Explain SPC/MSA/GD&T

Question

Accepted Answer

SPC/MSA/GD&T are quality control methods used in manufacturing.

SPC (Statistical Process Control) is a method of monitoring and controlling a process to ensure it operates within specified limits.
MSA (Measurement System Analysis) is a method of evaluating the reliability and accuracy of a measurement system.
GD&T (Geometric Dimensioning and Tolerancing) is a system of symbols and rules used to specify the size, shape, and orientation of a part.
These methods are commonly used in manufacturing to ensure quality and consistency of products.
For example, SPC can be used to monitor the temperature of a furnace during the production of steel to ensure it stays within a certain range.
MSA can be used to evaluate the accuracy of a measuring tool used to measure the length of a part.
GD&T can be used to specify the exact dimensions and tolerances of a part to ensure it fits and functions properly.
