Selection Of Dimensions (1947)

The film discusses the importance of selecting appropriate dimensions in engineering drawings to ensure that machine parts function correctly together. It emphasizes understanding the machine’s operation, the relationships between mating parts, and the manufacturing processes involved. Key points include the necessity of providing direct, correlated dimensions for critical parts, considering tolerances, and using standard measurement practices. The film illustrates these principles through examples, such as dimensioning a movable jaw in a drill press vice, highlighting the need for precision and clarity in engineering documentation.
