Tata Advanced Systems Senior Engineer Interview Questions, Process, and Tips for Experienced

I have designed various tooling elements and selected materials based on their properties and application requirements.

• Designed tooling elements for manufacturing processes such as injection molding, stamping, and machining

• Selected materials based on properties such as strength, durability, and heat resistance

• Considered application requirements such as cost, weight, and environmental factors

• Examples include designing i...read more

We use a combination of CNC machining and injection molding for our manufacturing process.

• CNC machining is used for precision parts

• Injection molding is used for high volume production

• We also use 3D printing for prototyping

• Our manufacturing process is constantly evolving to improve efficiency and quality

Surface finish requirement for tooling elements is critical for achieving desired product quality.

• Surface finish affects the performance of the tooling element.

• It impacts the appearance and functionality of the final product.

• Surface finish is measured in Ra (roughness average) or Rz (roughness depth).

• The required surface finish depends on the application and material being used.

• For example, a mirror finish may be requi...read more

GD&T stands for Geometric Dimensioning and Tolerancing. It is a system of symbols and rules used to specify the geometry of mechanical parts.

• GD&T is used to ensure that parts fit together correctly and function properly.

• Some common symbols used in GD&T include concentricity, perpendicularity, and flatness.

• GD&T is often used in industries such as aerospace, automotive, and manufacturing.

• It allows for more precise commun...read more
