I've been using a Hitachi SJ2002 Inverter on my mill for about a year and have had no issues so far...

Tool is making very nice chips now.

Thanks for the kick in the butt!

Thanks for the insight. I will experiment with what I have gathered here.

##### G-Code, CAD, and CAM discussions / Speed Feed and Depth per pass question
« on: June 10, 2008, 10:17:54 AM »
Hello,

I have a Bostomatic 312 Milling Center I Converted to Mach and Rutex. Pretty stout machine.  I'm having a problem calculating the proper speed feed and depth of cut.  I've been staring at formula after formula but I think I am missing something along the way.  Here's my question:

I want to pocket mill some 304 stainless .1875 thick with a 3 flute .375 carbide end mill, coolant on.

Textbook calculations look like this:
(numbers are tool manufacturer recommendation)

RPM: 150 x 3.82 / .375 =1528 (SFM x 3.82 / tool diameter)
Feed: 1528 x .001 x 3 = 4.584 (RPM x chip load per tooth x number of flutes)

My question:
Is the .001 x 3 or .003 chip load the same as the depth of cut per pass?

This seems to light of a cut and to slow of a speed to me.

Confused...

Never mind  someone move my post to here and I found the 2.78 update which took care of it.

Thanks (for moving the post),

##### Newfangled Solutions Mach3 Wizards / G code problem (using Newfangled)
« on: May 25, 2008, 01:27:56 PM »
Hello I would like someone to check this out for me if you don't mind?

Running Mach(tried lockdown and newest), Using Newfangled (tried lockdown and newest) cut circle groove.
After entering parameters I select preview and all looks ok.
Select Post Code then verify tool path and the tool path changes?
Here's the code produced and I noted corrections to make it work with out lead-ins.
it seems like it sets up for the cut then does a tool comp for inner cut half way around then goes back to outer cut?

Have a look and let me know what you see.
Thanks,
Robert

##### General Mach Discussion / Update R3.037 Lathe wizard problem
« on: March 05, 2008, 11:03:54 AM »
I loaded R3.037 and now the wizards won't load?  Any suggestions?  I re-loaded the lock down version  R2.63 and everything works fine.

A friend of mine has a plasma cam and we had the same problem on .5" 6061 T6.  They do a beautiful job on steel but turns aluminum into putty while cutting.

##### General Mach Discussion / Problem with 2.56
« on: October 31, 2007, 01:47:44 AM »
Is anyone else having problems with I&J's on 2.56?  I reverted install back to 2.02 and all works fine?  The problem is it will not display tool path.  It will not even display the toolpath for a part I have been milling for some time?  Weird... something about arc beginning and end.  Great package though... (Mach 3, NF, LC).

I will keep an eye out for the next update...

Thanks,
Robert
