Art,

Is it possible to make a wheel like the attachment with
no teeth?

Richard

[ArtF]

Yes, two choices. You can create a spur gear of that size. Once its in the tree, right click
it and select "Strip Teeth".

  Second choice is to make a cage gear , the holes will then show up in the dxf as well.

Art,

I like the cage gear, how do I keep 30 holes but increase the size to 7.75 inches.

Nicely done Richard.. Congratz...

[Rocket]

Bob,

Thank you...............at 68 years old, I have finally learned the meaning of "learning curve".

Based on my hours (a time and material job on that gear) I would have to price it at about $7200.00.

Any buyers out there........I will negotiate.....

Art,

I have spent many hours trying to fix the problem where
the spindle goes about 2 inches past the center hole in the gear (where drilling takes place)
then instead of staying up, z-axis comes down and cuts (where it should not be cutting)
and wrecks (what would have been a perfect gear) except for that 2 inches where it
went down before it got to center??????

Attached is the .nc that did this.....it was perfect except for that small part...

Help....

HI Richard:

  I see the problem, just not why it occurs..

G1 Z-0.050 F50
G1 X3.930  Y3.910 
G1 X3.928  Y3.910 

change the above to..

  Actually, make is as above, I get the feeling the move to 5,5 came from some other file..

Rocket:

Watch carefully what your editing, and figure out why each time so you get used
to it .. here some explanation of how this one changed..and what each line is doing.

M3 S1750      //turns on your spindle to 1750RPM 
G1 X3.930  Y3.910 F50 //moves to the shaft hole, at whatever height your at, I added feedrate of 50
G1 Z-0.050 F50 //now drop to -.05
G1 X3.930  Y3.910  //now start cutting
G1 X3.928  Y3.910  // etc..

  Get uses to the order of what the lines are doing. Dont copy in the G1 X5... line, it belongs to a gear that
starts at 5,5 in the X/Y.  This one starts at X3.9Y3.9 so youd want to keep the Z up till it gets there, then drop it down
with the G1 Z-0.050 F50, which literally means "Drop Z to -.050 at a feedrate of 50".

Thanks Art,

Do you use G-Wizard G code editor?  If so, do you like it?

Richard

[DanL]

try NC Corrector v4.0 its a free Gcode editor and a back plotter

[ArtF]

Richard:

  To get my Gcode, I use Gearotic itself, or Vectric generally. Or I write it
by hand if its simple. I do recommend any editor you find you like,
as it will help you learn the language. GCode is simple to learn, and those that
know it, know their quality of output is generally much higher for it. It helps
in all kinds of ways. When in Rome, speak Latin...well, ok.. Italian these days


Ciao,
Art

Thanks....

How did you know I was Italian?
