Hi
needsome help. Im runing Hartford matrix VMC-560. I got this problem:
i would like to write a gcode, to make 3 identical electrodes. When i generate my gcode in solidacm, it is in position g45(default). How to change code, so that when electrode on g54 is complete the machine contntinues milling same electrode on g55 and g56 position.
This ismy code :

This ismy code :

You may not even need to use a different offset, where ever you want it to start the next part you can just do a G0 Y0.X100 or what ever the spacing is, if you want to use G55 and G56 then you have to set that in the machine offset page where you want each offset to start, just like when you setup for your G54, work X0Y0 then you do the same for any other offset you want to use

Just saying...That is not ALL he has to do. He then has to re-write the code too.

And is that not what would normally happen, I just gave him different choices 3 ways he could do it in fact, with 2 examples, ( What don't you get ) here is a photo of 400 parts that where machined by just using ( 1 ) offset, 24 parts at a time 2 different vices, all with X Y moves

400 parts, one offset and the code for each part has to be DIFFERENT. What you said is all he has to do is add a move in-between parts. I don't get what you don't understand. Saying all he has to do is add one line between parts is not all he has to do for your method with one offset. He has to change every line of code to make it work that way. Each coordinate has to be changed to reflect the fixture offset for each part.

The OP wants to use the EXACT same code for each part. To do that he only has two options.

1. Write the code for the part to use G91 incremental moves, then move to the start location for the next part and then he can run the IDENTICAL G91 part code from there.

2. Use the G54-G59 offsets. Which entails
G54
{Commands to make part} <<<<
G55
{Commands to make part} <<<<
G56
{Commands to make part} <<<< These codes with the arrows can all be identical. Identical as in they match exactly coordinate for coordinate.
...

His original code was written for G90, so 1 is out unless he re-writes the code to start with. that leaves using G54-G59 offsets. For that he will have to set zero for each work offset (G54-G59) on the machine, but the code for each part is exactly the same, character for character.

Nobody that know how to program uses a G91, with what you say he should do is very inefficient, that is why I showed different choices he could do, so this is what you would have, if you used 3 different offsets using the same program, using a different offset is very Inefficient way to do a job like this

How exactly would that single line of code move the whole prog to a new origin?

I would have modeled it with 3 and prog it like one part. "Nesting"

Like mentioned, you need to pick up the origin for the G55 and G56 just like you do for G54. Then just replace the G54 with the G56

[mactec54]

How exactly would that single line of code move the whole prog to a new origin?

He obviously has repeated his same program 3 times but it did not move to another location because he had not set it

The simple line of code works like this instead of having a G55 or a G56 after the first part had cut after Z retract you just use a X Y move to the next position, very simple, and then run the same program again

[rcs60]

i would write it as a subroutine
this is from a haas control similar to fanuc(may have to be writen as a seperate program then called up )(O1011 instead of N1011)

If he has 3 prog with 3 work off sets they would be identical prog except the g54. So every one would say x1.0 from the origin. So simply moving over would not change the origin for any of them.

So it runs a prog, you tell it to move over x1.0, run the next prog, it will return right to the orig orig and run the orig prog.

Every number in the other codes would also have to reflect that change because they all work off their own origins.

Not at all it would not have the G54 offset in the next program the X Y move take care of that, I do this all the time, it works works well, and is very simple, here is an example, there are other ways to do this same thing as well

The single line move between parts will only work if the rest of the program is written in G91. He has it written in G90, so a single line move like that won't work without G54-G59 offsets.

To use G54-G59 you need to set zero for each one individually. Then when the next work offset is called it will use the defined zero for that one.

Works perfect no G91 needed in any programing like this

[109jb]

Your program is a total re-write, not a duplicating code for identical parts. Sure that will work, if you have a single fixture that holds the multiple parts, but not so easy if you have separate fixtures, or are using separate vises. Your way would require re-writing the code every time, or careful alignment of the individual fixtures/vises if you wanted to set a job up again. G54-G59 won't care if the individual fixtures aren't perfectly aligned and have perfect offsets since each one has its own zero location.

The guy wanted to know how to use G54-G59 work offsets. The answer to that is not to rewrite the whole program to not use G54-G59. The answer is to tell him how G54-G59 are supposed to work.

They are 3 identical parts
I gave him 2 Choices how to setup his offsets G55 G56 Etc , and how to do it with X Y moves, if you have ever made EDM electrodes, which is what he was doing, then all you need is X Y moves to the next start point, depending on his software as to which way is the easiest for him to do it

It doesn't matter if he is making EDM electrodes, or machined dog dooty, he still needs more than a single move to the next start point. Once the machine move to the next start point, the code coordinates will have to be modified by the offset of the fixture. Look at what is in bold above. That is NOT all that he needs to do.

[gapy88]

is it possible to paste 2 another identical program at the end of first one, but just with diferent position (g55) ?

[chuckorlando]

gaby88 you have 3 totaly different prog for the 3 parts and the second one is a macro. Which is fine.

In this case though if you took just the first part and the code for it, the only change per part would the G54 to a G55 and G55 to a G56

In HSM works for multiple origins you put the number in the "multiple work off sets" box on the set up page. g54=1 g55=2 g56=3

[chuckorlando]

" where ever you want it to start the next part you can just do a G0 Y0.X100 or what ever the spacing is"

No you can not.
