CWRU EMAE 398 Capstone Project

1. WAAM 3D
printer
Project Advisor: John lewandowski and Vishnushankar Viraliyur
Group Members: Óscar Javier Enériz Bueno, Boxuan Song

2. Project Overview and Deliverables
● WAAM technology to build 3D printer
○ Wire Arc Additive Manufacturing
● Successfully build the 3D printer
○ Mechanical
○ Electrical
○ Print one part

3. Requirements Calculations ( Cutting forces)
Power = Area of cut * Specific force of the material*Table speed =
Axial depth of the cut*Radial depth of the cut*Specific force of the material*Table speed
Cutting force required = Power / Table speed
Weight = Cutting force / 9.814
Milling surface = Chip load average * Length of the cutting edge
Cutting force required = Milling surface * Specific force
Weight = Cutting force / 9.814
Method 1:
Method 2:
