Make something big

On this week i got chance of making something big. Because there is a customer how bring a job of making office furniture table Which look like this below.

Designing

For design i try to use SolidWorks for design that table first i begin on top views of the table and leg of our table.

After design all parts of my object i try to assembl it.




Top view 1





Top view 2





Top view 3





This is the leg of our table



On this images below i try to show the way you can pass when we want to paint your object in SolidWorks. I paint it because of Clients He buy MDF material which is mahogan. Actually look like this. i was paint.

vcalve shopbot editor

VCarve Pro V9.0 ShopBot Edition provides a powerful but intuitive software solution for cutting parts on a ShopBot CNC Router. There are tools for 2D design and calculation of 2D and 2.5D toolpaths and along with the ability to import and toolpath a single 3D model (STL, OBJ etc.). There is also support to import multiple Vectric Clip Art 3D models (V3M) to create 3D assemblies.

The software can import 2D designs from other programs but also provides a full set of drawing and editing tools.



after joining all part DXF file.

After putting DXF file on Vcarve editor i supposed to put doggy bones on my design in order to assembl in easy way. But i didn't put doggy bones because of i putting a tolerance of 2 mm in order to make assembl in easy way.



Pocket



Editting tabs in order to avoid bouncing of material.



After calcaluting all profile and pocket



Direction of Tool

shopbot Machining

Shopbot is CNC Routers for fabricating with wood, plastic, aluminum & more.

the things you need to known before you start use shopbot is this you must care yourself.other thing it is better to take like ten minute of running it on lower speed like (9.000 rpm) than it use when it cut.before starting using in order to make it hot




Make sure if control box is turned ON.





This is the list toolpath include both pocket and profile.






This the location of all axis include X-axis, Y-axis and Z-axis.






This is switch of control box and display of speed.






Putting and adjusting material on the bed of ShopBot.






On fixing material make sure MDF material it touch on shopbot's bed very well.







Emergency button include start, reset and stop button






Because our shopbot it doesn't take Z-axis automatical(with plate) Now we have a trick of taking Z-axis manual. That trick is to put tool into the material we going to cut as you seen on the following picture.






After adjusting all thing needed i cut all parts.as you seen on the following picture.

Assembling

After cuting we assembl all part of the tables.But it not easy to do it.But again we try.

final work
