1 Brief description
Module Objective:
Upon completion of this module you can understand the basic functionality and requirements of a
CNC controller
Module description:
CNC machines replicate the functions of a manual machine through the use of a sequential program,
this program replicates the movements of a manual machine through the so called “CNC program” .
Geometric relationships of the component to the machine are achieved with (Tool and component)
numeric compensations. These compensations mathematically compensate the difference between
component, Tool and machine.

Section 2
The difference between a Manual machine and a CNC machine is a logical
difference based upon numerical values. This overview module and the
following CNC modules should help explain the myth of CNC.

Module objective:
Upon completion of this module you will understand the basic structure of an NC program
Module description:
We use a basic structure when writing a program to give some kind of order to the program, this will
also help when performing a “Block search”.

Section 2 Basic structure
2.1 Basic structure of NC program
There are five basic parts to an NC program.
1. Basic startup G functions.
2. Call tool and set spindle speed, feed, coolant.
3. Set geometry to cut component.
4. Tool to safe position
5. End of program

You will note that for each tool there is always :
• Call tool etc
• Geometry for component
• Safe position for tool change
This will be the same for ever tool that is written in the NC program
If you keep to a good basic structure, this will make the program safer to
run and easier to perform a block search.
