stress relieving cnc frame

[routercnc]

Hi Farzad,

I'm not aware that anyone on the forum has used the Vibration Stress Relief process, but I could be wrong. There is an abstract to an article here which suggests it gives similar results to Thermal Stress Relief: https://journals.sagepub.com/doi/10....44089241286271

Another option is just to build it as it is and monitor the squareness periodically and then shim the column to base joint as required if anything moves?

For the design it sounds like the materials have already been built but I would have considered extending the side plates on the column down to the clamping interface plates. Same on the lower base section - extending the side plates back to the interface joint plates. This way there is no real change of section as you transition from the base to the column. But I'm sure it will still all work as a milling machine as there are large sections and thicknesses used in the design.

Good luck with it!
