Metalworking occupations include: The oldest of the metalworking occupations Smith (a.k.a. metalsmith), such as blacksmith or silversmith Jeweler Founder The machining trades Production machinist, which may involve various related machining occupations that often overlap: Manual machine tool operator CNC programmer, the person who takes the drawings made by engineers and draftspersons and creates a CNC program to cut the part CNC setup hand, the person who sets up the machine and its tooling before the operator takes over CNC operator, the person who: feeds stock to the machine, changes cutting inserts, checks quality, cleans and lubricates the machine, etc. Tool and die maker and related machining occupations: Moldmaker Patternmaker Modelmaker The fabricating and erecting trades Steel erector, also known as an ironworker Welder Boilermaker Pipefitter Millwright Blacksmith Gunsmith Marquetarian (though often dealing exclusively with wood, ivory or other non-metallic materials) Farrier Furniture maker Pewterer Damascener Other occupations within a metalworking plant Laborer, unskilled and semiskilled workers who support metalworking operations and who often develop their skills to move into the other occupations listed here. Sometimes laborers' positions may be called by more specific names, such as oiler. Technology in general, and automation especially, tends to exert pressure against laborer-type job creation, with the lowest-skilled positions being most at risk. For example, so-called labor gangs, groups of men assigned to shoveling or other manual tasks, are not employed nearly as much as they used to be, especially in developed economies. Some jobs, despite being classifiable as semiskilled work, actually require quite a bit of talent and experience to be done well, for example, band saw operators or buffing and polishing workers. Rigger, a person specializing in the skills needed to move large, heavy objects Heavy equipment operator, a person who operates engineering vehicles (also known as heavy equipment) Shipping-and-receiving workers, such as forklift drivers and packagers Manager, a businessperson who manages the work of others Quality assurance (QA) staff, who are usually inspectors with additional training in quality management systems, which focus not only on finding defects that have occurred (inspection) but also on preventing defects from happening in the first place, by engineering processes that lower the probability of their occurrence. The latter causes QA to overlap with statistics and industrial engineering. Weld quality assurance staff, ensuring the quality of weldments. Weld inspectors require training in metallurgy that ranges anywhere from an undergraduate familiarity all the way up to, in
