Q1. What is tolerance stack up & what is IT grades?
Ans. 
Tolerance stack up is the accumulation of variations in dimensions and tolerances in a product design. IT grades are international standards for tolerances.
• Tolerance stack up occurs when the cumulative effect of individual part tolerances results in a deviation from the intended design.

• IT grades, such as IT01, IT0, IT1, etc., are used to specify the level of tolerance allowed for a particular dimension or feature.
