Fall over Mode in Vertical Cutting


Fallover is a term used to describe how the tool path reacts to the edge of the cutting surface.  If the tool goes beyond the surface or solid edge, it will fall over by some amount.  The control of the portion of the tool path behavior is set in the NURBS_XZ and NURBS_YZ cycles by means of a parameter (#28) named Fall Over Mode.


There are 4 possible settings for Fall Over Mode.  You may specify 0, 1, 2, 3 for this parameter, which will change the behavior of the tool path as follows:


Setting Fall Over Mode:

Using the Modify Cycle button on the Knowledge Editor, select Parameter #28:




In the Edit Value box, type in the mode you want to set and then press Enter.  You should see the list update with the number you typed in.



Fall Over Mode 0:

This method will cut down to the Maximum Z Depth set, then move over by a tool diameter in X or Y (depending on cycle) and then move over and return for the next pass.





Fall Over Mode 1 OR Fall Over Mode 2:

Fall Over Modes 1 and 2 are the same and switch between vertical slicing in X or Y.  There is a slight overcut at the edge of the surface, before the tool path steps over and then returns.





Fall Over Mode 3:

This is the default method if none is specified.  The tool path will cut to the edge of the solid or surface and stop, move over and return.  There is no Fall Over actually done.
