Abstract

Laser Beam Micromachining (LBMM) is proven technique in micromachining materials with such extreme properties because it is non-contact, rapid and flexible process having high material removal efficiency with low power requirement and almost zero tool wear. LBMM is an extremely versatile ultraprecision manufacturing process because of its ability to machine wide range of advanced materials. While most commercial laser machining systems are capable of machining at macroscale, laser micromachining tends to be challenging and expensive. In this research a team of three undergraduate students are working towards designing and fabricating a low cost LBMM system that can machine materials at micron scale. The design of the laser machining system relies on several design considerations, including a finite element analysis of the thermodynamic effects present on the cutting medium, as well as the control of the cutting head, design of the frame, enclosure and laser head cutting structure. The frame, enclosure, stage, laser enclosure, control mechanisms and support structure are designed and assembled to be able to cut thin materials such as composites, wood, and plastics. Additionally, the system has the ability to engrave metals. This design is done according to mathematical models of laser beam micromachining process. The design is performed using commercial CAD package – Solidworks followed by a structural design analysis. This project is important for use of the students at CSUF, as access to a laser machining machine is limited. This machining system would promote learning in cutting edge advanced manufacturing technologies.
