Postprocessor help

[Henry]

Hello!

 

Are postprocessor writing instructions only on separate CD which has to order from dealer?If so,then in this case it'll take too long.

Does anyone know what variable will return toolpath calculation tolerance?And what are Surface Finish toolpaths operation codes(Parallel,Contour,Scallop,Leftover)?Point is,we want our VMC to use same tolerance as MC.

 

Greetings to all,

Henry

 

Wanted to add something about 9/11 but my english vocabulary dryed out.

Henry,

 

Since the response is a bit long, I uploaded a Forum_Post_Question.TXT file to the forum FTP site in the "Text_&_post_files_&_misc" folder.

Roger,

 

Great thanks.Still,next combination worked better:

1501. Insert parameter information in the ascii NCI? y

1502. Write operation information to binary file (.ops)? n

I almost coded what needed and will continue up to the end.

 

Regards,

Henry

Roger,

 

Seems that prmcode 10204 is not reflecting correct cut tolerance.Just try to postprocess at least two operations with different cut tolerances and you'll notice that prmcode 10204 in NCI only holds tolerance from first operation.

Please let us know if you have it same way.

Henry, the parameters are in the .NCI for each toolpath. Make sure you're resetting the variable at ptlchg0 to catch it.

gstephens,

 

That was part of the problem.

Note that (starting) in Mill v9 you have the Total Tolerance button with that value next to the button. This is probably the value you REALLY want. Retrieving the CUT Tolerance value from the .OPS parameters (parameter #10204) will fine

as long as yo do NOT have the toolpath filter active. CUT Tolerance = Total Tolerance is THIS case. If the filter is active, getting #10204 will get you the CUT Tolerance, which now is NOT the Total Tolerance value. If the filter is active, you need to add the FILTER Tolerance & CUT tolerance values together to get the value that will now show up for Total Tolerance in the toolpath dialog.

 

Explaining it all here would not be too useful for most. (Mr. gstephens being an exception!)

If someone is really interested is how to do this in a post processor - please post a reply.

I can do up a simple sample PST that shows how to do this.

Roger,

 

Many many great thanks.This is what can called as service.

Now if I Only could tweak it little more to not output

M112 T-0.999 with contour toolpath

or maybe we will disallow it from it.

Henry
