What does "G01" signify in G-code?

The designation "G01" in G-code signifies linear interpolation at a specified feed rate. When a program instructs the CNC machine to execute a G01 command, it indicates that the tool should move in a straight line to the specified coordinates while adhering to the defined feed rate. This is essential for producing precise cuts or movements along a linear path, ensuring that the material is machined uniformly and accurately according to the programmed specifications.

By utilizing G01, operators can effectively control the speed at which the tool moves, which is crucial for various machining operations, including milling. The feed rate impacts machining efficiency, surface finish quality, and tool wear. Understanding and applying this command correctly is fundamental for achieving the desired outcomes in CNC milling processes.
