Aequs Production & Quality Engineer Interview Questions, Process, and Tips

Parallity and perpendicularity can be checked using precision measuring tools and techniques.

• Use precision measuring tools such as calipers, micrometers, or height gauges to measure the dimensions of the object.

• For checking parallelity, measure the distance between two parallel surfaces at multiple points and ensure they are consistent.

• For checking perpendicularity, measure the angle between two surfaces that should be...read more

A lever gauge is used to measure the thickness of objects by applying pressure with a lever arm.

• Place the object to be measured between the anvils of the lever gauge.

• Use the lever arm to apply pressure on the object until it is firmly held between the anvils.

• Read the measurement displayed on the gauge to determine the thickness of the object.

• Ensure the gauge is calibrated properly for accurate measurements.

Cylindricity refers to how closely a cylinder's surface conforms to a perfect cylinder, while circularity refers to how closely a circle's boundary conforms to a perfect circle.

• Cylindricity is a 3D form tolerance that controls the overall form of a cylinder, including straightness, roundness, and taper.

• Circularity is a 2D form tolerance that controls the roundness of a circle, ensuring that all points on the circle are...read more

8D problem-solving method is a structured approach to identify, correct, and prevent recurring problems.

• 1. Define the problem: Clearly state the issue and its impact.

• 2. Establish a team: Form a cross-functional team to work on the problem.

• 3. Develop an interim containment action: Implement a temporary solution to prevent further issues.

• 4. Identify the root cause: Use tools like 5 Whys to determine the underlying cause.

• ...read more

RPN in SPC stands for Risk Priority Number, a calculation used in Six Sigma to prioritize potential failure modes based on severity, occurrence, and detection.

• RPN is calculated by multiplying the severity, occurrence, and detection ratings of a potential failure mode.

• It helps in identifying high-risk failure modes that need immediate attention in order to improve quality.

• For example, if a failure mode has a severity ra...read more
