Episode #117: The History of Precision
Archer joins us again in the Tangent Cube to give a slideshow presentation about precision. What does it mean to do precision work? How do you get a perfectly straight edge, or a perfectly flat surface? How do we do it in the modern day, and what does that mean for highly precise work done in ancient times?
This was an awesome conversation. We really recommend watching the youtube video so you can see the slides.
Here is the YouTube Video:
Below are some of the slides from GMA's presentation:
I am a surveyor for a contractor in Iowa. A large part of the business is building foundation work and steel erection. I stake out grid and wall lines to ensure anchor bolts and wall dimensions are true to plan dimensions. As quality control check for my staked points I like to keep the residuals between calculated and as-staked points to not exceed 0.01'. After listening to you talk about micrometers and nanometers I feel like my tolerances are not tight enough. THANKS A LOT!! I think I am going to stitch "Johnson" on all of my work shirts. Making my first donation today. Love the show, keep up the great work! SNAKES!!ReplyDelete
I worked for am Aerospace company for 20 years and the precision in manufacturing parts always amazed me. I often would ask machinists how do they make such precise machines and how they developed this. I never got an answer. This presentation satisfies alot of my curiosity.
