In figure 4, we can see a G-Code program that engraves a metal surface. I will cover small portions of G-Code when it is important for presenting my case. G-Code has variations based on machine being used and the manufacturer, so a code used in one machine is not always compatible with a machine of different make. G-Code is a programming language that is commonly used in CNC Machines as stated in the definition of CNC. G-Code generated on Haas NGC that performs and Engraving cycle. For context figure 3 shows a menu in both the controllers. In sections where this is true I will explicitly state which controller is under consideration. These two controls have different feature sets and some portions of my findings only apply to one of these controllers. They currently have two variants the Classic Control (CC) and the Next Generation Control (NGC). These controllers are paired with a CNC to provide the operator with a UI to interact with the machine. Haas like many CNC manufacturers have a separate range of controllers for their machines.

All findings will apply to present and past Haas CNCs and with slight variation should apply to most industrial CNCs. All the testing and observation in this study were conducted on Haas VF4, DT1 and Simulator. Haas Automation Incorporated is an American CNC manufacturer. Although mills can be manual, we will focus on the CNC variant. These machines are used for subtractive manufacturing by reducing a stock piece into a usable part. In this context, a mill refers to a machine that has a rotating bit that is capable of moving/cutting independently on the three Cartesian axes. Image of Sankvik Shell Mill milling through cast iron alloy. These machines form the basis of industrial automation and are now being introduced in the offices, schools and homes in form of 3D printers, mills and lathes. Some common examples of such machines are shown above in figure 1. Image of Haas VF2 Super Speed CNC mill.ĬNC is the acronym for computer numerical control which is used to refer to machines that are actuated by a computer executing a set of commands.

This is in no way an exhaustive list of non-colloquial terms used in this document but should be sufficient for the purpose of presenting my findings. To provide some context to this document here is a list of definitions of common terms that are used throughout this report. Classic Control and Next Generation Control.
