W have a new engineer that seems pretty lost he just got out of college and this is his first job and first time using a cnc. Everyone thinks the cnc is rocket science and nobody will touch it. what I would like to know is can I learn to write the programs myself and where could I get the info or materials to do this? It is a CR ONSRUD 3-axis machine with 2 tables (areas).Idont know what kind of contreoller it has but it runs off of windows 2000 and has a touch-screen computer.He has just been trained in alpha-cam but I know the last eng used cad-cam also.Im sorry I dont know more but if u ask I can find out and if u can give me any info it woukd be appreciated. Hi David,
If the control uses "G" code type programs, and I assume this to be the case if an external CAM package is being used to create programs, then there are a number of CNC tutorial books around that explain programming using Generic "G" code format. The CNC programming Handbook by peter Smid is one of the bibles that many look to, although I've never read it.

When using a CAM package, if the Post, the program that converts the Tool Path Geometry to the CNC language that the machine's control understands, has been accurately configured, then you don't need a great understanding of the CNC language; but it helps tremendously if you do.

So your challenge is to learn the methods of programming from a book based on Generic CNC code, in conjunction with the Specific idiosyncrasies of you particular control, obtained from the manuals you should have with the machine.

CNC programming, or NC as it was backing in the early 70's, seemed like rocket science back then; but not now. You can definitely learn how to manually (No CAM software) program any CNC machine using the programming manuals supplied with the machine. This is the way the majority of programmers have obtained their skills; particularly the older ones. Broken into various Phases, CNC programming is relatively easy. For example, there is:
1. the Tool Change and Spindle Speed Run phase.
2. moving the tool to the cutting area and applying Tool and Work Offset phase.
3. cutting the profile phase
and
4. moving the tool back to the tool change position phase, ready to repeat 1 to 4 until the program is finished.

I once demonstrated how, what was a very complex program; it contained 28 tools and operations, could be made simple. There were 15 people in the group I was training, so I gave 13 of them 2 tools and operations each to create the programs for. The remaining 2 were given the other 2 tools and operations to create programs for together. I first presented the the task in its entirety for each trainee to create a program for. After a short period of observed panic, I suggested the that they each program small segments of the program as "Stand Alone" programs, that will be patched together when completed. To this suggestion there was much relief, with many comments on how easy that will be. My point being, if a program is broken down into small manageable chunks, even the most complex of programs become relatively simple.

Hi Guys,
I have had years of experience in programing Bridgeport, Hiedenhain controlled 2500 VMCs but have just started a new job programing a Milltronics Centurion 7 VMC with Siemans control and am looking for similarities between the two programing languages. I used text programing on the Hiedehain control, is the text programing the same on a Milltronics Centurion 7 with Siemans control?
eg
T/C 1 X+100 Y-100 RO F9999 M03
Z+2 F9999 M
z-10 F500 M
X+100 Y-75 RL F400 M

etc
I need to write a program to impress my new boss but i am struggling to get to grips with the programing.
Any help greatly appreciated.
Great site by the way.:)

Perhaps I should have mentioned this is a brand new machine. HAAS is sending someone out. I spoke with them on the phone and he was puzzled. When the turret rotates it goes POP as it locks down. The 106 code says something about adjusting turret lock switches and drive or something. I have very little faith in HAAS as it takes forever to get any kind of service after the sale. Was hopiin for some help here :)

Need help ya,
I got a 424 alarm, with an led light on the servo amp/driver (HC) "High current". I called Fanuc, they suggested it could be 1 of 3 things....faulty cable, servo motor ohm wrong, or servo amp/driver problem......I had an electrician come in an check these three items (according to fanuc tech help)...To make a long story short, I had to replace the servo motor. I got the new motor installed and the machine ran fine for a week, and now I'm getting the alarm again. (424) once again I had a defferent electrican come in and check the three items. No problem with them. I started to look online for possible other things to check. One tech guy mentioned there could be a problem on the Servo amp/driver. MY QUESTION IS.... Is there a fuse or relay that could be causing this problem? If so how do I check it?

Either that or your shop is haunted. Better call the ghost busters :)

-okuma howa ACT-2sp ,with Fanuc 0T,when we select left hand side crt is blank,
on Master PCB- L1 to L6 no LED are on.
with cnc on checked +5 ok on master card,axis card and I/O card .
manual suggests memory card and master card is defective.
how to confirm which card is defective.
if we have to replace memory card from other similiar machine what all precautions ?
pl help.

Hello

I just joined and I need some help setting up my 4th axis on my VMC.

I bought this machine and the owner neglected to tell me that somebody had removed the battery when the machine was not hooked up to power.
Well needless to say I have a few glitches:mad:. I have the machine making chips again. It came from the MTB with a full 4th axis. I have the 900 series parameter to turn on the axis but I don't have the correct parameters for the servos and such.

the machine is a 1990 kiwa 510 colt Fanuc 0M, also I listed below the drive and the motor for the 4th axis as well as the Z axis motor for comparison.

I have turned on the 900 series parameter and this turns on the additional axis. I have added the following parameters since turning on the additional axis.

P 8400 00000010

P 8401 00011010 I have no info on this parameter I just copied this from another other axis

P 8402 1000 I have no info on this parameter I just copied this from another axis

P 8420 31 for a 0S type motor

P 8421 50 inertia load. My understanding is to start off low and slowly increase number until it becomes unstable then back off a little bit.

P 8422 111 I think this is easily reversed to -111 to change motor direction.

P 8423 10000 I have no info on this parameter I just copied this from another axis

P 8424 10000 I have no info on this parameter I just copied this from another axis

These are the only paramters I have typed into the control for the 4th axis.

when I power the machine up I now get a 340 APC alarm 4 axis need ZRN, and 341 APC alarm 4 axis comunication.

What's the memory limit on the B model? 2MB?

I have available the following CPU boards:

A16B-3200-0170 FS16B
A16B-3200-0190 FS16C (also FS160C? aka A16B-0222-Bxxx)
A16B-3230-0150 FS

Thanks for the info, much appreciated!

This morning our Haas CNC, while someone was calibrating a tool the machine went straight down on the z axis without any buttons being pushed. When he hit the e-stop it kept lowering until it stopped by itself, the e-stop did not work. It did this on 2 other occasions today. Any one have any idea why? Being that is a safety issue I want to get it resolved right away. Thanks in advance.

This is a crown Lathe. I am fairly confident I have all the parameters set correctly because the ES-L6 machine we have, with the same control, works just fine and the parameters are set the same. The alarm I get when I try to read using the PIP funtion is 5236 RS232C Channal in use ERROR 54540001. Any Ideas on how to get this resolved would be greatly appreciated. I would like to get rid of the floppy drive all together and converting to a USB was discussed at one point but I dont know if this is an option. Thanks In advance Bob.

Welcome Jackson!

Welcome aboard Bob. Glad to have you here.

I have an old CNC, TAKISAWA, Fanuc 3T control system. Master Board A20B-0008-0200
It is broken, no working, no picture, only the light on when I turn off
All volts : 5V, 24V,-15V, 15V are normal
A friend gave me 8 chips Eprom of other master board (My CNC use 10 chip HN462532). I plugged 8 chips into the sockets on master board and turn on. CRT have picture but I can not read the letters. I think my Eproms of master board are bad.
I need help from you on the forums. Someone, you have the source data ( Binary file) of these Eproms. Please help me. I would be thankfull.

I am not familiar with your machine but if you give use the model control and describe what problems you are having myself and or others may be able to help.

Could someone tell me what spindle bearings are in a vmc sf64-a5.

How many of you would be interested in an American made and assembled CNC Mill or Lathe.

Horizontal and Vertical Mills.

Both would have a Fanuc and Siemens option for controller. (FS0i or 30/Siemens 828 or 840)
