We are getting one of these machines around the middle of next month. This is my first attempt at programing a mill/turn machine. Although I am already feeling more comfortable the more I practice. Does any one have a machine like this? It has the MAPPS 3 control on it. Im looking for some pointers and I was wondering the pros and cons of this unit. We purchased a 15" chuck, it has 12 tool stations and 1100 psi thru the tool coolant. Thanks

We use butress threads regularly at my shop. Valenite makes a butress snap tap threading insert that works good. Unfortunely our engineers figure all the the O.D. thread over wire information out but it shouldn't be to hard to figure out using mastercam.

"I will start with afew questions. Does anyone know if a 1986 Kitamura Mycenter 3b mill with a Fanuc 11M control can be DNC'ed?,

or the Mori Seiki MV-35 mill with a Fanuc 6M B control?"

We have a mori MV-55 at our shop with a fanuc 6M control and we use predator dnc wireless transfer to send to it. We have never had any problems with it.

I did some of the easy mods myself but we have one machine with an indraumat control that needed to be custom built. We had a guy come in to our shop and work hours and hours setting the post up for our application. This is the machine I am mainly concerned about.

Sweet thanks for the heads up

That should be something cimtec can fix, right?

Ok I will contact them after the boss man decides what he wants to do. Thanks for the response

My boss was thinking of updating MC from X2 to X5. Every machine we have has changes to the posts and one machine has a custom post that was built for it. I heard the logic in the posts between X2 and X5 is different in some cases so I was wondering if anyone has some insight or has ran into any problems with this? Will the update utility do a decent job converting the posts to the new format? We have MCX2 mill/lathe level 1. Thanks in advance

Ok Thanks. I'll try that procedure out.

The structure of the program looks like this

G50 S1118 M42

G55 G00 X0.0 Z0.0 T0 M08

G97 S26 T0808 M03<-------rpm is calculated by 140 divided by feedrate

Yes I am. But will it make 2 threads 180 degrees from eachother still?

Your feeds and speeds are calculated based on the length of the groove from front to back. So taking the offset out WILL throw the timing off.

We do grease grooves all the time. We load these sub programs into the machine and have the main program call them up

%

O1000 (GROOVE SUB 1) first groove starting towards front of part

N1000 G32 U0.300 F3.064 <----calculated by length of groove times 2

Yea it looks like the "W" will just offset the tool after the cycle is ran. So if you removed the "W" it will run the same cycle as the previous. Are you doing spiral grease grooves?

So if I was to just remove that W, would that eliminate my multi start offset?

Do you have access to a programing manual for this machine. If you look up the G76 cycle it will break it down for you. What type of machine is it? I have several fanuc manuals right here.

Ok I posted out the program with default settings. The cycle is posting out something I'm not familar with. Can someone identify this code for me? The G0W.0588 move. What is that code? That an incremental move on the z?

Yes "w" is incremental in Z and "U" is incremental in X

Ok thanks for the reply. Our maintenance man set it up and hes stumped. Might be time to send in a professional.

Has anyone had any issues with a fanuc OT control not reading? It was working and then when I tried to send it a .nc file I would get a 085 Which is the error code for "COMMUNICATION ERROR When entering data in the memory by using Reader / Puncher interface, an overrun, parity or framing error was generated. The number of bits of input data or setting of baud rate or specification No". of I/O unit is incorrect.

I changed the .nc file to a standard .txt and still nothing. I am able to send to all of the other 4 fanuc controls that we have out in the shop but not this one. The "baudrate" parameter did not change in the machine. We are using wireless transfer and cnc predator to send the programs. The program format is all correct, it wont even receive a program that has been proven countless times. I dont have any experience with this kind of issue so any suggestions would be greatly appreciated.

Thank you

hi guys.

I am doing some exercises in my college's lab with mastercam X3. There is a problem I met. When I finished setting up several parameters for my toolpath, then press ok, I have to take long time to wait mastercam finish its preview toolpath creation. The tool will go through every path carefully which I set up. If I set 10 levels for Z depth cutting, I have to wait 10minutes and see the tool touch every level. So, you can image that, if I make a mistake like set 100 levels for cutting a stuff, the only thing I　can do is shut down my computer because during the computer working, any menu is locked up.

 

do you have any same experience with that? How can I change it? I saw another guy play with mastercam in his laptop. After he set up toolpath, the computer will creat preview toolpath at a very short time and automatically.

 

I am so confuse about that.

 

I hope someone could help me out. Thanks a lot

If you post this in the industrial forum you will probably get more responses.

Look for the line shown below.

Change the setting to 0 for 1 line canned cycles.

This is from MPLFAN.PST

 

 

old_new_sw : 1 #Switch old (6T), new (0T+) cycle formats, 0=old, 1=new

Thanks Brian that is exactly what i was looking for

I have a Yang lathe at my shop with a fanuc controller. Its just a standard single turret lathe. The thread G76 cycle mastercam is giving me looks like this.

Does it have something to do with this post block?

I am running MCX2.

Thanks for any input

The program# and sequence# options are the settings for when you post your toolpaths into your editor. Sequence will set your block numbers N100, N102...ect. The stock setup will setup your stock. after you get your dimensions for your stock setup and placed properly on your origin you will need to check the display option so your stock is visible. The rest you will just have to play with and go through the tutorial book or videos. When you create your toolpath just back plot it and see if its what you are looking for.

If you go to the in house solutions website and get a tutorial book that would probably be the best bet and the fastest way to get started. Another good website is eapprentice.net I believe you can get a one day free pass to see if you like it. This website has an abundance of useful videos that would probably help you get started aswell.

I dont have X5 but from reading a bunch of other posts on the forum the machine simulation is driven by the MC toolpaths not the G-code output.

My boss just got a software in called NBS it works ok. but im downloading daftsight right now. Thanks

Thats ok, thanks for the help. Thats a pretty cool tool

I just sent you a email. Thanks

No I dont have access to solid works. And I have little to no experience with excel spreadsheet. Thanks for the replies
