I have need to cut miter fold v groove in 38 mm (1"1/2) thick mdf with melamine outer layer. Reality is that I have CNC with 1.5 kw spindle (ER16 collete) and no room in shop for router table. Existing bits for that large profile are all 1/2 shank size and best I can find for 1/4 shank size is 3/4" or so in depth. So I was thinking to make multiple passes with smaller v bit to achieve same effect. As a newbie I made strategy with 6 passes (see attachment) but I'm not sure is that manageable in real situation and where are pit falls. Or are there some other methods?

That method should work fine.
But I've always found miterfolding with a router bit to be problematic, as it's difficult to get a consistent thickness, and a clean cut at the tip. Melamine and laminates always seem to chip a little. I have much better results when miter folding veneered panels.
