Hyoseong Electric Interview Questions and Answers

Q1. What are MMC and LMC, Explain With Example?
Ans. 
MMC stands for Maximum Material Condition and LMC stands for Least Material Condition. They are used in Geometric Dimensioning and Tolerancing (GD&T) to specify the maximum and minimum limits of a part's dimensions.
• MMC is the condition where a part contains the maximum amount of material within the specified limits.

• LMC is the condition where a part contains the least amount of material within the specified limits.

Q2. What is Layout Inspection ?
Ans. 
Layout inspection is a quality control process to verify dimensions, tolerances, and alignment of components or products.
• Ensures components or products are manufactured according to design specifications

• Involves measuring dimensions, angles, and alignments using tools like calipers, micrometers, and CMM machines

• Helps identify any deviations from the design that may affect product functionality or performance

Q3. What is GD&T. What are the Symbols of GD&T.
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing. It is a system for defining and communicating engineering tolerances.
• GD&T is used to specify the allowable variations in form, size, and orientation of part features.

• Some common symbols used in GD&T include: Ø for diameter, ⌀ for circular runout, ⊥ for perpendicularity, and ∠ for angularity.

• GD&T helps ensure that parts fit together properly and fun...read more
