Re: Milli a new composite mill kit
CSA - is that what Slocum used in the concrete shear damper system?
Any literature on CSA use for machine tool frames? Particularly as molded vs filling steel tubes/forms.
I have been thinking about the use of styrofoam balls in epoxy granite for ages. Haven't found any literature / testing.
Big balls (measured in tens of centimetres) arranged by some sort of wire grid / spacers OR small balls (measured in mm) chucked into the mix?
For my design, weight and epoxy volume (major cost) are important considerations. Section size can easily go up for base and columns. Only saddle has major size constraints.
From my untrained FEA, few larger diagrid members worked nearly as well as many smaller. Much easier to mold / form fewer larger ones.
