What is CNC?
CNC – Computer Numerical Control – Taking digitized data, a computer and CAMprogram is used to control, automate, and monitor the movements of a machine. ... The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions.
What type of file do CNC machines uses?
Every CNC setup is different, but there are general file formats that most machines support. The commonly accepted CAD formats for CNC machines: AI, PDF, DXF, DWG (for 2D files) STL, OBJ, DXF, STEP, IGES, DWG, 3DM (for 3D files)
Steps to Create a CNC Drawing
Creating a CNC program is a three phase process:
1.The part is drawn in a CAD(Computer Aided Design) drawing program such as AutoCAD.
2.Then a CAM (Computer Aided Manufacturing) program is used to convert the CAD drawing to G-Code.
3. Lastly, the G-code controls the CNC mill as it makes the part.
Possible CAD and CAM Programs
Here are short and very incomplete lists of CAD and CAM programs. Prices range from free (A9CAD) to several thousands of dollars. Don’t take these lists as recommendations. These are just the programs we found in a short session with Google and Bing.
