What is CMM and its function?

A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe.

Why do we use CMM?

CMMs also allow the probe angle to be controlled to enable the measurement of complex surfaces that may otherwise be unreachable. The most common use of a CMM is to test the accuracy of a manufactured part against its original design to ensure stringent quality requirements are met and adhered to.

What is CMM in quality control?

“A coordinate measuring machine (CMM) is a device for measuring the physical geometrical characteristics of an object.” “Dimensional inspection is used in process control; its results adjust the parameters of. the manufacturing process to achieve the desired outputs.

What is CMM course?

This course is designed for inspection personnel, engineering personnel, production personnel, entry level inspectors, and those who would like to enter into the field of dimensional measurement and CMM programming.

What are types of CMM?

There are four types of CMMs, so let’s talk about them.
  • Bridge Type CMM. The first type of CMM is also the most common. …
  • Gantry Type CMM. Gantry-style CMMs are used for large products such are automobiles where the floor itself can serve as a datum. …
  • Cantilever Type CMM. Next are cantilever machines. …
  • Horizontal Arm.
