Nesting and Soft ONE-CNC for Generation of NC Code

You can use a nest the parts manually or third party nesting program. A skilled CAD people can nest the parts efficiently using AutoCAD alone. This manual procedure is often economical if the parts are many different parts and complex of greatly different complexity have to be nested, as it is often the case for shipbuilding.

Open a new drawing for the nest. Place one or more rectangles on the reference that indicates the size of your stock plates. Insert the all blocked parts randomly on the drawing. Nest the parts starting with the larges ones using the move and rotate commends until all parts are nested. You may want to place some parts in through holes, such as small brackets. All entities with outside cuts within a through hole have to be changed to the INSET layer. They cannot contain any inside cuts!

The resulting drawing contains all the required information to produce the NC-Code for a number of parts to be cut from one plate. Before exporting the drawing to a DXF file explode all blocks and plotlines. It is advisable to freeze or turn off all layers that are not required for NC processing. You can save disk space and time by writing just the entities to the file. When prompted by AutoCAD  for  'Number  of  decimal  places/(Entities)'  enter  'E'  ('O'  for  objects  in AutoCAD 13) and select the entities by dragging a rectangle.

Start execution of Soft ONE-CNC for generation of NC code with the following steps:
  •  Generation Æ   Complete path /Marking path/Cutting path for generation and optimization of all paths/marking paths/cutting paths.
  • File Æ Save NC code - for saving CNC code according to preference settings from “Tools” menu
  • View Æ Simulation for checking the tool path.
