Autoclave (March 21, 08:30)
An autoclave is an enclosed chamber equipped to apply heat and/or pressure at controlled levels. In FRP composites processing, it is usually a large horizontal cylinder with doors at either end.

Resistance Welding (March 22, 07:53)
Resistance Welding (RW) is a group of fusion-welding processes that uses a combination of heat and pressure to accomplish coalescence, the heat being generated by electrical resistance to current flow at the junction to be welded. The components include workparts to be welded (usually sheet metal parts), two opposing electrodes, a means of applying pressure to squeeze the parts between the electrodes, and an AC power supply from which a controlled current can be applied. The operation results in a fused zone between the two parts, called a weld nugget in spot welding.

Tolerance (March 22, 08:02)
Tolerances are used to define the limits of the allowed variation. Quoting from the ANSI standard, a tolerance is "the total amount by which a specific dimension is permitted to vary. The tolerance is the difference between the maximum and minimum limits."

Self-directed Work Team (March 23, 22:28)
A group of people chartered with specific responsibilities for managing themselves and their work, with minimal reliance on group-external supervision, bureaucracy and control. Team structure, task responsibilities, work plans and team leadership often evolve based on needs and situational dynamics.
