During tooling, manufacturers use various tools to help shape, form or finish work pieces. This process in the past occurred with the assistance of manually operated tools. Today, automation often permits more rapid machining. Specialized devices known as “jigs” and “fixtures” assist tooling during production.

In its most basic form, a jig helps maintain an optimal positional relationship between a work piece and a manufacturing tool. During the assembly process, it may also promote the positioning of different parts of a work piece relative to one another. Jigs usually expedite machining processes, Trazza can design and produce custom fixtures.
