Tool Design Engineer Interview Questions and Answers

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

Elastic properties refer to the ability of a material to deform under stress and return to its original shape when the stress is removed.

• Elastic properties include Young's modulus, shear modulus, and Poisson's ratio.

• Young's modulus measures the stiffness of a material in tension or compression.

• Shear modulus measures the stiffness of a material in shear.

• Poisson's ratio describes the ratio of lateral strain to axial strain when a material is stretched or compressed.

• Materials wi...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
