Shadowblock Revision 7 (b) testpiece made!

Shadowcat · Mar 9, 2004

Ok, this is how 7b is meant to look:

This is how the testpiece looks (machining was stopped half way through, there was no point carrying on)

I have some problems

The depth of the 1.5mm cutter is too shallow, I need to change the design of the block so that the max depth is 5mm. After the 5mm depth the cutter becomes a 3mm shaft, which just smashes through things... as can be seen.

For some reason which I still do not understand, the machine also cut through one of the side walls!? !

Added to that, the o-ring passage is too small. I'm glad I tried this test piece before comitting to copper

Revision 8 series is on it's way!

I think that might be a problem with the final block ^_^.

Yeah, I'm going to need to slap that machine into shape >/

Apparently it broke down shortly after being told to stop wrecking my beautiful design.

Grampa · Mar 9, 2004

what kind of equipment are you using??

Shadowcat · Mar 9, 2004

It is a fairly simple 3 axis CNC mill with a 15000 RPM motor and a 1.5mm end mill. I don't have any more specifics at the moment.

lol the cut in the side is funny (yet obviously quite annoying for u i bet :/) looks as if its come in from the side and decided to make itself a nice entrance

Shadowcat · Mar 9, 2004

Yeah, it didn't do that in the computer simulation run :/ ******* machine... ! Revision 8 thread is now up btw

I would mill out all the bigger pockets with a larger end mill to save on that one, and machine time. I also think you shoudl go shallower.

You also might need to re-program that drawing. If it randomly goes through the side, that means its not good

If you want, you can send me the drawing and I might be able to program it up for ya if you get me the info I need and preferably a 2d drawing.
just send me a PM

The new revision is a total height of 5mm, I will send you the new files shortly

Thanks for the offer.

We did plan on roughing the block out with a larger end mill, but for some reason the machine would have none of it and refused to pause in-between the job.

Shadow,

Your pics are down

I would really love to see the test piece.

nm, I see your entire site's down

Hope you get back on-line quickly.

blackjackel · Apr 14, 2004

is this a computer thing?

do you program drilling coordinates into a comp and the computer does the rest? or is this manual?

Shadowcat · Apr 14, 2004

Cyrix_2k: The site is playing up big style, my host has somehow wrecked it AGAIN.. And I have had recieved no reply to my emails about the situation yet.. I will let people know when it is back up.

blackjackel: The entire thing is computer controlled, with the software in use at the moment, I feed it an STL model and tell it what size end mill I will be using and it calculates the 'best' path for the cutting head to follow, feed rates and rpm are manually set on the machine I am using, as you can see though... the path it decided upon was pretty crummy.

A new test piece should be done by the end of next week, I will have pics of it asap.

The 7b is looking to be good.

I really love the paw imprint for part of the design looks very cool.

keep up the good work!

Cyrix_2k · Apr 14, 2004

That looks awesome!But you may want to fix the hole in the side

lol. Hope you can resolve the issues with your host.

VAdept · Apr 14, 2004

Hey at least your making progress, doing that sort of precision work just ins't easy. That 'outlet' you have would definately be an issue on the final block, unless you have some crazy concept we don't know about *turns around*....

Shadowcat · Apr 15, 2004

Hm, not sure I can make that screw-up by the machine into a 'feature'... I'm not Microsoft

Ri0 · May 13, 2004

So what became of this design?
