Hi all,

I'm not sure this is the right place to write this thread, so I hope an admin will move it, if posted wrong place.

I have read a bit in here from time to time, when I have had some problems. And a lot of times I have found the answer to my queries .

But this time I'm having trouble getting our "turning-table" to change the feed rate, when I need to turn it.
I'm using a YCM106A Vertical milling machine, with a Fanuc MXP-200i steering. And our "turning-table" is a Golden sun CNC-251R.
I can turn the table using this command:

M28;
G54 A180;
M27;

And it then turns with a feed rate of 1000mm/min. I would say that's it rapid speed, not feed.
So how do I get it to turn in feed rate instead?

CheeRS and greetings from Denmark

Try adding a G01 and a feedrate to the move block. Don't forget to program G00 for your next rapid.

M28;
G01 G54 A180. F360. (FEED AT 360 DEG/MIN);
M27;

Tried that, but then it doesn't move at all...

Did you put a decimal point in the F?

I believe our machine is setup so it doesn't have to have the decimal point. So I just wrote:

M28;
G1 G54 A180 F500
M27;

And then nothing happend, it just stayed the same place...

Just to eliminate the possibility, why not try a decimal point in the F?

I assume your machine has the 4th axis interface, and you're not plugged into an external controller box, correct?

I just tried typing F200. and still no go.

However I do notice that it says the distance to go on the screen, In this case it was A180, as I wanted it to rotate the 180 degrees.

By 4th axis interface, do you mean the screen on the machine? If so, yes I have the interface. Sorry if I misunderstand what you mean mate.

And I would say no to the external controller thingy. As our rotary table is connected to the machine directly.

And it not a problem to get it to rotate, I just can't control the speed it rotates with, if you know what I mean. It just rotates with rapid speed, and I want to control it with the feed speed rate.

Again sorry if I get things misunderstood, or mixed up.

Who installed the 4th axis on your machine? It sounds as if the parameters aren't set correctly. It's been my experience that the table manufacturer sends a list of parameters with the table. Do you have that?

Well, we can install and remove it ourself. So when we don't need it, or need more space for vice's etc., we can remove the rotary table.

And when we install it, we turn off the machine. Install it, plug it in, then turns on the machine, and types in M451, and do a reboot. And then the 4th axis is ready to use.

No we didn't receive any parameters with the rotary table.

I figured it out now. It just needed some rev's on the spindle.

But thanks for your help anyway mate, appreciated.
