This may not be the right forum for this question, but has anyone built cabinets where the parts were CNC machined with blind dados?
Here is a case going together with this method. If you have, tell me about method. Glues? Applicators? Fasteners? Tools?
We are considering a switch in method, from dowel-plus-confirmat-screw joinery, to this, and wondering what will happen.

You might get better answers in the Fine Woodworking forum, but you would also take a lot of gas about particle board. (That IS particle board, isn't it?)
I don't do production work and I've never used blind dados, but it looks like glue, assemble, check for square, and clamp would do the job. If you're working with several pieces, some extra hands during assembly may be necessary.
I can't answer your question, but have one of my own. It seems to me that the dados in your pic actually weaken the weight-carrying capacity of the shelves. I would think that leaving the shelves at full thickness and recessing them into wider dados would make them stronger. The first inch at the front of the shelf could remain much as you have it so the Appearance would not be affected.
My instinct tells me that reducing the shelf thickness by half has a more detrimental effect on strength than doubling the width of the dados because of the vertical configuration of the sides of the carcass.
Most places that I've seen using MDF and dados, use a heat curing glue that doesn't swell the MDF and make assembly a PITA. Stuff usually cures in 30 minutes so the carcases can be handled. Pops right off the Melamine too.
Ayup. It is actually Radio Frequency cured IIRC. ZAP!
That's right. Knew a guy that worked that, and had trouble with his pacemaker.....
