Need help!!!

[Thirteenth]

the first code i posted was mpfan. then we realized we had to change that. so we did...

 

we have done the home and the location of the material thing.

 

my question, does it matter where the part is drawn in mastercam in relation to 0,0,0.

Yes,and No... You can manipulte your 0,0,0 with WCS. Your machine still has to know where your part is. If you draw your part 20" away and the machine has 15" travel than you will get an axis overtravel.

that is the code that works, well loads.

[robk]

After I deleted line N292 in Cimco editor, your X,Y ranges are as follows...

 

 

Your part is somwhere in space... You need to give it 0,0 somewhere.

[chris m]

OK, now I'm confused. I did a side-by-side comparison of your 'non-working' file and your new 'working' file and the code is identical except for the program number and one tenth on an arc move:

 

G3 X5.579 Y7.7931 R.7795

 

vs.

 

G3 X5.5791 Y7.7931 R.7795

 

Did you change filtering or something to create this difference?

 

Strange...

I always orient my drawing in regards to 0,0,0.

 

It is easier for me to do it that way so when I set my machines up you dont have to do alot of figuring or inserting machine offsets in the control.

 

I did have a small problem where sometimes my control would fault out if 0,0,0 was in the same place as the center of an arc in the cutterpath.

 

So whenever I got this fault, I just set the origin .0001 off in the x and y.

Did you discover how to see and set the G54 value in your machine yet?

[crazy^millman]

I wonder if the Machine even uses a G54?

I agree. Since all of his X and Y numbers are positive AND relatively large for what I assume is a small machine AND the first working program had no work offset call.

 

As far as Work Offset zeros I like to work off the back left in a vise and the center of round parts whenever I can though I'll set it up differently sometimes if the dims on the print all come off of some other location so the operator sees numbers on the screen that make some sense when compared to the drawing.

[crazy^millman]

Another little thing I like to uue for Parts is the Bounding box. I will usually create this on a seperate layer so I can turn it off and on when I need it. I use this for facing and other things like using the point in the center for a WCS or to translate a part to the origin.

 

Just in case you wonder where it is. Create/Next Menu/Bounding Box.

Does your machine look like this?

 

 

This is what we have at the local community college.

yep, only....more closed off and what not. and its a EMCO 50-PC mill. what the difference is, i dont know.

[CNCGUY]

I saw a PC-50 last week at EMCO in Columbus OH.

 

Was designed for schools.

 

Cute little machine that runs with a PC and is capable of using Fanuc or Siemens control, boot PC with desired control.

 

Thats all I know about that!!!

[Philcott]

Thad,

 

I see the college teaches real world machining practices. Disable door interlock, run with chip guard open and place a hand as close to the cutter as possible (to reduce chatter). I can't tell, but, I would guess the operator has his saftey glasses properly placed on the top of his head and not on the bridge of his nose. J/K

 

Phil

[jbel]

PhilCott,

 

Also notice highly rigid pony clamp setup holding workpiece. When two pony clamps won't do it, just use four. Then if that wont do it, just hold it with your hand like you should have done in the first place!!

[chris m]

From the look of the thing, Phil, you could probably stall the spindle if it hit your hand.

 

C

 

P.S. I like the clamps, too; I wouldn't hold up a blueprint with those...

[jbel]

Also notice : watch/wrist severing mechanism is in ideal position to remove an extremity should something go wrong.

 

Thad, please tell us that the operator wasn't removing chips from the EM with a rag while the spindle was on!!

[P_Scott]

Thirteenth,

 

From the looks of the code you supplied us earlier and the photo that Thad supplied I would say the easiest thing for you to do is Xform-Translate your geometry from the location it is on your screen, to Mastercam's Origin. You can then regenerate the toolpaths and re-post it and you should see the coordinate values in the appropriate range of motion (work envelope) for that machine. Let us know how you do.

 

Don't let these guys fool you. Kidding aside, those who contribute here are among the best in the business. Welcome aboard. HTH

[Thirteenth]

well i re-drew the stuff, but now i cant get it to load again, arg. ill have my teach try and do what ever he did to get the last one loaded.

I dont understand why Everyone doesn't already do it this way in the first place.....Cause it seems like the logical way.

 

I mean not transform it exactly, just use Mastercam's origin

Luckily, I never had to run that machine. I went to a school that had a Haas machining center and turning center.

 

These are the CNC machines that thy have here where I just finished up my MC class. Here is their lathe.

 

 

 

Our computer lab was inside the machine shop. I took my camera in one night to get some pics. I had a classmate put his hand in the picture to give you an idea of how big these machines were.

ok new "alarm message". god this is getting old.

 

"2520 ORD 1 RS485 device absent"

"2520 ORD 2 RS485 device absent(AC)"

 

right....anyone?

[dan m]

Thad,

Looks like schoolcraft to me.

[Thad]

You got it Dan!

[dan m]

I did know they had a mc course. was it worth takeing?
