The Importance of Machining Tolerances (Metal Machining Video 4)

Machining tolerances refer to the total amount that a specific dimension is permitted to vary in any machined part. Tolerances also include limits and fits. Limits are the extreme permissible values of a dimension, and fits are the degree of tightness or looseness between any two mating parts which are meant to act together. There are three types of fit: Clearance fit Transition fit Interference fit The ISO system for limits and fits is a coordinated system of hole and shaft tolerance for engineering and manufacturing used for cutting tools, material stick ages, etc. They help to keep measurements consistent globally. The video will also share many examples of tolerances, preferred fits, and an example of the ISO system for limits and fits. ADDENDUM: Some of the calculations here were erroneous. Apologies! ☺️ For transition fit (starts 4:10), please see this slide: https://www.sofeast.com/wp-content/up... For the correct data about interference fit (starts 5:10), please see this slide: https://www.sofeast.com/wp-content/up... In the next video, we will explore 'Geometric Dimensions & Tolerances' (GD&T) which defines allowable variations in form, size, and features of produced parts:    • Geometric Dimensioning and Tolerancing (GD...   ________________________________________________________________________ Watch the rest of these metal machining videos in this playlist:    • Metal Machining (Important Fabrication Pro...   If you have any questions regarding producing YOUR metal components or products or just need experienced help, feel free to contact us over at Sofeast: https://www.sofeast.com/contact-us/ You may also like to learn more about the other materials & processes that we're experienced in working with on this page: https://www.sofeast.com/resources/mat...
