The additive manufacturing method and additive manufacturing apparatus for performing additive manufacturing by moving a processing unit that emits laser while supplying metal powder

摘要

The additive fabrication processing method includes: a setting step of setting a speed command value indicating the speed of a processing head, and a metal powder supply amount command value indicating a supply amount of the metal powder corresponding to the speed command value; an acquisition step of acquiring both a speed indicating the speed of the processing head at which actually moving and an actual distance indicating a distance actually between the processing head and a surface on which spraying metal powder; and a supply amount calculation step of calculating a metal powder supply amount by correcting the metal powder supply amount command value based on the speed and the actual distance, so that a program command route and a processed surface match.
