Fantastic post - every once in a while I get the urge to read up on backyard foundry stuff and the basic terms are always skipped over. Thanks especially for that section and the images you took the time to create.
Is it efficient to cast in in the rough and then fine tune with machining for precision parts, or is it better to just machine from bar/rod stock if you need a precision part at the end? Actually, I am just assuming machining gives better precision, what are some characteristic tolerances for casting - I'm thinking of stuff like threading.
When you visit a foreign land, your first mode of survival is to understand their language. For you to survive this course, and thus understand the possible terms used in a foundry, I will be you language teacher. I have made the image below to explain most of what you will encounter in sand casting.
Perfect analogy and great advice for #steemstem writers.
It's give me great pleasure that you took time to go through my article. You are right about machining, it has better precision than casting, however cost is something and capability of complex shape is another. So it is better to cast and then machine to the required precision.
Thanks for the support. I am really grateful.
