Kennametal Junior Design Engineer Interview Questions and Answers

GD&T symbols are used in engineering to communicate design specifications and tolerances.

• GD&T symbols are used to specify geometric dimensions and tolerances on engineering drawings.

• They help ensure that parts are manufactured to the correct dimensions and fit together properly.

• Examples of GD&T symbols include concentricity, perpendicularity, and flatness.

• GD&T symbols are often used in conjunction with traditional dime...read more

Stress-strain curve is a graphical representation of the relationship between stress and strain in a material during a mechanical test.

• Stress-strain curve shows how a material deforms under load.

• It consists of elastic, plastic, and fracture regions.

• Heat treatment process involves heating and cooling a material to alter its properties.

• Heat treatment can change the microstructure of a material, affecting its mechanical p...read more

GD&T stands for Geometric Dimensioning and Tolerancing, a system used to define and communicate engineering tolerances.

• GD&T uses symbols to specify the allowable variations in form, size, orientation, and location of features on a part.

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

• Examples of GD&T symbols include concentricity, perpendicularity, and position.

• GD&T is commonly used in engineer...read more

Stress strain graph shows the relationship between the force applied to a material and the resulting deformation.

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

• Strain is the deformation of a material in response to stress.

• The stress-strain graph typically shows a linear elastic region, followed by a plastic region where permanent deformation occurs.

• Materials have different stress-strain curves based on their p...read more
