I am not sure if this is the right forum for this question. I am designing a doll house for my daughter. I have a couple questions about tolerances with CNC and plywood wood since I am new to CNC. I would always have to account for shrinkage, extrusion and whatnot with 3d printing, but I am not sure if it is as necessary with milling.
some of the pieces are too big for my machines foot print. To compensate, I designed two pieces with a puzzle piece type joint that will be glued together. I want a tight fit since the glued up pieces should glue up form a single part. Do I need a bit of tolerance between the two joints or can the be designed as exact fits?
This one is not as important however, still looking for advise here as well. Most of the other parts have slot and tab joints. Do I need tolerances here as well or would it be sufficient to have the exact same dimensions I.E. slot is .25 x 1 and tab is .25 x 1. or should I design the tab as .2 x .9? These do not have to be such a tight fit since I do not expect the glued up piece to function as if it was a single piece.
