CNC router is a computer-controlled cutting machine related to the hand-held router used for cutting various hard materials, such as wood, composites, aluminium, steel, plastics, glass, and foams. It typically produces consistent and high-quality work and improves factory productivity. Automation and precision are the key benefits of CNC router tables.A CNC router can reduce waste, the frequency of errors, and the time the finished product takes to get to market. Below is an image of how a CNC router looks like :

Steps followed :

1. I used "Aspire" software for modelling for the CNC router The basic UI looks something as follows :

2. We then imported an arrow DoD model from Solidworks and saved it as .dxf file :

3. Origin has to be set in the drawing for the orientation of CNC.

4. Disjoint parts in the drawing has to be joined. Select Edit Objects -> Open vectors -> Join.

5. Select 17mm as thickness ( of the sheet ) in material setup.

6. Select the sketch and then go to Toolpath Operation -> Profile Toolpath. Give the dimensions as : Start Depth – 0mm, Cut Depth – 17mm.

7. In machine vector, choose where will the drill make the cut- inside, on the line or outside.

8. 'Tabs' are added with a thickness of 2mm and length 6 mm. Tabs are given to prevent the cut piece from moving away during the cutting process. Adding tabs will leave uncut areas with the thickness provided which can be later removed by chisel.

9. After the required dimensions are given, Click on 'Calculate'.

10. Order of the tasks can be arranged as engraving is generally done first and profiling, later.

11. Select Post Processor- WINCNC GCode (mm) (*.tap) and save the toolpath. Copy the files to pendrive and connect to the Controller.

>

12. Click Run/Pause on the controller, Udisk file --> Select file. Keep the default values.

13. Set the X, Y, Z axis of the machine as zero, by changing the values in the controller.

14. Click Run/Pause on the controller, Udisk file --> Select file. Keep the default values.

15. Run CNC Router with +Z value ( in air ) for testing and to get an understanding about the cutting area.. If it is found to be succesful, run again with the actual values.

Final Result :

Thank You!
