G code, how to fill it?

G code is a programming language used in numerical control system, which is used to control machine tools to process workpieces. To write G code, you need to know the machining mode of machine tool, the coordinate system of machine tool and the grammatical rules of G code.

Here are some basic steps to write G code:

1. Understand the coordinate system and processing mode of the machine tool.

The first step in writing G code is to know the coordinate system and machining method of the machine tool you are using. Common coordinate systems are rectangular coordinate system, polar coordinate system and rotating coordinate system. It is important to know the machining mode of the machine tool, because it will help you determine the correct cutting speed, feed speed and cutting depth.

2. Select the appropriate code and edit the program.

According to the machining mode of the machine tool and the geometric shape of the workpiece, choose the appropriate G code and write the program. You can write the code manually or use CAM (Computer Aided Manufacturing) software to generate the code.

3. Test procedures

Before actual machining, test the program to ensure that the code is correct and avoid damaging the machine tool or workpiece. You can use simulation software to test it. It can simulation of machining process and check whether the code runs correctly.

4. Run the program on the machine tool

Upload the code to the machine tool controller and run it in the machine tool unit. During the operation, you need to monitor the state of the machine tool to ensure the correct machining process.

The above are the basic steps to write G code. It takes a long time of practice and experience to master G code writing skills.
