Mounting 360 and 120 radiators:

The drill of the radiator and frame case are not coincident, so they need to be adjusted.



The 2nd problem is thick of radiator, the case and bars need a cutting and the grill of top panel need grinding for perfectly fiting (and i have missed to take picture of this.. this will be ok for tomorrow:roll:).



Cut and drill the bars.



Now is ok !:thumbup:.9.thumb.jpg.df50cf1bd4e5ecf6af49c0afd46e33de.jpg



But i have had a 3rd problem with this radiators, they are delivery with M3 screws of 30mm but the grills who i have designed are too thick for them and i have not find the good length  for this diameter. So i have drill and taping the thread for M4 screws. A short movie of this :



I have also edit the build list of first post, finally i'm going to make a dual loop due to complexity of her.

The dremel's last hits :

Drawing and cutting the emplacement for dual pump.



Cutting the 5.25 bay for the future cable cover. 



This is for pass the powers cables of the GPU by the bottom.



This one for fit the distro plate.



And cut of this small fixing lug who make problem for mount the 360 radiator.

Milling  the Asus Republic of gamers logo

I'm going to integrate the ROG logo with RGB lighting in front panel. So for this i need machining the logo in polycarbonate 12mm thickness. This material looks like acrylic but he is less hardness than him and more flexible. The machining is also hardest because it heats and melts more easily than the acrylic in contact of the tool, he need more feed rate. So the acrylic would have been better but i don't have it in this  thick.

The movie is also available in English version with subtitle and description.


The process who i have follow :

1/ Design the 3D model - I have used the CAD software Topsolid 7.1503191188_ROGfaceavant.thumb.png.92a2f1b6d528ba7fa3c50ce2e84692fb.png


2/ Making the toolpath and machining - For FAO part the same software have been used, Topsolid 7.

I have proceeded in 4 steps, u can see them and their cuttings conditions in the next screen :2052601670_Sanstitre2.thumb.png.8b804d4bc19378a5e4a051294f67d4a1.png

  1. Roughing of the surface with Ø8 end mill because i need only 2,4mm of final surface thickness. With this large end mill the time of this step is quick. I have keep a reserve of 0,5mm for remove the cuttings marks due to the finishing step with the ball nose. The cuttings conditions: vf= 2000min/min at 24000tr/min, Z feed : 4mm1203721388_Sanstitre.thumb.png.39220ab5ff05a19f3d0a4116838af8cc.png675364096_LOGOROGEbauche.thumb.png.8a3ed64b7bced45717282203bb117808.png
  2. Roughing the rest of material and the logo in different step of 2 mm with a Ø4 mm end mill. The cutting conditions : vf=2000mm/min at 24000tr/min with Z feed of 2 mm.1138446592_LOGOROGEbauche2.thumb.png.135e4f0cf16738606410dd22b181b48e.pngIMG_0458.thumb.jpg.9a1e6a46b11b16c13f327fab7500e526.jpgIMG_0460.thumb.jpg.56f7be9e3ff40abf322a984c23e7d1fe.jpg
  3. Finishing step - For this i have used a 3D parallel finishing toolpath using a 0.3mm(10% of tool radius) step over and a Ø6 mm ball nose end mill. The cuttings conditions : vf=1500mm/min at 28000tr/min. 1483243519_LOGOROGFinition.thumb.png.9d0aaa5fa0edb27f9c58ac4f8d7b73f5.pngIMG_0463_Moment.thumb.jpg.504d440d0720af512d76856bfc0af61f.jpg
  4. Finishing surfacing - For remove the marks that were left by the ball nose that u have seen on the last screen i finish by surfacing the 0.5mm who rest with the Ø4 mm end mill at high speed. Cuttings conditions : vf=3500mm/min at 28000tr/min, Z feed=0.5mm.119012443_LOGOROGFinition2.thumb.png.fff3f8d0776e9aa38d6a499dfdbd7879.png
  5. Before start milling i have make an other step, i work with a milling CNC machine who use vacuum pump for fixing the part by aspiration. This system is very convenient but not with small part because she can move a little bit due to small surface of aspiration.So for fix it, i have used double face tap.

The result : 1.thumb.jpg.387cf655a8ef030f452e26a584579b36.jpg3.thumb.jpg.aa0f3bc9047388f8f175477794aec383.jpg2.thumb.jpg.afbd1fece472484590717e4c0d80fbc4.jpg4.thumb.jpg.1d73a4cecd74febaaca66f4fee8cc650.jpg
