Heidenhain TNC 640 tool radius offset

Hey ppl,

 

Im having a problem with the radius offset using the Heidenhain post from the Fusion post library. Im using a basic 2D ADAPTIVE strategy to empty a pocket using a single 10mm milling tool. The post outputs L command with X and Y coordinates during the end of the path for the spiral movements. The pocket came out a little small and I wanted to make it a little larger and whatever I did using DR or tool offset in the tool tables did not have any effect on the path. Now, I believe this is happening because fusion is using a centerline path but, is there any other way to do this or what am I doing wrong? Thanks.

Hi

 

Yes for all roughing toolpaths/passes fusion doesn't output Cutter compensation so the toolpath will be all in R0

 

2D Adaptive is a Roughing toolpath and shouldn't be used to finish anything.

 

You should follow up with a 2D contour pass to finish(you can also use 2D Pocket with Finishing passes turned on)

Set the Compensation type to In control:

Now the Finish passes will be output with RL(Climb milling) and the DR will have an effect on the size
