Tool Design Engineer Interview Questions and Answers

Selecting tools for rotor machining involves considering material, geometry, coating, and application requirements.

• Material compatibility: Choose tools made from materials like carbide or high-speed steel for durability.

• Geometry: Select tool shapes (e.g., end mills, drills) that match the rotor's design and machining requirements.

• Coating: Use coated tools (e.g., TiN, TiAlN) to enhance wear resistance and reduce friction.

• Cutting parameters: Consider speed, feed rate, and depth...read more

Creating an assembly of tools involves design, selection, integration, and testing for functionality and efficiency.

• Define the purpose of the assembly and the tools required.

• Select appropriate tools based on material, size, and function.

• Design the assembly layout considering ergonomics and accessibility.

• Integrate tools ensuring compatibility and ease of use.

• Prototype the assembly and conduct tests to ensure performance.

T refers to the shape of the cutting edge in the tooling insert TNMG 160408.

• The letter T indicates a triangular shape of the cutting edge.

• The TNMG 160408 insert has a 60-degree angle on the cutting edge.

• The T shape is commonly used in turning operations on lathes.

• Other shapes for cutting edges include C, D, and V.

A mould is a tool used in manufacturing to shape and form materials. There are various types of moulds used for different purposes.

• A mould is a hollow container that is used to give shape to a material.

• It is typically made of metal or plastic and is designed to withstand high temperatures and pressures.

• Moulds are used in various industries such as automotive, aerospace, and consumer goods.

• Some common types of moulds include injection moulds, blow moulds, and compression mould...read more

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is the force applied to a material per unit area

• Strain is the resulting deformation or change in shape of the material

• Stress is measured in units of force per unit area (such as N/m^2 or Pa)

• Strain is a dimensionless quantity representing the amount of deformation relative to the original size of the material
