What is a CNC file?

A CNC file is a path file created by QuickCAM Pro, a program used to create cutter paths for machining 3D parts on a milling machine. It contains path instructions for cutting a 3D part using a CNC milling machine. CNC files can can be created from 3D models or 2D images.

More Information

CNC milling machines are used to remove material from an object using rotary cutters. These machines are controlled by computers to execute pre-programmed machine control commands. The CNC file is created by QuickCAM Pro to contain a path that is loaded into a CNC milling machine to direct its milling.

NOTE: CNC stands for computer numerical control.

What is a CNC file?

CAD file created by Dolphin PartMaster, a CAD/CAM application suite used for designing and manufacturing components; stores toolpath coordinates for a machine tool, such as a drill, for creating a manufactured part; can be visually simulated in the software.

More Information

CNC files cannot be used directly on machine equipment since they are not recognized by specific machine tool controllers. Therefore, CNC files must be postprocessed using the Post Processor (Dpost.exe) program included with PartMaster. Post Processor creates tool path data (TPD) files that can be translated into a format that is usable by the machine tool.

NOTE: CNC files are created by PartMaster CAM (Dcam.exe), one of the programs provided with the PartMaster application suite.
