[Post Builder] DATUM SHIFT

Hi

 

I have a related inquiry about DATUM SHIFT.

 

## Info

1. Version : NX11.0.2

2. Referance Machine : sim08_mill_5ax_tnc_mm

3. Controller : Heidenhain

4. Request : DATUM SHIFT value output

 

Open sample file. NX11\MACH\samples\nc_simulation_samples\sim08_mill_5ax_cam_tnc_mm.prt

 

The upper main mcs is set to the head side, and the local mcs is set to the lower side.

I try post processor.

I tried to change main mcs to the same location as local mcs.

I tried the post processor again.

DATUM SHIFT Code block is not output.

I want the same settings as now. The post processor is currently configured via PostConfigurator.

(ref:MACH\resource\library\machine\installed_machines\sim08_mill_5ax\postprocessor\heidenhaintnc_PostConfigurator\sim08_mill_5ax_tnc)

 

I want to make it through the existing Post Builder.

 

However, Even if main mcs and local mcs are the same, DATUM SHIFT block is always output. (ref:MACH\resource\library\machine\installed_machines\sim08_mill_5ax\postprocessor\heidenhaintnc_PostConfigurator\sim08_mill_5ax_tnc_mm)

 

Where is the setting wrong?

Some explanations.

 

The MCS with Purpose MAIN is only used if there is no machine loaded.

Otherwise the "Machine Zero" Junction is used for Machine reference zero point.

 

You can adjust the output of the Zero Offset in PC as you like.

If you want no Output of Zerro Offset switch it to off.

Thank you

 

However, I do not use post configurator.

I want to set it through Post Builder.

Try using CSYS Rotation on the part work offset. It usually outputs a transformation.

See this link in docs too:

 

https://docs.plm.automation.siemens.com/tdoc/nx/12.0.1/nx_help/#uidSmiley Tonguearent_groups_parent_group_mcs

 

 

 

It outputs this transformation in the "out of the box" Siemens post. 

 

It should work on the Heidenhain posts form the machine sim as well.
