G1 will do the same thing leading zeros are not needed.įeed rates for milling are given as feed rate/min. It will travel at whatever speed was set by the last F code. G01 moves the tool in a straight line to the designated coordinate. All programs begin and end with a percent sign, and every program has a program number following the first percent sign, such as O0007. A typical program will make use of all, or most of, these letters. In addition to G-codes, CNC programming makes use of M codes for miscellaneous functions (such as M00 for program pause), S codes for spindle speed control, F codes for feed rates, and T codes for tool selection. Some commands are non-modal to perform a temporary activity once.Ī line of code for the above X move might look like this: G21 G00 X22.0
For instance, G21 sets the machine to metric. Most G-code commands are modal, meaning they stay in effect until changed by another command. If the command gives a Y value, the rapid positioning command would move the tool the fastest way possible, not necessarily along a single diagonal line. For example, G00 tells the machine to quickly move the tool to the specified position, say X22, which, if the machine is set in the metric mode, would move the tool to the right of the origin by 22mm.
The “G” in G code signifies that a preparatory command follows.

A series of controlled feed moves, resulting in a workpiece cut, a bored hole, or a decorative profile shape.Since G-codes are preparatory codes, in a CNC program they begin with the letter G and direct the machine. The zero position can be moved to find, for instance, the corner of a workpiece. Homing the machine will bring the three axes to this X0, Y0, Z0 position.
The intersection of these three axes marks the machine’s home position. For instance, if the table was moved left while the tool remained stationary, this would still produce a positive machining action. Positive motions refer to the cutter relative to the workpiece. Similarly applied, the right-hand rule helps to identify axes on other CNC machines. In placing one’s right-hand palm up on the machine’s table and extending thumb, forefinger and middle finger so they create three axes, the positive X-axis points in the direction of the thumb the positive Y-axis, in the direction of the forefinger and the positive Z-axis, in the direction of the middle finger. The three axes can be identified on a vertical milling machine, for example, by the right-hand rule. OrientationĬNC machines are based around the Cartesian coordinate system, sometimes called rectangular coordinates. For additional information please see the related other articles in this series. This article will briefly describe G-code and its application to CNC machining. The standard version of G-code is known as RS-274D, although other versions do exist for CNC machines with compatibility issues.

G-code fits somewhere between conversational control, where the operator describes the part and how it should be machined, and CAM, or computer-aided manufacturing, programs, where software develops the necessary toolpaths, feed rates, and so on needed for the CNC machine to cut the material into the finished part.Īlthough G-code as a term is often used interchangeably with Numerical Control (NC), it is actually only one component and works in conjunction with other codes to perform the appropriate tasks.

It is equivalent to manual programming where each operation is spelled out line-by-line and is separate from M-code and T-code, codes that control the machine and tooling. It tells numerically controlled lathes and machining centers how to move tools in order to perform various cutting operations. G-code is the operational language for CNC machining.
