Hybrid Additive Manufacturing Post..

hi..

 

We are currently reviewing Additive Deposition...

 

I want to ask a few questions.

 

deposition on stepover.jpg

1.  How do I apply Deposition On Stepover to Post?

(It seems to change the Condition Command in Linear Move to the post. What should I do?)

2.How do I work on a layer by merge function using two materials?

 

Please have a good answer....Smiley Happy

For question number 1 - Your post needs to look for a MOM variable MOM_DEPOSITION_ON_STEPOVER and be on from there. By default the deposition on stepover should be off.

 

For number 2 - are you talking two different materials in two different features or some kind of gradiant?

 

Decompose your part for the different features, and build each feature seperately, then merge the two operations together, for different materials.

Above is the deposition of the outside ring, which will be one material

Additive operation for other feature of part

Adding a merge operation so that it alternates the two features, layer by layer, as it builds.

 

I hope this helps.

hello jeff...Smiley Happy

 

First of all thank oyou for your reply.....

 

In case of problem 2, Tool Path can be divided....but....

 

There are not many mom commands available in the post process...

 

After dividing the shape into two parts as shown below, it is only mom_owner_name that it is

 

possible to recognize the two shapes separately when the post is generated.

 

Is there a way to recognize by region, such as Tool name / Material Code when two are divided?

Are you using two different tools and different tool numbers? Or using one tool and changing material between between levels? What version of NX are you using?

 

Some things we can do and some we can not do yet, and some depends on what version youa re using.

hello jeff..Smiley Happy

 

I Used NX version 12.0.2.9 / NX 1855 

 

I Need a mom_command that can be represented as tool, Material, etc, for two parts....

Below are the MOM events for multi-axis additive NX1847 version - You may have to use the owner_name to differentiate which operation they belong to.

 

MOM_level_marker   Event to mark level    
  mom_level_distance the level distance 0.39 Real number
  mom_level_normal vector normal of level   Numeric Array(3)
  mom_level_number the number of the level   integer
  mom_owner_name The name of the operation owning the level - used in Merge Group String
         
MOM_path_region_marker_start   Event to denote start of region  
         
MOM_pattern_marker_finish_pass   Event to denote finish pass    
  mom_pattern_marker_pass_number the number of finish pass   integer
  mom_pattern_marker_pass_shape denotes whether the shape is eithe a inner shape or outer shape inner or outer string
  mom_pattern_marker_state denotes whether the marker is at the start or end of the finish pass start or end string
         
MOM_pattern_marker_infill        
  mom_pattern_marker_state denotes whether the marker is at the start or end of infill start or end string
         
MOM_pattern_marker_spring_pass        
  mom_pattern_marker_pass_number the number of finish pass   integer
  mom_pattern_marker_pass_shape denotes whether the shape is eithe a inner shape or outer shape inner or outer string
  mom_pattern_marker_state denotes whether the marker is at the start or end of spring pass start or end string
         
MOM_path_region_marker_end        
  mom_region_time used for cooling time   real number
  mom_delay_time used to pass value to dwell for cooling time real number
