Understanding and Writing G & M Code for CNC Machines
Loveland, Thomas
Technology and Engineering Teacher, v71 n4 p24-29 Dec 2011-Jan 2012
In modern CAD and CAM manufacturing companies, engineers design parts for machines and consumable goods. Many of these parts are cut on CNC machines. Whether using a CNC lathe, milling machine, or router, the ideas and designs of engineers must be translated into a machine-readable form called G & M Code that can be used to cut parts to precise dimensions and tolerances. Machine operators and engineers must be able to read the G & M Code that forms the basis of communicating with CNC machines. If there is a problem in manufacturing a part, the ability to read and write G & M Code is crucial to getting production back on line quickly. In this article, the context and skills of using mathematics in a technology laboratory are developed around a G & M Code activity. This G & M Code activity meets national standards and helps students link their mathematics content to the applied projects they work on in technology and engineering labs. Whether computer-aided drafting, robotics, machining, or design, technology students benefit from understanding and utilizing procedural and conceptual mathematics to solve problems. That understanding and use of mathematics in an authentic project can help prepare students for their future STEM-based careers. (Contains 2 tables and 4 figures.)
