Psychology Mechanophobia is a type of specific phobia that involves the fear of machines or anything mechanical. [ 1 ] The phenomenon frequently arises subsequent to traumatic incidents involving machinery, such as limb loss.
Upset forging increases the diameter of the workpiece by compressing its length. Based on number of pieces produced this is the most widely used forging process. Upset forging is usually done in special high speed machines; the machines are usually set up to work in the horizontal plane to facilitate the quick exchange of workpieces from one ...
Pressey's machine had a window with a question and four answers. The student pressed the key to the chosen answer. The machine recorded the answer on a counter to the back of the machine, and showed the next question. The great idea was to fix the machine so that it would not move on until the student chose the right answer.
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...

Some advantages of cold heading a part over using a CNC lathe or Swiss screw machine include reduced part cost both through production speed (60-400 parts per minute) and the minimal scrap generated from a cold headed part. Also, because the part is formed rather than cut, the grain flow stays intact and creates a much stronger part for its ...
Upset time is the amount of time that the two pieces are pressed together. Flash time needs to be long enough to sufficiently heat the metal before it is pressed together. However, if it is too long, too much of the base metal begins to melt away. The upset time is critical in creating the desired mechanical properties of the finished weld.
Repetition compulsion is the unconscious tendency of a person to repeat a traumatic event or its circumstances. This may take the form of symbolically or literally re-enacting the event, or putting oneself in situations where the event is likely to occur again.
