Steep/Shallow in Hybrid 3D HST

[Maclaw]

Hi Everyone,

 

I want to finish a mould with the hybrid 3D HST. I am machining with a 10mm ball mill. The mould is cut thru (has no floor) and in order for the ball cutter to finish the walls comletely I have to go in the Z direction below the actual wall by about 5mm (radius of the ball cutter). I used min and max Z in the "Steep/Shallow" tab (put "maximum depth to about 5mm deeper) and it doesn't work - the toolpath still finishes in Z equally to where the driving solid/surface ends. What am I doing wrong? Can You help?

 

Thanks in advance Guys.

You could extend the driving surfaces vertically, or add surface extensions.  I do this laterally on a regular basis to get the cutter to enter and exit the part better.
