Fits and Tolerances

Fits and Tolerances: How to Design Stuff that Fits Together by Tarkka

Thoughts: Very machinist perspective heavy and not useful to me right now.

Sometimes, we want pieces to easily slide, while other times, have an exact fit. There is a systematic way to do this, its called first and tolerances.

Different manufacturing techniques have different tolerances. Tighter tolerances = more expensive to manufacture

Fits

• Running fit
• Clearance fit
• Press fit

Look up LC11, and see the size we want to make. We see those tolerances. LC9, LC7, etc..
