Seminar report on the use of laser technology in machining Inconel 718 metal.
Introduction
Laser Assisted Machining (LAM) is a cutting-edge technology that has revolutionized the field of machining. Inconel 718 is a nickel-based superalloy that is known for its high strength and excellent corrosion resistance. Inconel 718 is widely used in industries such as aerospace, automotive, and oil and gas due to its superior mechanical properties. Traditional machining of Inconel 718 is challenging due to its high hardness and high-temperature strength. Laser Assisted Machining of Inconel 718 has emerged as a promising solution to overcome these challenges.
Problem Statement
Conventional machining techniques such as turning, milling, and drilling are not effective for machining Inconel 718 due to its high hardness and high-temperature strength. These conventional techniques result in high cutting forces, tool wear, and poor surface finish. As a result, the productivity and efficiency of the machining process are significantly compromised. There is an urgent need for an innovative machining technique that can enhance the machinability of Inconel 718 and improve the overall machining performance.
Existing System
The existing system for machining Inconel 718 involves traditional machining techniques such as turning, milling, and drilling. These techniques require high cutting forces and result in excessive tool wear due to the high hardness of Inconel 718. The poor machinability of Inconel 718 leads to low productivity and efficiency of the machining process. Additionally, conventional machining techniques generate a significant amount of heat, which can adversely affect the workpiece material and lead to thermal damage.
Disadvantages of Existing System
- High cutting forces
- Excessive tool wear
- Poor surface finish
- Low productivity and efficiency
- Thermal damage to workpiece material
Proposed System
The proposed system involves Laser Assisted Machining (LAM) of Inconel 718. In LAM, a high-power laser beam is used to preheat the workpiece material, followed by conventional machining using cutting tools. The laser preheating softens the workpiece material, reducing its hardness and improving its machinability. LAM enables lower cutting forces, reduced tool wear, and improved surface finish compared to conventional machining techniques. Additionally, LAM helps in reducing the heat-affected zone and minimizing thermal damage to the workpiece material.
Advantages of Proposed System
- Lower cutting forces
- Reduced tool wear
- Improved surface finish
- Enhanced machinability of Inconel 718
- Minimized thermal damage
Features of Laser Assisted Machining of Inconel 718

Conclusion
Laser Assisted Machining of Inconel 718 is a groundbreaking technology that has the potential to revolutionize the machining of nickel-based superalloys. By preheating the workpiece material with a high-power laser beam, LAM improves the machinability of Inconel 718 and enhances the overall machining performance. The advantages of LAM, such as lower cutting forces, reduced tool wear, and improved surface finish, make it a superior alternative to conventional machining techniques. The proposed system offers a promising solution to the challenges faced in machining Inconel 718 and paves the way for increased efficiency and productivity in the machining industry.
