Automatic CNC Wood Engraving Machine

Project Title

Automatic CNC Wood Engraving Machine

Project Area of Specialization 3D/4D PrintingProject Summary

Computer Numerical Control (commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills) and 3D printers by means of a computer. Our project "Automated CNC Wood Engraving Machine" is used for making of beautiful xylography or calligraphy on wood with the help of drill automated with CNC..This is divided into two Parts

• Software
• Hardware

Software side, We design xylographic images and set toolpath and set instrustions for controlling of CNC

Hardware Side, Components are interfaced with controller. Controller ready instruction and implement on Wood.

Project Objectives

• To fullfil the demand of CNC Machine from smaller to larger scale.
• Arduino-based low cost open source hardware control system is major new development in CNC Technology
• Comprehensive construction and operation manual
• For Development of low cost educational model

• Integration with CNC based CAD tool (e.g. Ink Scape).

• Design of fully automated, CNC based wood engraving machine.

Project Implementation Method

• Reasearch for available equipment or components for this project.
• Get Full Hand On experience of creating xylographic and caligraphic design for engraving on Wood.
• Buy the Components on reasonable cost after market reseach.
• Assemble and interface the components.with controller. 
• Link the assembled hardware with Software whereas designs are ready and upload the design.
• Sart Engraving.

Benefits of the Project

• Quality innovations for the wood processing industry
• Serving as a mode of convenience for the users as well as the carpenters thereby facilitating them in every possible way.
• Least chances of error as automated implementation of design is taking place.
• Minimizing the management issues thereby providing quality in every possible way.
• Cost Efficent and Very Productive

Technical Details of Final Deliverable

Firstly, At software side, we use Inkscape for designing of xylographic Images. Then it is futher need to set the toolpath/dimmentions of that image according to wood quality. Afterwards, This image is converted to G-Code.

 Secondly, In order to upload the G-code to CNC Controller , we use grbl controller software. Where all the instrustions are sent to CNC Controller. Here we see the vector form of designed image and confirm the actual movement of CNC Machine. Then set the bit amd baud rate for communication of Hardware with Software.

Thirdly, at hardware side, we use Arduino Mega/UNO interfaced with GRBL CNC shield. This will be the major part of this project. This will be known as the Controller of CNC. As Arduino knows how to read G-Code with the help of library. So Arduino Reads the G-Code and send instructions to CNC shield in the form voltage signals. These Instrustion are used by CNC shield to control 3- stepper Motors (X ,Y and Z-axis). The CNC Dril is connected with Z-axis stepper motor frame.  

Arduino Mega/UNO is used for interfacing of hardware with Software with the help of Data Bus.
