Ergonomics

Ergonomics is the study of people while they use equipment in specific environments to perform certain tasks. Ergonomics seeks to minimize adverse effects of the environment upon people and thus to enable each person to maximize his or her contribution to a given job.

(Cherie Berry,A Guide of Ergonomics, pg6)

Flexible manufacturing lines

Organize computer-controlled machinery in production lines instead of cells. part transfer is through hard automation, product flow is more limited than in flexible manufacturing systems, but the throughput is larger for higher production quantities

(Kalpakjian S., Schmid S.R.,Manufacturing Engineering and Technology, 5th Edition, pg.1148)

Shop-Floor Programming

In shop-floor programming, CNC programming software is used directly on the machine-tool controller. This allows higher-level geometry and processing information to be sent to the CNC controller instead of G-code. G-code is then developed by the dedicated computer under control of the machine operator. The advantage is that any changes that are made to the machining program are sent back to the programming group, are stored as a shop-proven design iteration, and can be re-used or standardized across parts. Before production begins, the programs must be verified, either by viewing a simulation of the process on a monitor or by first making the part from an inexpensive material, such as aluminum, wood, wax or plastic.

Creep

Plastic (permanent) deformation occuring at a relatively high temperature under constant load over a long time period.
