Why 3D scan? - full field data set
One of the major advantages of 3D scanning is it creates “full field data set” or sometime it’s called “digital twin”. The CMM has done a great job when it comes to collecting just enough data accurately and reliably for dimensional inspection purposes. What the CMM is focused on is to verify pre-defined features/dimensions to determine if parts are good or bad. However, when things go wrong and more information is needed to further analyze the root causes it takes a lot of efforts and tedious work to get enough useful information.
3D Scanning or Tactile Probing?
3D scanning technologies have been rapidly developing in the last 10 years and widely used in manufacturing industries for Metrology purposes. Although people get used to seeing various scanning systems and most time have good understanding on what this technology can bring to you, many common questions still remain such as “should I choose a 3D scanner or a CMM?”, “can I use the 3D scanner to totally replace my CMM?”, etc.
