Mechanical Design and Development Engineer Interview Questions and Answers

APQP, PPAP, MSA, SPC are quality control tools used in manufacturing.

• APQP (Advanced Product Quality Planning) is a framework used to plan and develop new products or processes.

• PPAP (Production Part Approval Process) is a set of procedures used to ensure that manufactured parts meet customer requirements.

• MSA (Measurement System Analysis) is a statistical tool used to assess the accuracy and precision of measurement systems.

• SPC (Statistical Process Control) is a method used to ...read more

There are three main types of lathe operations: facing, turning, and boring.

• Facing: Removing material from the end of a workpiece to create a flat surface.

• Turning: Removing material from the outer diameter of a workpiece to create a cylindrical shape.

• Boring: Enlarging an existing hole in a workpiece.

The stages of press tool development for a part involve designing, prototyping, testing, and refining the tool.

• Designing the press tool based on the part's specifications

• Prototyping the tool to ensure it works as intended

• Testing the tool with the part to identify any issues

• Refining the tool based on testing results and making necessary adjustments

First angle and third angle are two different methods of representing orthographic projections in engineering drawings.

• First angle projection is commonly used in Europe and Asia, where the object is placed in the first quadrant of the projection plane. The views are obtained by projecting the object onto the planes of projection.

• Third angle projection is commonly used in North America, where the object is placed in the third quadrant of the projection plane. The views are obt...read more

CAD Test on solid edge & Autocad

• Solid Edge and AutoCAD are both popular CAD software used for mechanical design and development

• Candidates may be asked to demonstrate their proficiency in creating 2D and 3D models, assemblies, and drawings

• Knowledge of features like parametric modeling, constraints, and rendering may be tested

• Ability to import and export files between different CAD software may also be evaluated

Types of cutting include abrasive cutting, chipless cutting, and shear cutting.

• Abrasive cutting involves using abrasive particles to cut materials.

• Chipless cutting involves using tools to deform materials without creating chips.

• Shear cutting involves using shear forces to cut materials.

• Examples include laser cutting, waterjet cutting, and guillotine cutting.
