Introduction to G-Code

All CNC plasma cutting systems use software that has CAD drawing and CAM cutting components to achieve the desired cuts. Because cutting is automated, the quality of the software is incredibly important. The cuts a fabricator would have typically made themselves are now executed by an automated system so software quality will make or break the quality of cuts achieved. When a fabricator invests in an EZCutCNC CNC plasma cutting system, they received a complete system including state-of-the-art software that is user-friendly and produces great cuts. EZCUTCNC software has CAD drawing nd CAM cutting software, as well as multiple part grid nesting, pre-loaded cutting parameters, kerf-compensation, lead-ins and lead-outs, a toolpath generator (G-code), and easy image to vector conversion, as well as remote access for trouble shooting. If you are unfamiliar with what G-code is, it is important to understand it because it is literally what tells your torch where to go.

G-code is code just like in computer programming, it is a language that has the information to position a tool and tell a tool exactly what to do and where. G-code will help tell your CNC plasma cutter where to move the torch, the speed at which to move the torch, when to increase or decrease coolants, and many other things. With good software, you will never have to manually enter G-code, unless you really want to. Your software will automatically generate G-code based on the CAD drawing and CAM cutting software. Scan2Cad offers a helpful description of just how G-code works within your CNC plasma cutting system, “To begin with, an initial block of material will be loaded into the machine. Then, following the instructions given by the G-code, the cutting tool cuts away material from the block to produce the finished product. G-code is one of the most widely used programming languages used to control automated machine tools. Most CNC machines execute G-code, although other CNC languages exist, such as Heidenhain, Mazak, and other proprietary formats. CNC machinists can either write G-code from scratch, modify existing G-code, or generate G-code using CAM software. CAM software can generate G-code from either images or CAD files. In today’s extensive CAD industry, there are also CAD editing programs that automatically convert CAD files into G-code. There are also richly-featured G-code editors that can be used to simulate G-code, or to translate G-code into conversational CNC.” With a basic understanding of G-code, you will be able to better understand your CNC plasma cutting system and achieve the kind of cuts that you want!
