CNC Programming


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.

Investigation

Now we have to investigate the relating methods and topics that possibly help us find a solution. The goal is to find the most efficient way to bring low volume, accurate, fast turn around manufacturing in house. 4 axis CNC Milling/Routing: CNC stands for Computer numerical control. Numerical control is the automated control of machining tools and 3D printers by means of a computer. An NC machine alters a blank piece of material (plastic or thermoformed plastic ) to meet precise specifications by following programmed instructions and without a manual operator. Computer Numerical Control is different from typical PCs in the type of software used to control the machine, which is specially customized and programmed with G-Code — a specific CNC machine language that allows precise control of features like speed, location, coordination and feed rate. A 4-axis CNC machine operates on the X,Y and Z axes like a 3-axis machine, but it also includes rotation around the X-axis, whi...

2nd week

CAM mach3 has a cam software called lazycam so we will be using it to be able to make the Gcode for the Mach3. CNC machine software Mach3 and Mach4 software will be used to run the CNC Machine, also a CNC usb controller software comes with the usb that could also possibly work into the making a router. Design of router: The design of router will be based with autocad, due that was the advised software to use but later on, we will do a research about it Errors we countered and how did we solve the problems: We did the building and fixing of the new CNC machine CNC machine not having a manual, search online and to contact seller No CNC calibration manual, search online and to contact seller Broken Mill needles, the solution will be to buy more Milling needles

Types of CNC used

5 different types of CNC softwares have been used: Mach3, Mach4, USB CNC Controller and PlanetCNC Mach3 Mach3 CNC Controller software will convert your PC into a fully functional 6 axis CNC Controller. Mach3 is one of the most popular CNC Controllers for both DIY and Industrial machines. Mach3 works on most Windows PC’s to control the motion of motors (stepper & servo) by processing G-Code. Mach3 is a feature rich program which is also easy to use. It works with other programs and will import DXF files, generate G-Code, fully customizable. Works with CNC Routers, Milling Machines, Lathes, Plasma Cutters and Lasers. Mach4 Mach4 is completely new software with less than 1% of the programming code in common with Mach3. It was written from the ground up to be expandable, flexible, and extremely responsive for use with very large files. Mach3 was designed for simple hobby machines and still serves this purpose well.  When quality, speed, and the ability to use or le...
