Industries in the machinery manufacturing subsector create end products that apply
mechanical force, for example, the application of gears and levers, to perform work.
Some important processes for the manufacture of machinery like forging, stamping,
bending, forming, and machining are used to shape individual pieces of metal.
Processes, such as welding and assembling are used to join separate parts together.
Although these processes are similar to those used in metal-fabricating establish-
ments, machinery manufacturing is different because it typically employs multiple
metal-forming processes in manufacturing the various parts of the machine. Moreover,
complex assembly operations are an inherent part of the production process.
In general, design considerations are very important in machinery production.
Establishments specialize in making machinery designed for particular applications.
Thus, design is considered to be part of the production process for the purpose of
