| Description
| Tolerances and fits are the controls for product functionality, manufacturing economy, and test correctness. Tolerances are part of the design process, giving the part a reasonable scale of error, making it interchangeable. The fit is the tightness of the combination when the parts are in various tolerances. This Course content:
(1) Terms and Definitions of Tolerance and Fit
(2) Types of tolerances.
(3) Tolerance annotates method.
(4) Types of cooperation: clearance fit, transition fit and interference fit.
(5) Fit system: base hole system, base shaft system.
(6) Choice of tolerances and fits.
(7) Geometric tolerances.
