The programming language for CNC five-axis precision machining special-shaped workpieces usually uses G-code (also known as G-code or RS-274) or a similar programming language.
G-Code is a widely accepted CNC programming language for controlling CNC machine tools for machining operations. It includes various instructions for defining the workpiece shape, size, cutting path, and other operations. In five-axis machining, G-code is used to define the movement trajectory of the tool to achieve complex three-dimensional shapes and surfaces.
Here are some basic elements of G-code:
Comments: Used to explain the code and provide additional information.
Preprocessing commands: for toolpath calculations and optimization, tool compensation, etc.
Cutting Mode command: Used to define the cutting mode of the tool, such as parallel, radial, helical, and so on.
Interpolate command: Used to interpolate linearly or circular arc between two points to move the tool smoothly.
Rotation axis command: Used to control the movement of the rotation axis, such as rotation angle, rotation speed, etc.
Tool commands: Used to select tools, set tool parameters, and more.
Coolant command: Used to control the flow and type of coolant.
Other commands: Includes various other commands for controlling machine operation, such as workpiece positioning, depth of cut, feed rate, and so on.
When writing G-code, CAM (Computer Aided Manufacturing) software is often used to generate toolpaths and associated G-code. CAM software provides an intuitive graphical interface that allows users to define machining areas and toolpaths with simple drag-and-drop operations, as well as simulate machining to check for potential errors and problems. The generated G-code can be transferred to a CNC machine for machining.
