Hello,

I've been getting some SERIOUS blue chips while face milling 4340 non-hardened steel using a 6" indexable face mill with 10 carbide positive inserts. Is this a bad thing? I certainly know...

Hello all,

I am a mill guy and now making my way to the lathe... more specifically a NL1500 from Mori-Seiki with Fanuc style control.
I would like to hear from lathe guys about the advantages and...

Mr. Beege, and others....

OK so let's assume that we do cutter comp. on the CAM system instead of at the machine... so i program my part letting the software know what cutter diameter I am...

Hello,
I 'm a little bit confused with cutter compensation G41 (for climb milling) g code?

When using cutter comp in any CAM software, I noticed that the G41 and the D value is outputted only on...

Marc c,

If I understand correctly, your operator sets the z zero at the top of the blank unfinished, then proceeds with your first op, then stop the machine with optional stop and reset his Z zero...

Mactec, you are correct about the finished piece not being 3.05 but rather being 3.55". Actually is what I meant.

Thanks guys.

I'd love to hear from other experienced programmers/machinists.

Hi guys,

I'm having a hard time understanding a very basic concept as far as CAM programming is concern in relation to actual cutting... I'm basically wondering where I should put my PROGRAM ZERO...

Mike,
that was funny.... yeah, i think there is hope for us!

HI MIKE,

NEVERMIND I FOUND IT. Sorry.. I was looking in the menues (clearly not paying attention to your direction!!!!!). THX

HI Mike,,
That utility sounds like exactly what I need. Would you mind telling me where i can find that utility in MACH 3. Perhaps i need to download it as a plug in, in which case I was hoping you...

HI guys,
I have been building a homemade mill and it is going well. I have been testing with MACH3 and loving it. I do have a question though:

How do I make sure that my axis travel the...

Hi Jason,
Thanks for the great idea about building a different structure with 4X4 steel tubing. I have a place near downtown where they have a lot of scrap.
Do you think welding the "L" shaped...

HI Jason,

Do you have any recommendations on making my "rig" sturdier. I was thinking of bolting the frame of the machine onto my workbench, so That will probably take care of the flex in the X...

Hey again,
So basically a 4-flute cutter should get twice the feedrate of the 2-flute one at same rpm? Is this right?

Thanks guys,

Jason... tell me you didn't build that machine yourself... I won't believe it if you did. It's amazing! I definately need to stay in touch..... Which state are you in?

My machine...

WOW Jason, that is some fast machining there!!! How are you able to cut like that without lubricant? I thought it was not recomended. What is the final verdict on cutting dry versus lubricant??

If...

HI guys,

I'm a newbie at CNC machining. I have built a 3-axis desktop CNC machine and I have now been using it for about 2 weeks with MACH3 which I love (still the demo version but planning to...

HI guys,
I am currently building a homemade CNC mill from scratch and am learning quiet a bit on all aspects. I have retrofitted 3 axis from unused equipment with step motors controlled by a micro...

Jeff,
Actually I am using KCAM. Somehow i think i cannot control the speed of the spindle with that software but i may be wrong.
thanks again

THANKS GUYS, that is very useful.

As far as for controlling the speed of the spindle, you mentioned using a VFD as per your link. Could I just use a regular dimmer switch like we use in homes for...

Jeff,
Thanks a lot for the quick response.
Are you by any chance the famous/talented motocross racer #801, brother of Mike???? (google him/youself, you will know what i mean)

Anyways, i wonder...

HI THERE,

I am a CNC hobbyist. In fact I am still finishing fabricating my machine as we speak so I am very new at all this. I am using Kcam, although it is been only a few weeks, I find it really...

After reading about this Bobcad nightmare, I would like some recommendations on what software is good for hobbyist as far genarating gcodes. thank you

Thanks guys,
So is it safe to say that 200 steps per inch is precise enough for CNC machining aluminum?? In other words I should just go into Kcam set up and enter 200 instead of the default...

HI guys,
I am building a CNC mill from scratch with parts from other equipment. I have gotten my hands on a great X Y AXIS rig... It came from a wafer handler.. It has rails, bearing trucks,...
