The NYC CNC YouTube channel focuses on all things CNC, including Fusion 360 CAD & CAM Tutorials and CNC Machining parts. As a self-taught machinists, we enjoy a positive, can-do attitude about learning how to use CAD and CAM software and how to always improve our CNC Machining skills as well as s
This video demonstrates how to use Fusion 360 with a Renishaw spindle probe on an Okuma CNC mill to measure parts, effectively turning the machine into a coordinate measuring machine (CMM). The hosts modify their Okuma post processor to enable easy part measurement within Fusion 360, showcasing the process of probing a part and comparing the results to CAD model dimensions. This technique can be a valuable tool for shops that need to verify part dimensions but don't have access to a dedicated CMM, offering a cost-effective alternative for quality control and reverse engineering applications.
Description
Being able to use Fusion with a renishaw spindle probe and a CNC machine to measure parts can be a helpful tool in the shop! It may not be as good as a CMM, but there are countless scenarios where it can still be useful! This video collaboration with @CentricIterations shows modifying our Okuma post to let Fusion 360 easily measure parts! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Links for this video Post Processor Sample: https://saundersmachineworks.com/blogs/nyc-cnc/measuring-parts-with-fusion-on-ou

Using the same machine to measure that was used to cut the part is not the best overall solution but is useful in many cases. Beware of relying on this for your only means of inspection.
Nice work! Thanks Ethan and John.
We do this at work on our DMG dmu 50s. The machine checks the parts dimensions that can't be measured with conventional means and outputs to an Excel file and shows in green or red which dimensions are in/out. Then we can make the appropriate offsets to get near perfect parts.
first part i machined using cam was based on one of your videos back in 2018. after 7 yrs and I am far ahead in my carrier I still appreciate this amazing channel. Thank you
What sucks is that all the measurements taken with the probe in the machine are dependent on how often and when you last calibrated the probe. Would be nice to automate the calibration. Probe diameter is easy but run out is a pain, some of this can be checked vs a known diameter with a variable for
