I'm designing a CNC machine how can I input the design data into the CNC? Are there any software's available to do so or would I need to program the machine myself to make it give out 3D coordinates and model out the CAD design.?
CNC machines can do their function based on codes (G code or M codes), that can be used to route the tool and give orders to the machine for what to do at each step, for example changing the tool, cutting from point A to point B using tool X and other tasks.
Recently, CAD programs can be used to produce such codes aided by CAM (Computer Aided Manufacturing), so the process loop starts with developing a CAD model then using a CAM software to generate the code and finally CNC machines performs the required machining to get the workpiece as per the design.
Hope I could help you!
The best way to convert 3D design into CNC programs manually is by generating the tool path by layers. This is like slicing your design and working out the tool path for each layer. Alternatively you can use several available software including Artcam, Mastercam, Duct, etc.
I really recommend that you do manual conversion of design to G-codes 9CNC codes) to let you be more familiar with CNC machine programming requirement.
I hope the above answer help you.
Hello Sushant, In CNC(computer numerical control) machine, there is touch probe mounted on spindle of CNC~which is use to digitize 3D shapes. Whenever the touch probe come in contact with surface, this slight impact creates E-switch in the probe. which is sent to CNC unit as signal.
This signal causes the CNC to block movement of currently running processes on machine and record its axis positions at that instant.
Hence the result of converting design data into 3d coordinates achieved. The numerical values of these axis positions represents the coordinates of 3D point.
The best software for controlling DIY CNC is MACH3, but you can use CAM software like Art Cam, Aspire, Master Cam, to generate tool-paths (converting CAD drawing to G or M codes); 3D could be also done with these programs based on either a picture or a vector drawing. Mach3 also can generate G-codes.
Hope this helps you.
Hello, you can design the desire workpice for turning or milling process. Than the design of workpiece in some software (Solid work, NX CAD/CAM, Lazycam) make possible to convert the trajectory of tool path in G-code. Also, the CAD/CAM software make possible the simulation process before starting with machining process.
