Hi Shi Zhe,
I have followed this thread for a while.
I do like the design very much for the simplicity of motion,
good balance and most importantly RPM potential.
I have been researching...
Try filleting the flat edge first (if your intent allows it).
Only after this try to put the big Fillet on the top edge.
There is also a trick which uses a Fillet on top of an existing...
Hi,
We're prototyping some 2" deep foam inserts (6# Polyethylene Bun Foam).
We have a 7,000 rpm Haas VF2 and have experimented with various cutters
including router bits and Burrs.
The Burrs...
Hi,
We have an Acu-Rite Millpwr Controller (**A 3-axis controller, not just a DRO***).
We have the head itself, no scales or servos.
It has a 1gb San Disk Memory Card to run programs off of,...
I've been designing Pressure and Vacuum-forming molds for 11 years.
PORUS aluminum. But it is extremely expensive - Use only for porus 'Plugs'. Here is the trick:
1. CNC your mold in...
I don't think there is a G96 option for thoser of us with older controllers.
In that case there is usually a separate 'Spindle Board' in the cabinet that
usually has a few pots on it.
Rather...
There are always fundemental problems when arriving at a
combustion chamber shape that is NOT Round or Cyndrical.
Basically there are two problems:
1. Maximum thermal efficiency is had with a...
OK you Drip-Feeders, I know your out there....
Here's the typical configuration for an older VMC:
CAM: GibbsCam 2004+
Controller: Fanuc 6Mb with a 256K BMU
PostProcessor: Post Haste
In my...
I did some consulting work for a Wind Turbine Company last year.
They were developing a 360KW Turbine which although huge,
is considered only a 'Smal~Medium' size Turbine by commercial standards.
...
As far as I know, this is normal, but I have only used the FANUC/GN6Mb.
When the 'Edit' is flashing the contoller is ready for you to send the file
from your PC. Eventually the NC file will...
On my Fanuc Black-Cap servos, I remove the rear cap
of the servo and there is an allen screw on the end of
the exposed shaft that can be turned.
Sounds like some wires crossed up.
Make sure the phases are not fighting each other.
Ideally you should find a stepper exactly the same spec
to test the driver board.
I presume the new one is...
I had similar problems with a Fanuc/GN6Mb but it was because
there was too much of a voltage drop during certain operations
such as when the spindle spools up or down, or when taking
heavy cuts or...
I went into mt Fanuc/GN 6Mb Maintanance Manual and found the 'Gain' adjustment
on the Velocity Board for the Z-Axis. It is a Pot labeled 'RV1'.
I turned brought the Z Axis down (slowly) so I...
Hi,
I have a GN 6Mb with Fanuc Black Cap Servos.
I had run a series of programs all morning with no problems.
I shut the machine down for a couple hours while I did some
programming in Gibbs....
I wrote my own GibbsCam 'Post Haste' template for the big Acroloc series 100 machines with Fanuc 6M controllers by trial & error over the past year.
The Acroloc 100 requires special handling of...
Thanks Dan,
That did the trick.
I misses 303 in the book when reviewing parameter purposes.
it was all zeros (for pulse encoders) but needed to have the 1 bit at the end
for resolvers.
...
Thanks for the responses.
This machine has several power supplies, including at least 2 different
5vdc sources.
The results of the voltage check revealed some minor variences
(4.9vdc, 23.9vdc,...
Machine: Fanuc 6Mb w/ black cap fanuc servos.
I was running parts all day recently. No incidents but then I did a power-down to reset the machine position zeros and power back up.
But now upon...
SolidWorks is GREAT for small manufacturers.
It still has the best user interface in the industry.
It has 3D export to DWG, DXF, SAT, ACIS, IGES, Parasolid, Step, etc. built-in.
You can also...
If the Converter motor is turning slow it sounds like the windings
are fighting each other, such as one set of windings might be shorted
to ground or such.
Does your local lighting dim and stay...
I have a VMC that puts a fog of 10wt spindle oil through the spindle bearings,
then out the bottom of the spindle. So fine it looks like smoke.
- So fine its hard to imagine any sticking to the...
It is not clear to me if the codes in question are actually copyrighted.
Probably so if they appeared in publications displaying the copyright notice.
As long as GE properly supports any older...
Hi all,
I've been playing with both GibbsCam & MasterCam in conjunction with an
Acroloc series 100 (aka M15) w/ a GN6mb and am trying to modify the posts for it.

I know squat about Mistu alarm codes, but moving a machine can
cause problems common to all:
Check the quality of your 3-ph power to the machine.
A difference in voltage or amperage available to...
OK, it seems the Accel/Decell pots on the Sweo Spindle Board were 'disabled'
So adjusting them was ineffective.
But there is also a pot that is labeled 'Current Limit' that can be turned down to...
I was an AutoCad Guru for 13 years. I started with version 2.17b in 1985.
Ran it at first on a dual-floppy lunchbox (no hard drive, 640K memory only)!
(Thats 0.064 megabytes of Ram, for you...
OK, The Spindle servo drive board is an old Sweo 0028-033
The Sweo board does have independent pots for Accel/Decel.
Both pots were cranked to the max.
When I turned them down full soft, the...
