Sansera Engineering Quality Engineer Interview Questions and Answers

Quality is meeting or exceeding customer expectations. Various gauges are used to measure quality. The unit of air pressure is typically measured in psi or pascals.

• Quality is the degree to which a product or service meets or exceeds customer expectations.

• Various gauges such as calipers, micrometers, and CMMs are used to measure quality in manufacturing processes.

• The unit of air pressure is typically measured in pounds per square inch (psi) or pascals (Pa).

8D is a problem-solving methodology used in the industry to identify, correct, and prevent recurring problems.

• 8D stands for Eight Disciplines and is a structured problem-solving approach.

• It involves a team-based approach to identify the root cause of a problem, implement corrective actions, and prevent recurrence.

• 8D is commonly used in industries such as automotive, manufacturing, and aerospace.

• The process includes steps like forming a team, defining the problem, implementing...read more

Various types of scales are used in quality engineering depending on the application.

• Common types include digital scales, balance scales, and platform scales.

• Scales may be used to measure weight, force, torque, or pressure.

• Accuracy and precision are important factors to consider when selecting a scale.

• Calibration and maintenance are necessary to ensure accurate measurements.

• Scales may be used in industries such as manufacturing, food production, and pharmaceuticals.

1 micron is equal to 0.001 mm.

• 1 micron = 0.001 mm

• Micron is a unit of length equal to one millionth of a meter

• Millimeter is a unit of length equal to one thousandth of a meter

Least count is the smallest measurement that can be made with an instrument.

• It is the smallest value that can be measured with an instrument.

• It is determined by the precision of the instrument.

• For example, the least count of a ruler with millimeter markings is 1 mm.

• It is important to consider the least count when taking measurements to ensure accuracy.

Tolerance is the acceptable range of variation in a measurement or dimension.

• Tolerance is the maximum and minimum limits within which a product or process must operate.

• It ensures that parts fit together properly and function correctly.

• Tolerance is often specified in engineering drawings using symbols like +0.1/-0.1mm.

• For example, a hole may have a diameter tolerance of +/- 0.05mm.
