Laser Engraver and Digital Die Cutting Machine

Project Title

Project Area of Specialization

Mechatronics Engineering

Project Summary

Die cutting or subtractive manufacturing is a process of cutting two dimensional solid objects from a digital file using simulation software. Die cutting allows manufacturers to build sleek, stylish products without sacrificing efficiency or affordability. Lasser cutting allows manufacturers to create cuts with accuracies of ±0.005% a level of accuracy not previously seen. Die cutting continues to grow in prominence as an essential method of fabricating products that consumers use daily. Die cutting is the opposite of additive manufacturing which is the object is created by laying down successive layers of material until the object is created.

Project Objectives

To digitize die cutting process.
To develop customized die cutting at reduced cost.
To increase knowledge on cutting & characterizations of multiple dimensional digital die cutting tools.
To boost local die cutting industry.
To make it available in rural side of country.
To conduct mechanical structural sub system test and calibration.
To conduct electronic sub system test and calibration.
To conduct hardware sub system test and calibration.

Project Implementation Method

A Die cutting machine remove extra material form any sheet. This process is done by many ways but using laser cutter for small operation comes out to be the best option. The nozzle of the cutter move too and fro and entirely controlled by computer. The laser cutter can cut and engrave any material of any thickness. But it is best for the usage of material thickness up to 5mm. if thickness of material is more than 5mm then we have some other cutting option like plasma, milling, and water jet cutting etc. The Digital Die-cutting machine operation starts with collecting the data from the programming that extract from the computer-aided design (CAD) and computer-aided manufacturing (CAM). The programs produce the computer file and then will extract the command to operate the machine. The program will be transferred via post-processor and then be loaded into the CNC machine to start the machining.

Benefits of the Project

Reducing human interference.
Increasing efficacy and preciseness.
Reduce wastage.
Occupy less space than manual Die cutter.
Neat and clean atmosphere.
Making final product sharper
Reduce labor cost and increase production.
Unlimited Shaped and Geometry of choice.
Edges are clean with no burn and dust formation.
It allows us to cut crisp, clear shapes straight from substrates.
No dependency on industry component level
No material deformation due to contactless processing.
Cutting of material of various thickness and combinations in one go.
No need of a physical reference die.
