Hello, my name is Brennan and I'm a systems and support specialist here...
at Tormach, and today we're going to talk about probing routines that are...
already set up in PathPilot. Some safety stuff first, anytime you're running a probe in...
the Tormach machine, we'll want to disengage the spindle. In an enclosure situation we...
...remove the spindle key switch so we're going to open the spindle door which will...
eliminate the possibility of the spindle starting. Also we'll want to make sure...
that the probe is active and working. The setting in PathPilot is specific for...
which type of probe and we've selected the digitizing probe and we also must have...
it set to tool 99 to give it the proper offset and for it to allow the machine to...
run through the probing routines. The last thing we'll set up before we get started...
is our speed with the program routines you can run anywhere between one and 60...
inches per minute I happen to like thirty. One thing we won't be covered in this video is...
the setup of the probe if you'd like to check that out you can check out a...
recently released video done by Daniel Rogge, titled Getting Started with Work...
Offsets in PathPilot. And so just to confirm that our probe is set up properly we...
want to check tool ninety-nine, we have our proper offsets, great, so the first thing...
we're going to do is we're gonna go through some work offset set up and we'll talk about...
the differences between the tabs on the screen and what they can help you accomplish.
So when using the X,Y and Z probe page again we're going to double...
check to make sure our feed rate is set to between one and 60 inches per minute
I happen to like thirty. First one being that we can find our front left corner...
of a workpiece. To set this up we'll want to be approximately 10 to 12 millimeters away...
from the front left corner or approximately half inch. For this first...
example we're going to use the Find corner and set work origin of the front left...
portion of your workpiece to do this you're gonna want to bring the probe down ...
approximately 10 to 12 millimeters away from the corner of the part or roughly a half inch.
From there we can go ahead and select find corner and set work origin.
So at this point we'll want to check and see that our zero is properly placed.
We'll raise the Z up so I'm not going to damage the probe and simple G0 X0 Y0 and...
you can see that does bring us right over the corner of the workpiece.
Next we'll go through and talk about some of the other ways to find an edge and what...
are the different icons on the screen. It goes right in order,
X plus, X minus, y plus, Y minus. On the left hand side this will actually set...
the origin to that for your 0 where find X will simply find the side and...
give you the relationship to zero, and it'll actually display right under this...
tab here and all of these operate the same. Lastly we have find Z the same thing...
applies here if you want to use Z and set work origin that'll actually set...
your zero once you're done or if you just want to probe, so on this next example,
finding X and set work origin or just simply find X. A good example of...
this I can slide this over to the other side of the part...
and ask it to find X minus.
At this point you're not setting 0 but you're finding X and relating 0 to
other side so you'll find X minus and it'll display the relationship the zero coordinate.
Where this other button over here on the left hand side will find the edge and...
make that your 0. or like a pointed out before we can use probe X and set...
work origin, at which point now our X0 is directly over the right side of the...
part, so doing example in Y as well so you can see.
In this example we're going to find Y positive.
Now the work origin is set for the Y positive side.
and if we want to check our work again we can come over to the MDI line G0 X0 Y0,
And now we're referenced to the right hand side of the part. One of the last...
functions on this page is to find the Z offset. Again it's very important that...
you have the probe set up in your tool table offset, which again we've we've...
covered in a previous video. So we move this over the workpiece,
and find and set Z.
X Y Z perot page from here we're going to move on to next tab where we can find...
the center of a pocket or the outside of a boss. On the find pockets center page...
we have the ability to find the center of a circular or rectangle pocket and we...
can do simply X or simply Y on its own...
we are going to do both also we can find the center of a rectangular or circular
boss on this page. The first set up we will use this example to find the center...
of a circle. So I've got the probe lowered into the center of the circle...
approximately and will run this routine and see how it works.
And it stops in the center of the circle and to me that looks perfect so the next...
example we'll move on will find the outside of a boss.
I mentioned earlier that I like to run at thirty inches per minute when using a
probing routine.This was going to be a little longer we're going to speed it up...
we're gonna jump to 50.
OK, so we finished the find rectangular boss center, again we want to check our work.
let's raise the Z up and see how it looks. And that looks perfect.
For the next example we're going to find the center of a circular boss have to
point out that typically you would not hold a circle material in a vise like...
this but for this example this will work just fine.
So I'll want to set up on the left hand side of the circular boxx that we want to find the...
center to and from there we can run the program routine.
And of course, we'll want to look to see if it's in the center. Let's raise the Z up to move the probe tip out of the way. Enter an MDI command G0 X0 Y0.
Of course that looks perfect. So that's it...
quick summary of our program routines already set up in path pilot for more
