After getting bit hard by the CNC bug after receiving my Nomad it wasn’t long until I decided to scale up a bit. I purchased a Tormach PCNC770 in April and then became obsessed with fixture plates, vacuum chucks and various other workholding solutions. To that end, I decided to spend some time designing a modular fixture plate for the Nomad.
You can see the general idea in the following photo album: http://imgur.com/a/1hY3K
I’m curious as to what people think about it in general as well as the overall level of interest in the idea. I’ve ordered the taps and reams and once they arrive I plan to cut one out of a mic-6 aluminum plate I have on hand.
Trade offs with something like this is the cost, loss of a 1/2" of your “Z” axis and the need to use a more advanced CAM solution so that you can add your fixtures to avoid collisions. One other problem is the lack of a truly accurate way to set the work coordinate on machines like our Nomads to prevent cutting into the plate. I have a Haimer New Generation 3D-Sensor for my Tormach and it is a great piece of hardware … they or some other company needs to develop a smaller/affordable solution to cater to this market. Free business idea!
I also think it would be quite interesting to have a public model repository of various clamps/widgets/whatevers that people want to share as they come up with solutions to various workholding problems.
Everything was designed and CAM’d in Autodesk Fusion360 which I highly recommend if you haven’t checked it out already.
Thanks for reading and I look forward to hearing everyone’s thoughts.
