Examples

 

To begin we will use the "MILL_XNURBS_CUT-ZIGZAG_XZ" Cycle.  Proper operation of the Expert NURBS Cutter requires the establishment of a relationship between the surfaces to be cut, and the top of the stock material.  The surfaces in the example parts MCADTPC.DWG and MCADFLOW.DWG, have been positioned as though the top of the stock material is located at Z 0.0.  All surfaces are positioned below Z 0.0.

This is an important step as unreliable or confusing results can occur with geometry above Z0.0 in the cad drawing.

 

A ".GEO" file is produced by the system the first time you "Cut" the surfaces contained in the example drawings.  When following along in the examples, always respond YES to the "Define Surfaces" prompt, because there are times when the original ".GEO" file is inappropriate for the exercise in the example.

 

Each Example will include screen captures of the Knowledge Editor, containing the proper entries to produce the results shown in the example.  The only time you will be required to use the Edit Cycle function is in the Vertical Cutting Fallover Example #5.  Fallover Mode is managed by the system for non finishing operations.  The default Fallover Mode is Mode 3.  Fallover Mode settings do not normally change on a day to day basis.  Therefore, Fallover is not in the Knowledge Editor GUI to keep the operation of the system as simple as possible.

 

Detailed information on each of the Cycle Parameters is found in the previous section under NURBS CYCLE PARAMETERS.

 

The purpose of the Examples is to illustrate a variety of toolpath results, by varying the Knowledge Editor, or Cycle Parameter entries.  Feed and Speed Settings do not effect the graphic results of toolpath.
