Describe your knowledge of CMM machines, including how they work, their components, and related ISO standards.

Question

Accepted Answer

CMM machines measure physical geometrical characteristics using a probe and are essential for quality control in manufacturing.

CMM stands for Coordinate Measuring Machine, used for measuring the physical geometrical characteristics of an object.
Components include a probe (mechanical, optical, laser, or white light), a computer for data processing, and a frame for stability.
CMMs can be manual or automated, with automated systems providing higher precision and repeatability.
They operate by moving the probe to various points on the object to collect data, which is then analyzed against CAD models.
ISO 9001 is a quality management standard that can be applied to CMM processes to ensure consistent quality control.
