For every manufacturing process, accurate geometric and physical dimensions are important. There are two methods people use for such purpose. One is the conventional method that involves the use of measuring hand tools or optical comparators. However, these tools require expertise and are open to lots of errors. The other is the use of a CMM machine.

CMM machine stands for Coordinate Measuring Machine. It is a tool that can measure the dimensions of a machine/tool parts using coordinate technology. The dimension open to measurements include the height, width, and depth in the X, Y, and Z-axis. Depending on the CMM machine’s sophistication, you can measure the target and record the measured data.

The traditional method of measuring parts has many limitations. For example, it requires experience and skill from the operator inspecting the parts. If this is not well represented, it can lead to the supply of parts that are not good enough.

Another reason is the sophistication of the parts that are produced in this century. Development in the technological sector has led to the development of more complex parts. Therefore, a CMM machine is better used for the process.

The CMM machine has the speed and accuracy to repeatably measure parts better than the traditional method. It also increases productivity while reducing the tendency of having errors in the measuring process. The bottom line is that knowing what a CMM machine is, why you need them, and using them will save time, money and improve your company’s reputation and image.
