Cmm Quality Engineer Interview Questions and Answers

Profile tolerance of line or surface can be determined using geometric dimensioning and tolerancing (GD&T) principles.

• Profile tolerance defines a uniform boundary around a feature within which the true profile must lie.

• It is specified using a tolerance zone that controls the form, size, and orientation of the feature.

• Profile tolerance can be applied to both lines and surfaces in engineering drawings.

• GD&T symbols like profile of a line (⌒) or profile of a surface (⌓) are used ...read more

GD&T stands for Geometric Dimensioning and Tolerancing. Concentricity is a type of tolerance that controls the central axis of a cylindrical feature. Position tolerance determines the allowable deviation of a feature from its true position.

Performing addition and subtraction of complex numbers involves adding or subtracting the real and imaginary parts separately.

• To add two complex numbers, add their real parts and imaginary parts separately.

• To subtract two complex numbers, subtract their real parts and imaginary parts separately.

• Example: (3 + 2i) + (1 - 4i) = (3 + 1) + (2 - 4)i = 4 - 2i

• Example: (5 - 3i) - (2 + 7i) = (5 - 2) + (-3 - 7)i = 3 - 10i
