NCG CAM - Area Clearance Roughing

October 2018
Company: NC Graphics GmbH
NCG CAM - Area Clearance Roughing

NCG CAM’s automatic roughing of surface data is suitable for all types of 2D or 3D forms, creating an optimised, smooth cutting motion for high speed machining (HSM) while maintaining part accuracy, cutting tool life and machine tool life. All cutters and tool-holders are collision protected to maximise efficiency and stock model visualisation of the machined part is available at every stage of the manufacturing process.

NCG CAM will always attempt to helix into the job when roughing, but will then automatically adapt to a profile ramping condition by ramping down in Z, while following the toolpath if a helix entry is not possible.

In any area below the cutter that is too small to be area cleared, based on indexable tipped milling tooling which can not centre cut or plunge, the passes are discarded automatically. NCG CAM is then able to detect these areas and locally machine them with rest roughing, avoiding almost all "air cutting".

NCG CAM fully gouge protects the cutting tool and the tool-holder, which is very important when you may have a tool-holder and/or tool that is not long enough to reach. Likewise, it also provides gouge protection when machining using 5-axis machine tools ( 3+2 axis ), and machining areas which might be deemed inaccessible with the standard 3-axis approach.

Cutting tools and tool-holders can be specified either from a standard tooling catalogue or users can define their own custom libraries using the holder designer. These can then be stored specific to each machine tool, or material being machined.
