5. Electronics production

▶ Group assignment ✌

  • Characterize the design rules for your in-house PCB production process: document feeds, speeds, plunge rate, depth of cut (traces and outline) and tooling.

I milled some test files by different Settings and different cut tools.

First downloaded the .pngs files .

Then I import the files in MODS, I configured the different options and saved the file.

  • Trace

Using (1/64) Cut tool

X = 0(mm)

Y = 0(mm)

Z = 0(mm)

Zjopg = 12

  • Outline

Using (1/32) Cut tool

X = 0(mm)

Y = 0(mm)

Z = 0(mm)

Zjopg = 12

Then Send the files to the milling machine by following the same steps I explain in the individual assignment, send and cut the trace, and then cut the outline as you see The first experiment was a complete failure, a mistake in the depth of the cutting and the problem not from the MODs it’s coming from the Z axis setup when I move the Z axis I did not loose it and drop the cut tool to touch the board I’m only moving it by Vpane, another mistake is when I choosing the cutting tool it should be 1/64 but I use 1/32.

I try it again and this time I Set the Z axis very well and I use the correct cutting tool for trace I use 1/64 and for outline cut 1/32, the drilling is excellent there is some scratch because I’m using an old board I running out of my PCB board, but there is a problem with outline cutting I think because the board don’t stick to the panel very well

here is another problem I broke the cutting tool and it’s stuck inside the machine, it took a lot of time to get it out and replace it with a new one. after I tried too many tools to get it out,finally it’s out after I’m using the tweezers it is the hero,

the reason of broke is because when I try to move the Z axis by using the arrow from the Vpanel I make the cursor step in continue mode and its go down very fast so the cutting tool broke and stuck
