Using OdooMRP modules "product configurator" and generic boms with templates could solve part of your problems. But the "cutting" thing would be not solved yet. 

You can find the modules in OCA community branches or OdooMRP project in Github. Modules has been built for V8 and we did not start the task of migrating them but maybe they could be usefull if you decide to start with.

You can also see the youtube odoomrp channel where several videos has been published about product configurator and generic boms.

Wishing this helps:

Hi All,
I am implementing odoo v9 in a furniture factory.
There are a couple of challenges i am facing.

Hopefully somebody has some experience/advice with the following

1) Cutting stock problem / Guillotine cut (
When i define for example melamine furniture in MRP, the furniture is made up of certain pieces of melamine which i can put in a BOM.

Then when a order is placed, at one moment we want to know how many sheets of melamine we need to buy. (can be any combination of furniture and amount)
I can define each piece as a m2, but at the end this is inaccurate.(as well as plain vs wood grain direction).

So in a perfect world, accepting the SO would loop over the Boms needed  to determine the optimal cuts (and thus sheets necessary) for that order. then puts a PO for those sheets.
At the same time when it has generated that cuts, it places the output in a file that can be used in the CNC woodcutting machines (workstation).

2) Variable Material / Shared/multiple BoMs
Another challenge is on how to define all the furniture within odoo.
All the pieces of the furniture can be defined, except their material. (can be mdf+formica, melamine, mdf+veneer, mdf-painted, polyurethane) 
one option is to use (nested) boms.
the issue with that is that i need to define to manufacture all the pieces and all their variations. We have quite some suppliers so we definitively dont want to put all their melamine/formicas as a variant for each piece. (maintaining it would be a pain..)

I have looked into orderline variables, but that still needs a separate bom for each variable.
would have been ok if you were able to use multiple boms per product. A base-bom vor all the variants, and an additional variant specific BoM 

Any thoughts on this?
