Postprocessor - transformed (instanced) operation

Hi everybody,

I've got an issue with post output regarding operation transformations. I found these two topics, which are quite similar, but didn't find an answer.

Actually I'm trying to do the same thing as in first link.

 

When I transform an operation in a circular pattern like this.
15-08-_2017_21-05-18.jpg

I get these values for the first instance (Number 2)

Var: mom_tool_minimum_length = 0.00000000000000000
Var: mom_transformation_matrix[0] = 0.00000000000000117
Var: mom_transformation_matrix[1] = -1.0
Var: mom_transformation_matrix[2] = 0.00000000000000000
Var: mom_transformation_matrix[3] = 1.0
Var: mom_transformation_matrix[4] = 0.00000000000000117
Var: mom_transformation_matrix[5] = 0.00000000000000000
Var: mom_transformation_matrix[6] = 0.00000000000000000
Var: mom_transformation_matrix[7] = 0.00000000000000000
Var: mom_transformation_matrix[8] = 1.0
Var: mom_translation_vector[0] = 99.999999999999943
Var: mom_translation_vector[1] = -0.00000000000005684
Var: mom_translation_vector[2] = 0.00000000000000000

 

The Block is 100 by 100 mm. From the transformation matrix I get the rotation of 90 degrees. But i neither get the center of rotation nor the translation vector makes sense.


Which distance does mom_translation_vector specify?

 

Kind Regards

Alex

Matrix

[0..2] = [i, j, k] values of "x" axis vector of matrix

[3..5] = [i, j, k] values of "y" axis vector of matrix

[6..8] = [i, j, k] values of "z" axis vector of matrix

 

I think there's another variable specifying the origin (looks like it should be about (50,0,0))

It will be rare (I think) that someone has experience with these. I have used them on a 4-axis edm with a rotary (was forced to turn rotary where kinematics don't help.) Also - the recommended structure of the program preferred subroutines/copies. Programmer visualization required verifying (didn't have ISV replay of G code and looping.) I only used a couple of the matrix ones. Siemens would/should be the best resource for giving you this answer. It may be worth a call to help line.

 I am not sure, but transformed operation is just transformation of operation in NX.

It has nothing to do with postprocessing.

 

(Or there is some another variable but I believe not.)

In my case - the operation was instanced about an axis. The postprocessor saw the instanced motion and did not output it - instead calling the original motion after a rotary turn. The only advantage to the programmer of having the instanced operation was watching the motion.
