed in Learning Assignment 9). These parameters relate to the ultimate generation of a CNC program to machine the drawn component and may include the following:
