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

• GD&T includes symbols, rules, and definitions used to define the geometry of mechanical parts and assemblies.

• Types of GD&T include position, concentricity, parallelism, perpendicularity, flatness, circularity, and more.

• Each type of GD&T symbol has a specific meaning and is used to control different aspects of...read more

PFMEA stands for Process Failure Mode and Effects Analysis, a structured approach to identifying and prioritizing potential failure modes in a process.

• PFMEA is a proactive tool used to prevent defects by identifying potential failure modes and their effects on processes.

• It involves ranking failure modes based on their severity, occurrence, and detection, to prioritize improvement efforts.

• PFMEA helps in developing actio...read more

Cp measures the potential capability of a process, while Cpk measures the actual capability of a process.

• Cp is used to assess how well a process can meet the specifications, while Cpk also takes into account the process centering.

• Cp only considers the spread of data, while Cpk considers both spread and centering.

• Cp should be greater than or equal to 1 for a process to be considered capable, while Cpk should be greater ...read more

Gauge R&R (Repeatability and Reproducibility) is a statistical tool used to assess the measurement system variation in a process.

• Gauge R&R helps determine how much of the variation in a process is due to the measurement system itself.

• It involves conducting a study where multiple operators measure the same parts using the same gauge to assess repeatability and reproducibility.

• The goal is to ensure that the measurement s...read more
