What is a Coordinate-measuring machine?
A 3D Coordinate-Measuring Machine (CMM) is a precision device used to measure the geometry of physical objects by detecting specific points on their surfaces with a probe. These machines are crucial in industries like aerospace and automotive for ensuring parts meet exact specifications.
CMMs use probes, which can be contact or non-contact, to capture data points on an object’s surface. The probe’s movement is either manually controlled or automated via Direct Computer Control (DCC), enhancing accuracy and efficiency. Operating within a three-dimensional XYZ coordinate system, CMMs can measure complex surfaces, especially when equipped with adjustable probe angles.
There are various types of CMMs, such as bridge, gantry or small portable models, each suited to different measurement tasks. Modern CMMs also incorporate advanced software that processes measurement data, providing real-time feedback and detailed analysis, ensuring high precision in manufacturing processes.
The benefits of using a teaching and programming CMM include the quick setup on a manual machine while retaining the advantages of automation. Most modern CMM measuring software, such as Aberlink or Polyworks, features a ‘program by teaching’ mode. As you measure the required features, the CMM software records the data and simultaneously builds the foundation for a program.
Whether you operate the machine manually, as with the C4, or use a joystick to move from feature to feature, there isn’t much speed advantage for the manual machine over the DCC. However, if your goal is to use the CMM in a workshop setting where it’s accessible to everyone, a manually driven probe will be easier to handle.
Once you’ve taken the measurements and collected the data, you’re ready to proceed. However, if you want to verify your work, you’ll need to remeasure the part. When it comes to measuring a second part, the existing program is already in place, allowing you to reuse it. At this point, the DCC becomes a more efficient solution, as it allows you to remeasure all features with the push of a button.
