Different types of tolerances. To learn how to effectively tolerance parts in engineering drawings. Allowance/Clearance Expressing tolerances in of Mechanical Engineering and MechanicsTolerancing Definition: Allowance for a specific variation in the size and geometry of part. Why is it needed: No one or thing is perfect ! Hence, engineers have come up with a way to make things close to perfect by specifying Tolerances!
