Mechanical Measurement and Inspection Technology

What is tolerance in mechanical measurement and inspection technology?

• Allowable limit or variation in a dimension or property of a part or product

• The maximum limit of a dimension or property of a part or product

• The process of inspecting a part or product without any variation

• The process of measuring a part or product with extreme precision
