10+ Tata Motors Quality Engineer Interview Questions and Answers

To draw an isometric view from an orthographic drawing.

• Identify the front, top, and right side views from the orthographic drawing.

• Draw the isometric axes at 120 degrees to each other.

• Project the points from the front, top, and right side views onto the isometric axes.

• Connect the projected points to form the isometric view.

A six stroke engine is an internal combustion engine that has six strokes in its cycle instead of the traditional four strokes.

• The six stroke engine was developed to improve fuel efficiency and reduce emissions.

• It adds an additional power and exhaust stroke to the traditional four stroke cycle.

• The additional strokes are achieved by adding a second set of valves and an additional cylinder.

• The six stroke engine can be configured to run on various fuels, including gasoline, dies...read more

Use visual inspection, cross-cut test, and weight measurement to check powder coating thickness without a thickness meter.

• Perform visual inspection to check for any uneven coating or areas with no coating

• Conduct a cross-cut test by making a small incision in the coating and checking the layers

• Measure the weight of the coated object before and after coating to estimate the thickness

• Compare the appearance and weight of the coating with a known standard for reference

Use visual and tactile inspection methods to check roughness without a roughness tester machine.

• Use visual inspection to look for uneven surfaces, scratches, or irregularities

• Use tactile inspection by running your fingers over the surface to feel for roughness

• Compare the surface in question with a known standard of roughness for reference

• Use a magnifying glass to inspect the surface closely for any imperfections

The dial gauge pressure unit is a unit of measurement used to quantify pressure readings on a dial gauge.

• The dial gauge pressure unit is typically measured in pounds per square inch (psi)

• Other common units include bar, kilopascal (kPa), and atmospheres (atm)

• The specific unit used will depend on the type of dial gauge being used

• For example, a tire pressure gauge may display readings in psi, while a pressure cooker gauge may use kPa

Waner clipare listening is a term used in quality engineering to describe the process of comparing two similar items or processes to identify differences.

• Waner clipare listening involves carefully analyzing two items or processes to identify any discrepancies or variations.

• This comparison is essential in quality engineering to ensure consistency and identify areas for improvement.

• Examples of waner clipare listening include comparing two production lines to identify difference...read more

Yes, the heart of a diesel engine is the fuel injection system.

• The fuel injection system is responsible for delivering fuel into the combustion chamber at the right time and in the right amount.

• It plays a crucial role in the performance and efficiency of the engine.

• Examples of fuel injection systems include common rail, direct injection, and unit injector systems.

Runout measures the total indicator reading (TIR) of a rotating part, while concentricity measures the center point of a feature relative to its axis.

• Runout is the total indicator reading (TIR) of a rotating part, indicating how much the part deviates from a true circle when rotated.

• Concentricity measures the center point of a feature relative to its axis, ensuring that the feature is centered around a common axis.

• Runout is typically used for parts with circular features like...read more

Macro miter listening is a technique used in quality engineering to identify and address issues by actively listening to feedback and observations from a wide range of sources.

• Macro miter listening involves gathering feedback and observations from various stakeholders including customers, employees, and suppliers.

• It focuses on identifying patterns and trends in the feedback to address underlying issues and improve overall quality.

• Examples of macro miter listening techniques i...read more

UTM test of weld parts without UTM machine

• Use destructive testing methods like bend test, tensile test, or hardness test to evaluate weld quality

• Visual inspection can also be used to assess weld integrity

• Ultrasonic testing can be utilized to detect flaws in the weld without UTM machine

A carburettor is a device in an internal combustion engine that mixes air with a fine spray of liquid fuel.

• Carburettors are used in older vehicles to control the air-fuel mixture for combustion

• They work by using the engine's vacuum to draw fuel into the engine

• Carburettors have been largely replaced by fuel injection systems in modern vehicles

Quality is the measure of excellence or superiority of a product or service.

• Quality is meeting or exceeding customer expectations

• It involves consistency and reliability in performance

• Quality is achieved through continuous improvement and adherence to standards

• Examples: defect-free products, high customer satisfaction, on-time delivery
