Madras Engineering Industries Interview Questions and Answers

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.

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

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

Selecting the right instrument for dimensional inspection involves considering the accuracy, precision, and type of measurement needed.

• Identify the specific dimensions and tolerances that need to be measured

• Consider the accuracy and precision required for the inspection

• Choose the appropriate instrument based on the type of measurement (e.g. calipers for linear measurements, micrometers for precise measurements)

• Ensure t...read more

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.

• Symbols used in GD&T include: concentricity, position, profile, runout, perpendicularity, parallelism, etc.

• GD&T helps ensure parts are manufactured to the correct dimensions and tolera

Selecting the right instrument for dimensional inspection involves considering accuracy, precision, type of measurement, and calibration.

• Understand the specific requirements of the component being inspected

• Consider the accuracy and precision needed for the measurements

• Choose the appropriate type of instrument (e.g. calipers, micrometers, CMM)

• Ensure the instrument is properly calibrated before use

• Verify the instrument's...read more
