Computer Controlled Machining
I designed some parts that would be cnc'd using the ShopBot. You can see more how I got well rounded in the woodshop in the Computer controlled Machining Week. I learnt a lot from the mistakes I had during that week and avoided them while I was fabricating the structure for my final Project.
I saved the designs I created for my final project as DXF then imported them into the VCarvePro to set the settings for the machining operation.
Before imporitng them into the Vcarve, I used Rhino to separate them into layers since I have multipe jobs.
The tool I used is the 1/4" endmill and set the settings for it as seen below.
The first job I set was the 9mm pocket as seen below for the parts marked in pink.
The settings for the 9mm pocket is seen below.
Next, I set the settings for the 5mm pocket where the acrylic separation would fit.
The settings for the 5mm pocket is seen below.
Next, I set the settings for the 17mm pocket where the servo motor would fit.
The settings for the 17mm pocket is seen below.
Next I set the inside cut as seen below.
The settings for the inside cut is seen below.
Lastly, I set the settings for the out cut as seen below.
I set the depth of cut to 18.5mm not 18 to make sure it cuts all the way through since there's a sacrificial layer any way.
I had 5 jobs to do, 3 pockets, an inside cut and an outside cut. The whole process took an hour and a half as seen below.
I used the preview to make sure all the jobs were ordered correctly before launching the machine.
Then I set the zero of the machine for the x,y and z axis as I learnt before in the CNC Machining Week.
The above video shows a part of the milling process.
Once all the parts were done, I had to do some sanding to get a perfect finish, then I painted it all in black, even the 3D Printed parts. The only thing I left in white is the funnel.
