Tool Designer Interview Questions and Answers

GD&T is a system for defining and communicating engineering tolerances using symbols, allowing for precise manufacturing and inspection.

• GD&T uses symbols to specify geometric characteristics of parts, such as flatness, perpendicularity, and concentricity.

• It helps ensure parts are manufactured and inspected accurately, leading to better quality and interchangeability.

• GD&T is commonly used in industries like aerospace, automotive, and manufacturing.

• Understanding GD&T is essenti...read more

I am proficient in using CAD software such as AutoCAD, SolidWorks, and CATIA for over 5 years.

• Proficient in AutoCAD, SolidWorks, and CATIA

• Over 5 years of experience with CAD software

I prefer using SolidWorks for designing as it is user-friendly, versatile, and widely used in the industry.

• SolidWorks is user-friendly and easy to learn for beginners

• It offers a wide range of tools and features for designing complex tools and parts

• SolidWorks is widely used in the industry, making it easier to collaborate with others and share files

• It has a large online community for support and resources

• Other popular designing software include AutoCAD, CATIA, and Siemens NX

Types of resins used in manufacturing include epoxy, polyester, polyurethane, and silicone.

• Epoxy resin is commonly used for adhesives, coatings, and composite materials.

• Polyester resin is often used in fiberglass reinforced plastics.

• Polyurethane resin is known for its flexibility and durability, used in coatings, adhesives, and foams.

• Silicone resin is heat resistant and used in sealants, adhesives, and electrical insulation.

The 3-2-1 principle in design refers to the minimum number of reference points needed to properly locate a part for machining or assembly.

• 3 points are used to position the part in the X, Y, and Z axes

• 2 points are used to prevent rotation around the X and Y axes

• 1 point is used to prevent movement along the Z axis

• Example: Using 3 pins to position a part on a fixture for machining

Tolerance is the allowable variation in a dimension or property of a part or product.

• Tolerance is the difference between the maximum and minimum limits of a dimension or property.

• It ensures that parts fit together properly and function as intended.

• Tolerance can be specified as a plus or minus value, or as a range.

• Examples of tolerances include size, weight, and temperature.

• Tolerance can be affected by factors such as manufacturing processes and materials used.

BOM stands for Bill of Materials, which is a comprehensive list of all the materials, parts, and components required to manufacture a product.

• BOM is used in manufacturing to ensure that all necessary components are available for production.

• It includes information such as part numbers, quantities, and descriptions.

• BOM can be used for both finished products and sub-assemblies.

• It is an essential document for production planning and inventory management.

• Examples of industries tha...read more
