[Joey]

I`m fairly new to Fanuc Controls and would like to try start off by using the best and easiest way to write programs. Below is a program i`ve written for our
SKT250MS with Fanuc 18iT, I`m pretty sure you pro`s will find all sorts of useless or redundant code within the prog. I`d really appreciate any help to avoid me using the same rubbish bits over and over again.
Our company has Edgecam which i`ll need to learn, but atm i`m just copy/pasting and editing sections of code to build new progs.
If anyone has an Edgecam Post Processor file for the 18i that would help no end.

Many Thanks.
Great Forum !

[TURNING MAD]

THERE ARE MANY WAYS TO PROGRAM DIFFERENT MACHINES USING MANY DIFFERENT STRUCTURE AND FORMAT. I ALSO USE FANUC 18i CONTROLS AND IMPLEMENT A VARIETY OF G-CDE RESOURCES. I USE GIBBS CAM, CUSTOM MACRO, CANNED CYCLES, AND CONVERSATIONAL. FOR THE MOST PART YOUR PROGRAM LOOKS GOOD. THERE IS ALMOST ALWAYS A DIFFERENT WAY TO WRITE CODE. JUST CHOOSE A STYLE THAT WORKS FOR YOU AND MAKE SURE IT IS EASY TO UNDERSTAND BY OTHER GUYS THAT MAY BE RUNNING THAT MACHINE. I CURRENTLY AM RUNNING MILL/TURN MACHINES AND AS YOU KNOW THESES PROGRAMS CAN BE VERY COMPLEX. I AM ALWAYS LEARNING NEW WAYS TO SHORTEN AND SIMPIFY PROGRAMS. I LOOK FOWARD TO YOU AND I SHARING OUR IDEAS FOR OUR PROBLEMS ON THE 18i CONTROL!!

[xavierdemoura]

Joey,

I work whith KIA too !!! Like Turning Mad said, there are a lot off ways to do an program whithout help of CAD/CAM. I use the take over like an sub program. Like you do in the bar loader !!! But, the principal is that you do an program that you will understand in the future, or another people will understand. Whith the days and practice, you will learn more about the control and will use a diferent ways to do the same program. Practice is very important.

Best Regards

Daniel

[Joey]

Thats great. thanks for your replies.
i had a few days training and have had to use the basic examples given to us by the machine seller. Which is why I put some explanations in brackets to help me remember the codes.
I`ve never used macros, maybe it`s time I got off my ass and started understanding how they can help me.

I was wondering about the amount of times I`m calling the G99.
What I found is if I `search for N number` and restart a program
to run a particular tool, occasionally the machine would rapid to position but then wont feed. I`m probably doing it wrong. I put the control into edit mode and type in say N7 and hit the down arrow key to search, then go into memory mode and cycle start. It seems the control doesn`t read and set the machine thru the whole program but just starts with the N7 line. On the Siemens I would enter N7 and hit the `Search Forward with calculation`
Should I be using the O search button on the Fanuc?

[Joey]

Ah also wanted to say that the simulation graphics on the 18i is pretty poor.
The milling we do is not complex, maybe hex`s and flats and holes on pcd but the simulation gives you no help to verify your code on radial moves.

[xavierdemoura]

Joey,

Fanuc is not the same form Siemens. It´s correct the way that you call an tool. When you put to search an N line, don´t forget that call the program 2 or 3 lines before, for example, an safe position. And don´t remenber too that use the work offset (g54 ...).

Best Regards

Daniel

[TURNING MAD]

YES, THE GRAPHIC DISPLAY ON ALL FANUC CONTROLS ARE LACKING ANY DEMINSIONAL DISPLAY, ONLY SHOWING TOOLPATH. BUT WITH IMPLEMENTING MANUAL GUIDEi, YOU WILL HAVE MUCH MORE POWER TO SEE 3 DIEMSIONAL PART RENDERING EITHER AS A SOLID OR WIRE FRAME. YOU CAN DRAW REALISTC TOOLS AND EVEN DRAW YOUR BLANK SHAPE AS A TRUE PART. DO NOT CONFUSE THE OUTDATED MANUAL GUIDE WITH THE LATEST SOFTWARE- MANUAL GUIDE i-. THERE ARE GREAT DIFFERENCES BETWEEN THE TWO WITH THE LATTER BEING MUCH MORE POWERFUL!! I THINK THE SIMULATOR IN YOUR CASE IS A WASTE OF TIME AND MONEY. ASK YOUR FANUC GUY TO INSTALL THE SOFTWARE AND SHOW YOU HOW IT WORKS. THEN MAKE YOUR PURCHASE DECISION.

[Joey]

Finally had a response and it seems they are already making provision for a higher price tag. ( Hope that doesn`t sound to synical. )

Extract from Fanuc email :-

From an installation point of view Manual Guide i is not a single software package and is configured from software modules to suit the type of machine. Your current control configuration will have to be considered for suitability and if any changes may be required.

To assist us we really need to have a copy of the Fanuc control data sheet which should be supplied with the machine. An example of a data sheet is attached and yours may not look exactly the same but should be similar.

I`m still really keen to have a look at it so I`ll ask them to come in.
Tnx for your info TURNING MAD

here are some examples of manual guide i

Hi,

I also run and program a SKT250MS and I love it. We just got it last Febuary. Im still learning all the shortcuts on the 18-I myself.

I will post a program off of mine so you can compare it to yours.

[Joey]

Enjoyed those pics TURNING MAD thanks a bunch. Sure has a lot more functionality than the bog standard 18i. I have arranged for Fanuc to show us the prog next monday 15th.
Over the phone the guy refused be drawn on offering a ball park figure for the cost, saying our machine would need to be looked at for compatibilty, even on the hardware side !
I thought the manual guide i was a desktop pc based program that would cough up the code and enable me to pump that into the control as a finished program ?


theemudracer I appreciate your program for reference and will be having a close look at it, so might be a few questions to follow
:cheers:
