A metal machinist is a person who operates various types of machines that are used to shape or otherwise cut metal into specific pieces or parts used in industrial settings. This person is responsible for the use, maintenance, and sometimes the repair of metalworking machines, and the metal machinist must be able to read blueprints or plans both for those machines and for the parts being manufactured. Basic math skills are required, as are communication skills and some knowledge of science, especially physics. A high school education is normally required, and in many cases, a post-secondary certificate, a degree program, or an apprenticeship must be completed as well.
Several types of machines may be used in the machining process, and a metal machinist is likely to be trained in the use of many of the machines rather than just one. In some less common instances, the metal machinist may focus exclusively on the use of one machine in a manufacturing setting; he may, for example, work exclusively with an extrusion machine, which draws metal through the machine to create tubes, cylinders, and other elongated shapes. Regardless of the type of machine being used, the metal machinist is probably going to be using computer numeric control (CNC) programs to control the cutting process.
CNC machines use computers that can be programmed with the specific tolerances of the parts to be machined. This allows the metal machinist to create a part over and over again to the same size, shape, weight, or other specification. The use of CNC machines will require training, and the machinist may have to earn a professional certificate in order to operate such machines. In other cases, the machinist may take a job as an apprentice, during which time he will work under the guidance and supervision of a more experienced machinist. The more experienced machinist can teach the apprentice how to use CNC programs properly and efficiently.
Other training will involve safety procedures in keeping with any governing body that outlines worker protection policies in the workplace. Machining can be a dangerous job, since machines often feature moving parts and cutting surfaces, so the metal machinist must be trained to operate the machines properly and protect himself and others from injury. The use of safety equipment such as hard hats, goggles or safety glasses, and ear protection. In some cases, gloves, boots, and aprons will be necessary.
