G-Code, CAD, and CAM discussions / Help with a peck drilling cycle

« on: November 27, 2015, 02:51:01 PM »

Hi all

The following code is of a bolt hole circle with a spot drill and the the peck drilling.
The Problem I am encountering is .......on the spot drill cycle all is fine rapid retracting and rapids between points.

On the peck drill cycle the rapids between the holes are not there?  It feeds at normal feed speed.

Is there a problem with the code?

( 10. SPOT DRILL TOOL - 3 DIA. OFF. - 3 LEN. - 3 DIA. - 10.)
(10MM SPOT DRILL CYCLE)

VB and the development of wizards / Re: Help with internal spline Wizard

« on: May 22, 2014, 04:22:06 AM »

Hi BR549

Thanks for trying to help or rather push me to try harder . I guess that is the only way to learn.
I did try a lot of different itterations but the display I get from the toolpathe in mach3 scares me to even try it on the machine.

But I take the challenge, I wont stop untill I get it.
IT works fine as it is at the moment but one fully finished spline at a time.
Maybe I need to change the variables to something that makes more sense to me instead of keeping it from the snippits I got from the other wizards.

Will post again when it works like I want it to.

Thanks

VB and the development of wizards / Help with internal spline Wizard

« on: May 15, 2014, 02:51:48 PM »

Hi Guys

Been doing a internal slotting wizard. A first for me. Not taking all the credit ..... the wizard has been build up from small snipets of code I took from other wizards already posted.
So far its working as planed.
One change I would like to make is to instead off completely  finishing each spline before moving on to the next one I would like to cut all splines by one increment at a time set in the wizard before advancing to the next increment  and loop spline for spline until the final depth has been reached. I think this will give me a more even spline form all round, as the tool might wear.

This is the sub I am using . I really tried to shift the code around to get it to loop like I want, but to no avail .


Code "M98 P0001 Q" & Teeth
Code "G0A0"
Code "Z" & XStart
Code "X" & RapidPlane
Code "M9"
Code "M30"
Code ""
Code ""
Code "O0001"
Nc = 1

Do
     DEPTHPASS = StartPos + (NC*Depthper)
     If DEPTHPASS > (StartPos + Depth) Then
       Depthpass= StartPos + Depth
     End If
     Code "G0 " & Axis  & Depthpass &" F" & feedplunge 
     code "G1Z-" & Abs(Xstart + Feeddistance) & " F" & FeedCut
     Code "G0 " & Axis &  RapidPlane
     Code "Z-" & XStart   
     Nc=Nc+1

If Nc > 3000 Then
       Code "(Out on bad loop, junk program)"
       Exit Do
     End If

Loop While   DEPTHPASS < StartPos + DEPTH
Code "G91A" & deg_move
Code "G90"
Code "M99"

CloseTeachFile

Call LoadTeachFile()
End Sub
Main       
All help appreciated.

Thanks
Deon

General Mach Discussion / Re: Mach 3's ability to display 5 Axis tool paths

« on: May 13, 2011, 04:28:49 AM »

Hi

Yes all Axis are turned on..... At least all axis are physically working under mach3 control.

It is a rock and roll setup. A rotating around the X Axis and B rocking (not a full 360) around the Y Axis.

See the pic for details.

Thanks

General Mach Discussion / Mach 3's ability to display 5 Axis tool paths

« on: May 12, 2011, 06:21:54 PM »

Hi

Like the topic says.....Does Mach3 have the ability to display 5 Axis tool paths?

I have converted a mill(3+2) for porting cyl heads. Tool paths are reasonably complexed .

Tested in verification software the paths show correctly but in Mach it seems like the one rotary axis are missing.

The paths is not like completely messed up but that why the question?

Is this just a display issue in Mach 3?

Thanks

General Mach Discussion / Re: NOISE!!!!!! Please help with shielding technique

« on: March 04, 2008, 03:19:52 PM »

Hi Hood

Thanks for trying to help.
In my quest for a solution I tried something tonight that really confused me.I kept every connection as it were and only physically removed the motor from the setup....eg. no physical contact between the motor and the rest of the machine.

Now I can start, run, stop and do dry runs without any problems .......... but picking the motor up while it is running and then touching the machine metal to metal with the motor all hell breaks loose again.

One thing I did manage to fix was the axis movement when I stopped and started the motor manually without the VFD.I have managed this just by shielding the wire from the switch to the motor.

Still battling for a solution.

Thanks

General Mach Discussion / NOISE!!!!!! Please help with shielding technique

« on: March 03, 2008, 03:27:01 PM »

Hi all

Ive just finished building a lathe from scratch.I firstly build-ed the prototype out of wood to get all the dimensions right.

Been playing with the prototype turning wax for about 6 months without any problems, vfd and all.No special attention was given to shielding cables because I have not experience any noise related problems.

Consisting of the following components:

VFD and motor (3 Phase 380 Volts)
Rutex drives (2000 series)
Cambel breakout board and speed control
Servos
Transformer pack (From 220 Volt supply to lower voltages for the electronics)

Now for the fun part.......................

After converting the wood framework to metal all hell broke loose.

As soon as the VFD starts up every thing go's berserk.
I removed the VFD and 98% off my problem disappeared. The only other noise related problem I am getting is that the Z axis jumps about a 0.5mm when the motor starts up.

I really want to fit the VFD back so I need help in shielding all cables. My electronic knowhow is very limited.

So if some one can explain how to shield the following cables.

Shielding cable to be used has a stainless weaved shield.

1. From the wall ac socket to the transformer pack.

2. From the transformer pack to the Rutex drives.

3. From the wall ac socket to the breakout board.

4. From the Rutex drives to the servos.

5. From the breakout board to the Rutex drives.

6. From the speed control to the VFD.

7. From the forward and reverse relays on the breakout board to the VFD.

8.From the VFD to the spindle motor.

9. From the drives to the encoders.

If some one can explain to me fasten the shields and where not, and do I use the shield as ground or as 0 Volts or none at all.

Pretty Please any help will be appreciated.

Thanks
Deon

Hi Graham

Yes you are right ........but the principle is the same.
Thanks for the input anyway.

Hi Poppabear
 
Just downloaded your ellipse wizard. Will check it out in a minute.......
A Couple of questions for you if you do not mind.(Wizard related)
What is the possibility to do a Turn wizard that can cut unround(By this I mean oval like in a cam shaft of a car)
I do realize that your spindle would have to have a encoder to be in sink with your X Axis.
If not possible to control in Mach3 Lathe then I guess one can use Mach3 mill (4th axis + 1 linear axis)
If you are up for a challenge or to make a few bucks contact me.
I need this for measuring and cutting automotive cam shafts.
 
Thanks
