why do you need to track the number of a components in which a metal raw material can be cut into?
if that is needed, then you have to have a separate order for this, as explained earlier.
if these intermediate components are getting completely consumed to produce the finished material, then you will not have anything left, hence I do not see a need to keep track of that based on the given information.
I do not foresee any issue with costing, except you still have something in mind which is not yet written here.
