Course description
The course “G-code Basics for Beginners” helps you build a step-by-step understanding of the basic logic of CNC programming: from control program structure and coordinates to tool movements, technological commands, editing and simulation.
The material is designed for beginners and built so that the learner does not just memorize commands, but understands what happens to the machine on each program line. Special attention is given to safe code reading, coordinate checking, finding dangerous movements and preparing a program to run.
The course is a good foundation before studying more complex topics: cycles, tool compensation, subprograms, macro programming and practical programming for specific CNC control systems.
What you will learn
After completing the course, you will be able to:
- understand the structure of a simple CNC program;
- read G-code line by line and understand the machining sequence;
- distinguish preparatory, technological and machining commands;
- understand the X, Y, Z axes and the part zero;
- read absolute and incremental coordinates;
- understand the difference between G00, G01, G02 and G03;
- find dangerous movements, especially along the Z axis;
- check the spindle, feed, tool and coolant;
- understand work offsets G54, G55 and G56;
- perform basic NC program editing;
- check a program in a simulator before practice;
- understand what cycles, subprograms and simple code optimization are.
