General Mach Discussion / Re: 4th axis setup

« on: April 29, 2012, 12:24:58 PM »

Hello!

It´s not possible to change the standard output from RC.
All i can change in RC PP is adjust the increment rotation in relation to the standard rotation.
The negative output of A i can´t change. I told you this is fixed writen by program.
Also i can´t change the displayed standart direction of Mach.
So it seems i have to live / accept the displayed reverse Toolpath.
The Axis rotate in Match to RC now.

Maybe Greolt have some idea.

BR and Greolt....

it seems  we  talk about the same thing in different ways. 
i try to exlain the way of tool and axis in the last post.
maybe my message is hard to understand, so sorry for my english.

before i was confused about the different rotary direction from RC between standard and increment rotary operations
and also the displayed screen in Mach. before i thought  the mach screen have to displayed in the same direction.

After checking the conventions i have  figured out,  the PP of RC  have wrong values.
(The direction in standard ops. was cw and the increm. ops was ccw.) 

Now the situation is written in last post.
It seems to be ok that the Mach screen shows revers (tool way) like the description of kneemill.
It look strange, but it seems to be ok.

if someone have another opinion, please tell.!!

i have to tell thank you for your help.

Best regards
Rudi

Yes Greolt!!!

Thats what i want tell. I try in this time to make a picture that shows the situation now.

Greo.   I was take your rules some days ago and try to recalculate the right way of dir,..... with the following solution.

Its the same code from RC to Mach Screen to Workpiece.

so. in the result that mach shows!!! the reverse Dir, but rotate the workpiece right.

( Or it will show ,,only,,  the toolpath and there are maybe normal to show reverse )

I will Post the code !  I hope its help.
Just a simple code without any magic things! 

The RC Sim turn cw!! And the Code follows for A axis rotate cw!

BR.  if you load the code in Mach, your screen shows like mine sended screen picture???

If you run the code, in witch dir the toolpath rotade on screen??? cw or ccw??

Yes!

I know that the axis  do what the code says and it is similar to the convention. I wrote you with pics in Mail.
But if i change the the Port and pin config, only the axis dir change, not the displayed toolpath!!! The axis rotation is correct with RC Code, the RC Sim and the conventions!!

now. all the ,,Problem,, is the reverse toolpath shown in Mach. the axis rotary it´s ok.

Ger.  I changed and play with all the values (port and pins) in config !!!! I will get not any other constellation,

BR. try to put the code to mach and play with Port and pins, so you will see that only the turn dir change, not the path dir on Mach!

For the next example, if Mach accept all written code, it will be the same if have negative or positive values. the Toolpath have to follow in same dir.
RC give out everytime negative A Values in Standard Mill Operations (not indexing) and rotade cw!!! That is fixed in RC and is right to the conventions!!! I can´t change, cause i t is programmed and normal in RC !!!! Also i can´t edit the whole Code, cause by example my turbo wheel have more than 2000 lines with A values!!
 By the way, a lot of People use RC with MAch. 

BR. What do you think about axis way´s and tool way´s???
 I try to explain, if the tool is fixed ( Z) ,....and the axis rotate cw, shows the moving tool ccw on a fixed axis.!!!!! Thats what Mach shows.
could it be the solution?

--- --Yes!!....

I Try to fix it..... , but how??

Thats the reason why i ask  here!!! 

You read the code? i´s very simple code. in  what way in this code can change toolpath on Mach??

The standard turn dir with the  entries from  the neg. values i can´t change. i think that is not the problem, because if i write the same code in MDI i have the same effect.

Do you think about the different Dir from Path and Axis?? Maybe it shows normal.??

Hey!

You got my message?
I´m now sure to 90% that mach ist the problem, cause the PP make just a ,,simple,, code with negative entries on A. But the constellation from the dir and the axis are ok. just the toolpath in mach is reverse. if i jog the axis the dir are also ok. maybe mach displayed wrong or maybe the toolpath ok to !? (i told you).
for example,... if the tool is fixed on z,.... the axis turn cw, but if you fixed the axis and turn the tool it will be displayed ccw.!?!? right or not??

The PP on RC is one from 5 PP for Mach (Mach1 to Mach3, it seems all the same). In RC is an PP- Editor where i can inspect what´s happend and i can change something. The PP File are open and show all important entries for working.
Once i can´t change is the standard dir from 4 Axis Milling  Process (or i can´t find the right key) , the indexing dir i can change.
last  the output code of RC can´t have as much impact of the displayed toolpath.

I  was testing today the things i wrote you, and all works fine ( regardless of the toolpath of mach).
I thought before that i can see always the same path. RC SIM/Mach/Workpiece.
It seems to be a wish.
Thats the last working constellation.

i´ll wait for message

best regards
Rudi

THX for quick answer!!

Yes i try the setup, change entries in port and pins, but the main direction in RC Simulation is cw, not ccw. So the toolpath is different to mach.

what is wrong!?

Best regards.
