If you work for an engineering company, can they be considered the manufacturer if they don't physically do the machining? lets say, you make the drawings and figure out how it will be manufactured. then you purchase materials and source it out to a machining company, an NDT company and a plating company. then your company does the final inspection and quality control. Are you considered a manufacturing company? or a dealer? the machinist doesn't have access to the full technical data, only what they need in order to machine. same with all other companies involved.
