What does a CMM do?
You are here to find out what does a cmm do? Well… A CMM or coordinated measuring machine is used to measure the physical geometrical characteristics of an object. By combining the use of a stable platform, measuring probe and data collecting software the machine takes preset measurements from an object or part and collates the data for analysis on a computer. It replaces the work of hand measuring tools like callipers or micrometers. Rather than having to manually take the measurements, which could then include an element of human error, and then collect and input data this machine does all the hard work for you. With an accurate setup you can rely on the data taken to produce plans, designs and confidently invest in a new part or assembly lines based on the information.
This removes the time consuming process of taking multiple measurements and the element of human error. It is even capable of telling you how ‘circular’ a hole is by taking various measurements and automatically comparing them to provide information about the object’s form. By reducing the time required to take and analyse the information, cost saving efficiencies are subsequently introduced to the manufacturing process. By shortening the time between design, quality control and build, as well as reducing the margin for error, you will inevitably save money.
What else can I do with a CMM?
There is also the opportunity to do more with your data. A coordinated measuring machine allows for measurements to be directly compared with CAD models. By coordinating the software on your computer, the data taken and the correlating design data can be easily compared to check for anomalies or inaccuracies in the build process. Early detection can save both time and money in the manufacturing process. A CMM is able to provide rich data for accurate inspection by the controller and product development, design or quality control team.
A CMM does far more than simply measure. By using the measuring tool to streamline the build process, improve efficiency, remove the element of human error and even develop designs for the product, a coordinated measuring machine can speed up the entire manufacturing process as well as have a positive impact on the reliability, efficiency and economy of the project.
