Characteristics of Laser Aided Direct Metal Deposition Process for Tool Steel
공구강을 이용한 레이저 직접 금속조형 공정의 적층 특성
Abstract
Laser aided direct metal deposition (LADMD) process offers the ability to make a metal component directly from 3-D CAD dimensions. A 3-D object can be formed by repeating laser cladding layer by layer. The key of the build-up mechanism is the effective control of powder delivery and laser power to be irradiated into the melt-pool. A feedback control system using optical sensors is introduced to control laser power and powder mass flow rate. Using H13 tool steel and
