What is a .CNC file?
The file extension .CNC refers to a CNC Machine Tool Path file. This type of file is specifically used in the manufacturing industry to direct the operations of a CNC (Computer Numerical Control) milling machine. A CNC file contains detailed instructions that guide the machine on how to cut and shape a 3D part from various materials.
These files are typically created using a software program called QuickCAM Pro. This program is designed to help users generate the necessary cutter paths for machining 3D parts. Essentially, it converts digital 3D models or 2D images into a set of instructions that the CNC milling machine can understand and follow.
However, it's important to note that .CNC files cannot be directly used on CNC machines right after creation. This is because the format of these files is not compatible with the controllers of most CNC machines. To make these files usable, they need to be processed through another software called a Post Processor. The Post Processor software, specifically the Dpost.exe program included with PartMaster, converts the .CNC files into Tool Path Data (TPD) files. These TPD files are then in a format that CNC machines can recognize and execute.
For creating .CNC files, another program called PartMaster CAM (Dcam.exe) is also used. This program is part of the PartMaster application suite, which provides various tools for CNC machining.
To open and work with .CNC files, you would typically use the Denford QuickCAM Pro software. This is the primary program designed for creating and editing these files. If you need to convert the .CNC files into a machine-readable format, you would use the Post Processor (Dpost.exe) provided with PartMaster.
In summary, .CNC files are crucial in the CNC machining process, serving as a bridge between digital design and physical manufacturing. They require specific software for creation and conversion to ensure they are usable on CNC machines.
