The problem with using tape to affix raw bar or sheet stock to a fixture plate is the raw material is subject variations in flatness and thickness. This is true even of MIC-6 tooling plate, even though it is Blanchard ground. The piece of bar stock shown in this video fortunately does not suffer from bow or twist, else it could be dislodged during machining. However, it is a best practice to secure the material by using a low-profile side-clamping solution and flatten the top surface if tape will be used. It is very annoying (and potentially costly) to have the workpiece thrown free of the table.
Is mankind doomed? Do you ever just sit there and watch toolpaths and think "How the hell did it come up with that!"... but you won't be able to fault it. It's all a bit scary! 😱 😜 I love what you do, thanks for the videos. L & S. 👍
I am really curious if you have done anything else to your PrintNC in order to have such stability and good surface finishes, I know speeds n feeds have a lot to do with this but still, your frame appears very rigid and minimal vibrations. I am interested in building my own PrintNC, but I think I will be mostrly using it for wood while learning.
