Fagor 8055MC control. Question about 5 axis.

[Bruce Caulley]

Ahoy!

Machine is a 5 axis gantry router. Currently the pivot distance and tool length are entered in the cam ( UG )side rather than at the control. I haven't been able to find anything in any of the manuals here, or even on the website to tell me wether or not I can enter the pivot distance in the parameter table of the machine or not. Tool lengths could then go in the tool table where they belong and there will be no more need for adding up a lot of numbers everytime the programe is posted.

 

How do I tell if this feature (TCP?) is activated?

TCP?

 

Tool Centre point Control?

[Bruce Caulley]

Yep, TCP. Or I would call it dynamic compensation if it were a table/table machine.

 

At the moment there is a chart of tool lengths taped to the computer along with the pivot distance. In UG the tool length and Z offset (pivot distance) are used by the post to determine the correct 5 axis motion. If the tool is changed you need to run upstairs and make the changes and re-post.

 

The company was started by a couple of blokes with no machining background and they have done an admirable job of getting to where they are. I need to be able to demonstrate and implement more up to date methods for using the machine so I can up the efficiency. Getting the tool length issue sorted is my personal #1 as seeing the amount of time and trouble that is spent on an issue that would be non-existent anywhere else will very shortly get on my xxxx.

Bruce,

 

G48 S1; TCP on

G48 S0; TCP off

 

Punch it in and jog the rotary axis for a quick look on how it works.

 

Your post will need some changes for TCP to work properly.

How does the control know how long of a pivot length you have... We also have a 5 axis router with the xxxxor 8055 control. I have been reluctant to use the TCP funtion because the manual is quite confusing on this issue.

Eric,

 

When we got the machine installed the setup guy told me I wanted TCP so he set up all the parameters and so far I like it. A couple things that come to mind.

 

-your post must post out zero tool length & zero pivot distance.

 

-I touch the tools off table using a program (M100) to set tool lenght of active tool.

 

-pivot distance is stored as a general machine parameter P97

 

Hope this helps explain a little, there is more but would need some time to look over manual.

Is this machine a Quintax??

 

Ours is a 2001 and we do not have the tool touchoff pad.

 

I guess that you realy do not need one if you use a presetter on the table and set it up to do the same thing that the tool touchoff pad does

 

the post that they supplied me does allow me to post zero pivot and zero tool length.

 

what if you use multiple tools in a program ??

[Greg Williams]

Ok, I must be missing something here. My understanding is that Tool centre point control is a completly different kettle of fish to Dynamic offset compensation.

At the control:

You should see TCP in the list

Thanks All!!!

 

Greg,

TCP and Dynamic comp aren't technically the same thing, but they achieve the same result. On a head/head tcp allow you to programme without worrying about the pivot distance. On a table/table dynamic comp allows you to programme without worrying about the rotation point location.

Eric,

At the control,

 

Tables

Tool Offsets

 

is a table of pivot lengths. The values change after doing a toolset off the touch pad or they can be manually changed. HTH

our machine was made before they had the touchoff pad option so I guess I can manualy input the values by calculating what the pivots would be for a given tool.

 

this is the table that the G43 tool length comp. uses correct ??

You need to talk to Greg from Gunther, Texas. He has a 5 axis xxxxor 8055 machine. He is usually lurking around here somewhere.
