Standard in the CNC industry, Mastercam takes input from the programmer everything it needs to doand it produces the right G- and M-codes.

Mastercam is a code-producing software that helps programmers create the right code for the project. While machines are frequently programmed directly with G-code, a CNC programmer often uses a high-level computer aided manufacturing CAM programming tool. G-Code for CNC Programming (2020 Update)Д¬NC lathes use G-code and M-Code too, but you can expect some different commands and sequences for turning. So far, the program has set the geometry and the spindle speed. These are comments for the programmer and operator. Anything in parentheses is not read by the machine. Some examples of code programming lines and what they mean. This chart is just a sampling of all the program lines that could be included in the code. Like any language, CNC has many other aspects to it. Unlike G-code, however, M-code can be more specific for different machines and is more customizable.Д«oth types are needed to have a CNC machine perform its functions. Some of these functions may vary by the specific machine. Examples include spindle rotation start and stop, coolant on and off, pallet change, etc. M-code controls miscellaneous functionsand typically these can be thought of as non-geometry machine functions. For example, G01 followed by a sequence of X, Y, or Z positions, means all linear feed moves occur at G The X and Y axes position the spindle precisely to perform a cut or other function. G-code can repeat an action indefinitely until it is stopped. These codes, such as G00, are followed by a geometric location. It moves the tool to part geometry at the maximum rate and is generally used to move the tool and part from near to far or vice versa. Simply put, G-code is a software programming language used to control a CNC machine.ДЄnd, even with complex CNC machining, G-code is written in a straightforward, logical way. G-code makes CNC machines consistent to program and flexible, able to produce different parts. The programmed codes, along with the right tooling in a CNC machine center, allow for correct and repeatable part manufacturing. When using G02 with G01 and G03 Counter clockwise arc any shape can be machined.G-code is the programming language used to control CNC machinery.ДЄ program is a sequence of codes and data that tells the machine what to do. The centre point of the arc can also be defined using I, J, and K values.

If a feed rate is already active there is no need to add it to this line unless you wish to change the feed rate for the machining of the arc. G02 is used to machine an arc or radius in a clockwise direction and G03 is for anti clockwise. When programming a profile it is easier to use cutter compensation G41 and G42 then you do not need to allow for the radius of the cutter when plotting your tool paths, you can simply use the dimensions on the drawing and the machine will offset the cutter to achieve the correct dimensions. It is not common to cut with the Z axis as well as X and Y but it is possible if needed. This command can be used with all axis cutting at the same time, or just one. A typical block would look like G01 X F In much the same way, a feed rate F50 is only needed once until you want to change the speed in which you are cutting. This command has to have a feed rate F active before it will run. A G01 command is used when you are cutting in a straight line. It will increase your machining time by a second or two but it will help avoid a 3 Axis crash. If you are unsure it may be wise to move the X and Y axis first, then on a separate line, move down in Z. When using a rapid move, be aware of any clamps, vices, and parts that may be in your path. The top speed is set by the machine parameters and therefore is only controllable by the operator using a rapid override control. It is used when the cutter or tool is not removing material so that the time it takes to machine the part is as quick as can be. G00 is the rapid travel command in G Code. Keep your hand on the feed knob and come in slow for the first time run. Some machinists like to rapid as close to the part as possible but I advise giving yourself at least 1mm clearance. This command is used when the tool is not touching the part to rapid move, normally used when going home for a tool change and returning with a new tool.

Today we are going to examine this group and how they are used to control the machines. These standards are used on CNC Lathes, Milling machines, routers and more recently by 3D printers in a very basic form. Although Different manufactures of the machine tool may adopt their own use for certain G Codes there is a core group that is common on every machine tool.
