Question 1

What does 'Design for Assembly' (DFA) focus on in product engineering?

Accepted Answer

Reducing the number of assembly steps and part count to simplify and speed up the assembly process

Answer

DFA systematically reduces the number of parts and simplifies joining methods to minimize assembly time, errors, and labor costs during production.

Question 2

In engineering change management, what is an Engineering Change Order (ECO)?

Accepted Answer

A formal document that authorizes and records a revision to a product design or specification

Answer

An ECO is the formal mechanism for controlling, documenting, and implementing approved changes to product designs, ensuring traceability and coordination across manufacturing and supply chain.

Question 3

Which analysis method is used during product design to proactively identify potential failure modes and their effects on product function?

Accepted Answer

Failure Mode and Effects Analysis (FMEA)

Answer

FMEA systematically examines each potential failure mode of a design or process, evaluating its severity, occurrence probability, and detectability to prioritize risk mitigation actions.

Question 4

What is the function of a 'datum' in GD&T on a manufacturing engineering drawing?

Accepted Answer

It defines a theoretically exact reference plane, axis, or point from which measurements and tolerances are made

Answer

A datum is a theoretically perfect geometric reference used in GD&T to establish the origin and orientation from which part dimensions and tolerances are measured and controlled.

Question 5

What does 'Design for Six Sigma' (DFSS) aim to achieve when applied to new product development?

Accepted Answer

Designing products and processes from the outset to meet Six Sigma quality levels, minimizing defects before production begins

Answer

DFSS proactively integrates Six Sigma quality principles into product and process design, aiming to achieve near-defect-free performance from initial production rather than correcting problems later.
