Abstract
A method for manufacturing an apparatus with a flow passage includes providing a preform apparatus with a preform flow passage. Flow area of the preform flow passage is determined to provide determined flow area data. The determined flow area data is compared to reference flow area data to provide flow area comparison data. The preform apparatus is chemical milled based on the flow area comparison data.
