NURBS Cycles Supplied

 

The Expert NURBS Cutter Extension can be operated by using one of the Cycles in the Cycle List containing the word "XNURBS". The appropriate Cycle, used in conjunction with entries in the Knowledge Editor GUI, will generally provide an intuitive method for entering machining parameters. All five XNURBS Cycles share the same parameters. The differing default parameter entries cause them to perform differently.

 

The five Cycles supplied are:

 

NURBS CUT-ZIGZAG XZ

Default settings will produce vertical toolpath at a constant step over equal to tool radius in the XZ plane (angle 0).

 

NURBS CUT-ZIGZAG YZ

Default settings will produce vertical toolpath at a constant step over equal to tool radius in the YZ plane (angle 90).

 

NURBS CUT-CCW XY

Default settings will produce horizontal climb milling toolpath at a constant step over equal to tool radius in the XY plane.

 

NURBS CUT-FLOWCUT

Default settings will produce vertical flowcut toolpath at a constant step over equal to tool radius in the XZ plane (angle 0) or YZ plane (angle 90).

 

NURBS CUT-PROJECT

Default settings will produce vertical toolpath that follows the direction of the projection polyline.

 

 

This section of the manual is supported by a series of graphics, showing tool path results in the drawing. Tool paths displayed using NCSurfer will appear similar to these graphics.  Each of the NURBS Cycles are used. A variety of entries in the Knowledge Editor will give different toolpath results.  Drawings MCADTPC.DWG, and MCADFLOW.DWG, will be used to describe the capabilities of the NURBS Cutter.  The toolpath results shown in all examples were created by using a.25 Diameter Ball End Mill.

 

The NURBS Cutter supports machining with Ball, Bull or Flat End Mill Tools, on solids or surfaces. Once you have familiarized yourself with the operation of the NURBS Cutter using the .25 diameter Ball End Mill Tool, you are free to experiment using Bull or Flat End Mill Tools.

 

Drawings used for the examples will be made available via hyperlinks so that you may download the completed drawings if desired.
