MTAR Technologies QA QC Engineer Interview Questions and Answers

Cylindricity measures how close the entire surface of a cylinder is to a true cylinder, while concentricity measures how close the center points of two circles or cylinders are to being perfectly aligned.

• Cylindricity is a 3D form control that ensures the entire surface of a cylinder is within a specified tolerance zone.

• Concentricity is a 2D form control that ensures the center points of two circles or cylinders are ali...read more

Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances.

• GD&T is used to specify the allowable variations in form, size, and orientation of part features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T symbols are used on engineering drawings to communicate design requirements.

• Examples of GD&T symbols include position, concentricity, ...read more

SPC (Statistical Process Control) is a method of quality control that uses statistical methods to monitor and control a process. MSA (Measurement System Analysis) is a study that evaluates the measurement system to ensure it is reliable and accurate.

• SPC involves monitoring and controlling a process using statistical methods like control charts and process capability analysis.

• MSA evaluates the measurement system to ensu...read more
