# Top-5 Interview Questions for Quality Engineer

A quality engineer is responsible for making sure that manufacturing processes in the industry are performed correctly using the right tools and materials within an acceptable tolerance.

Here We have a Top-5 question for you to reach your destination. Also, we have a better recommendation that helps you to become a Quality Engineer, Technical Manager or Quality Manager.

Our online course ‘The Uncommon skill of Metrology‘ helps you to become a Quality Engineer, Technical Manager, or Quality Manager. Because it has all the essential information you need to know!

## Q.1 What is Measurement?

Measurement is a Natural part of everyday life. We express daily needs in size & weight, and water and electricity are also metered.

A number of blood samples and active sub-stain in medicine also need to be precise.

I think it is impossible to describe anything without measuring it.

## Q.2 What is Tolerance in Measurement?

The tolerances on the dimensions can be specified in three ways:

### Unilateral Tolerance System

In this system, the tolerance is provided in only one direction from the basic size

For example 35.00 plus 0.2,plus 0.5

### Bilateral Tolerance system

In this system, the tolerance is split into two parts and shown on both sides of the nominal size.

For example 35.00 plus 0.2,Minus 0.5

### Limit Dimension system

In this system, the size and deviation of the part are specified by only maximum and minimum dimensions. For example 35.2 to 35.5 mm

## Q.3 What is Calibration?

Calibration is the set of operations that establish under specified conditions, the relationship between values of quantities indicated by a measuring instrument or values represented by a material measure and the corresponding values realized by standards.

## Q.4 What is a Suitable Environment Condition for Measurement?

Temperature should be 20 +/- 2 degree Celsius and Humidity should be 50 +/- 10 %

## Q.5 What is the least count of Vernier calliper and Micrometers?

Vernier Caliper is a widely used linear measurement instrument. It is used to measure linear dimensions like length, diameter, and depth.

The most common Least count of Analog Vernier Caliper is 0.02 mm. You may also find vernier least count of 0.05 mm or 0.1 mm

There are three types of Vernier Caliper

Digital , Analog and Dial Vernier Caliper

A micrometre is used to check the outside diameter of the shaft by the means of an accuracy of 0.01 mm or up to 0.001 mm.
