840D Post - No Arc's

I started a new Siemens 840D post for a DMG table/table machine using Post Builder10.0.3.0. I am not getting any arc or helix moves. If I use the post included with the sim08_mill_5ax machine arc's and helix's are ok. The new post created in Post Builder is also missing "Helix Move" under the "Program" tab.

 

Can someone point me in the right direction?

Re: 840D Post - No Arc's

Hello John,

 

The postprocessor is capable of generating arc and helix moves, but it requires you to set the correct high speed machining settings.

If i remember good from the top of my head, it runs by default in such a high speed mode, that is eliminates all arc and helix moves.

The specific Sinumerik Post documentation should explain more about this.

 

I can also advise you to start of wirth one of the Sinumerik Samples that are provided with the Machine Tool Samples. The postprocessors ere enriched even more than the basic Sinumerik templates that only contain the base functionality.

Gerrit,

 

  Thanks, mom_siemens_compressor setting was the cause. I am building some logic into the post to set all of the sinumerik UDE values automatically.
