fanuc 31i-c

[dcutler35]

does anyone have a post for a 4 axis hbm cnc with thru the spindle coolant also what is the baud rate and other I am using master cam but I also have accces to gibbs cam any help would be grately appreciated

You do not have the generic Fanuc post for this? GENERIC FANUC 4X MILL.PST

Should go with MILL 4 - AXIS HMC.MMD

oh ok I saw it I guess now all I have to do is figure out how to load the programs into a fanuc 31-c controller I tried using a flash card but it would not read it today I am going to use a laptop and a chord using bobcad 23 editor to send it. I was amazed on how different the 31i-c controller was compared to the 18 i That i am use to

tryed changing the IO channel in the settings in offset?

mine is 4 for flash card.

Also how big a flash card are you using. do not us any bigger then a 1gb or it will not see it. What is the HMC is it a Matsurra or a Mori Sekei

[underthetire]

A mori would have USB that new, as well as network standard. I've used larger than 1gb without issue on the new controls.

the machine is hunnming from china the builders left yesterday and they spoke chinese they did not have it quite right till about quitting time they loaded the program from my 256mb card but they had the control language in chinese so I could not follow the steps I have used a vmc for a while but one thing that thru me off was the spindle is in z and the column is in w and that leads me to another question how can you set your tools length in z when you also are moving in w

[txcncman]

Tool length Z would always need to be set with column W at the same position, assuming the "home" zero position.

[dcutler35]

So when you move in w then you have to touch off all your tools ? I know you are right I just am having a hard tjme figuring out how to start setting tools and running jobs without constantly remeasuring. So every time you change w you must measure your tool and unless there is also a way to set an offset in w? I am a little lost is there a more logical approach to this ?

[txcncman]

The way I have done this in the past, set W at any level. Touch off all tools needed for job and set tool lengths. If same tools are used, and W changes, this will be accounted for in work zero setting (i.e. G54).

Maybe if you watch this video it will help. Video: CNC Training Video Setting Tool Height Offsets (Lengths and Diameters) for a Knee Mill

i think i am starting to get it but when mesuring the tool from home I normally put that value in that tools h offset. It seems that what i need to do is find out that tools lenght using a reference tool ie mesure the ref tool and subtract tool length from that to find the exact tool lenght after that is accomplished to all tools i then can move my w to any position then touch off with any tool in my library and set my z axis in g54 ? that is where i get a little confused

Ok. As indicated in another thread (http://www.cnczone.com/forums/haas_m..._question.html), maybe you need to move away from just pushing buttons in a certain order to really understand what the numbers mean and how the machine control uses those numbers. Start with putting zeros in all offset registers and move all machine axis to Home positions. Then program:

T01 M06
G00 G90 G54 X0. Y0. W0.
G00 G43 H01 Z0.

Then press cycle start. See where the machine moves to. Note the numbers for Machine Position and Absolute position.

Now touch tool 1 to the table and put in the value for the tool length offset. Move all machine axis back to Home positions. Then program:

T01 M06
G00 G90 G54 X0. Y0. W0.
G00 G43 H01 Z2.

Then press cycle start. See where the machine moves to. Note the numbers for Machine Position and Absolute position.

Now put a piece of material on the table and put in numbers for G54 Work Offsets for X, Y, and Z and repeat previous steps.

Now put in a number for W and see how that changes things.
