Concept Development & Design

1. Design Concepts

  

Motorized Vertical & Horizontal Travel Motorized Vertical Travel with Manual Horizontal Travel Manual Extension on Vertical Travel 2. Alignment Procedure

Concept #1 

Concept #2 

Concept #3 

Alignment Procedure     

Normalize the laser to the burner surface Put the goggles on to view laser beam Use the LabView program to move the burner until the laser is aligned on the target Move the burner in the positive vertical direction 76.2 millimeters.

Open COSMOS program provided by Velmex and set the zero position
