Re: [Emc-users] Tool Height Sensor Position

[Leonardo Marsaglia]

Hi John,

I myself have to install and try the wireless one I purchased for the
router. (The wireless MPG from the same supplier is working excellent by
the way).

About the placement of the sensor, I vote for the permanent mounting
solution, as long as you know you'll have enough working area for most of
your jobs to avoid removing it frequently.

Re: [Emc-users] Tool Height Sensor Position

[Nicklas SB Karlsson]

Put in on the same place on table then needed. Workshop is not heated
so bring it inside then not used to avoid corrosion.

[Emc-users] Deep slot chip removal

[Nicklas SB Karlsson]

Milling a deep pocket spiral down work great first turn but after a
while torque is not enough and mill stop. Suspect it is because mill
have to cut old chips in addition to machining part.

Maybe it is a good idea to use drill bit a little bit smaller than
slot?

Re: [Emc-users] Deep slot chip removal

[Matthew Herd]

A drill for an entry hole is never a bad idea.  Other options include using
a tool with a smaller diameter or fewer flutes.  Can you improve chip
evacuation?  That's never a bad idea in any event.  If feasible, a vacuum
or some repeated blasts with the air gun are helpful.  Also, can you reduce
the ramp angle for the helix?

Have no really good method to get the chip out of the slot though could
stop and manually remove most of it and drill thru holes. Tried
reducing the ramp angle but did not help or only a little bit.

Smaller mill or first drilling thru holes is ideas I have.

Re: [Emc-users] Deep slot chip removal

[Matthew Herd]

What size mill and tool are we talking about?  Is this <1kW of spindle
power?  Is the tool <10mm?  I'm a bit surprised that the spindle would
stall due to uncut chips.

[Emc-users] Clausing NC Progress

[John Figie]

I took Andy Pugh's suggestion and made my own .comp for the tool turret.
Next I have the Huangyang VFD using the hy_gt_vfd hal component. Yesterday
I installed the spindle encoder and added the hal spindle component for the
3 speed geared head. I have some suggestions for some small changes to the
documentation that might make understanding how to use this comp much
better. I know Andy just took my last corrections to the docs and updated
them. Is that the best process? I think I should do something soon before
it is forgotten.

Here is a video of the second time using the machine now with a working
turret and spindle encoder. I will have to try threading soon.

Clausing NC 1550


Yet to do:
1) Add a braking resistor to the VFD so I can stop faster.
2) Get a proper E-Stop mounted on the machine and some other important
buttons like program pause and run. Maybe on the panel below the speed
selector I will add things like the VFD faceplate, E-stop. Start and Stop
buttons, MPG etc.
3) Figure out how to index the head so I can cut some splines.
Maybe I will mount a disk with holes like an index plate on the back of the
chuck. But what about using the spindle orient g codes and then some kind
of holding brake?

Nice!  

A couple of questions.  As you are facing the spindle speeds up and down.  So I 
take it you are tracking diameter to maintain the same SFM.  But then when you 
start turning the spindle is slowed down.  

So the question I guess is if you start facing at say 1" diameter with 1000 RPM 
would you not also turn at 1000 RPM?
Or am I missing something?

You are correct. When I did the CAM I wasn't consistent with feeds and
speeds for each operation.

Re: [Emc-users] Clausing NC Progress

[John Dammeyer]

Hey John,
Since I was testing an ELS software tutorial I thought I'd grab a scrap of 
something that is very rusty.  I faced it off at 586RPM.
Then turned it at 586RPM.   It's about 0.84" diameter and SFM reported by the 
ELS was 132,
First pass 0.008" per rev and 0.010" depth of cut.
Second pass 0.003" per rev and 0.003" depth of cut.
You can just spot the carbide insert underneath the rust dust.
It's very smooth.  Wouldn't take much to polish it.

[Emc-users] ? cutting a square carbon fiber tube ?

[gene heskett]

Greetings all;

An unusual question. How to cut, neatly, and squarely, a 20mm square 
carbon fiber tube to length, say 550mm out of an 800mm tube. I'm making 
a linear rail bearing X axis for two of my 3d printers,


I have a die grinder that I can mount in a quick change holder, and a 2" 
by 30 thou CBN disk and 1/4" arbor, and a 4 jaw chuck on my Sheldon.


Do I need to print an 18mm square plug to insert into this tubing to 
support the 1mm thick tubing walls, or can a relatively light grip be 
enough to hold it fixed while I turn slow and cut it off with the CBN 
wheel running at about half line voltage in the die grinder?


All I can see in my minds eye is a hugely ragged edge cutting it by hand 
with a hacksaw.


Better ideas anybody?

Thanks All.

Cheers, Gene Heskett.

Couldn't resist.  Some 400 grit, 600 and polishing compound.

Probably the nicest finish I've ever done.  Usually never go that far.  Maybe I 
should.

Re: [Emc-users] ? cutting a square carbon fiber tube ?

[Chris Albertson]

Cutting square tubing is no harder than cutting molding around a door
frame.   Use a miter saw.   A fine tooth hacksaw blade works well for
carbon fiber.

If you don't have a miter saw, print a plastic guide block that holds the
tube and has a slot for your hacksaw.

Finish with a sanding block to make the edge nice.   I've cut a lot of
fiber tubes, sharp saws work well. but glass and other fibers dull tools
really fast.

You can make a really strong part by gluing fiber tube into 3D printed
blocks
