Hi guys.
I want to design a cnc mill machine. I have to design it's structure (frame), the other things are taken care of. For this I need your guidelines like from where to start etc.. Any resources,links would also be helpful.

First find the loads on the structure.

I'm also interested in building my own as well. The primary concern with every diy CNC machine (IMHO) is going to be a balance between cost and capability. Cost obviously being how much money you're willing to put. This directly translates to your capability, which mainly consists of what materials you can machine and what resolution you can machine it too. Because everything in series will deflect in series, your resolution will be highly dependent on what linear bearings you use, their deflection, etc.

That being said, what is your intended application? PCBs, foam, wood, fiberglass, aluminum? Also what size of each axis are you looking for? e.g. 12"*5"*3"?

This will be the driving factor in your design, hardware, and cost.

A good start would be to try google first. It doesn't seem like you've put too much research in yet, but there are dozens, if not hundreds of documented, open source, and even full CAD downloadable designs already out there for the full range of applications.

Hi guys!
Thanks for your replies.
Actually I've 3 linear actuators. I am going to use them as usual for x,y & z axes. And the Z axis will be on a gantry. We're going to use the machine as CNC laser machine. The size is approximately 4 feet x 4 feet x 5 feet. Can you please post or mail the google links?
It would be nice of you!
 

1. What is a CNC mill machine?

A CNC (Computer Numerical Control) mill machine is a computer-controlled machine tool that is used to create highly precise and intricate shapes and designs on various materials such as metal, wood, or plastic. It works by using computer-aided design (CAD) software to generate a set of instructions that control the movement of the machine's cutting tools.

2. What are the main components of a CNC mill machine?

The main components of a CNC mill machine include a spindle, cutting tools, worktable, control panel, and computer software. The spindle is responsible for rotating the cutting tools, while the worktable holds the material in place. The control panel allows the operator to input commands and the computer software controls the movement of the machine.

3. What materials can be used with a CNC mill machine?

A CNC mill machine can be used with a wide range of materials, including metals such as aluminum, steel, and brass, as well as wood, plastic, and composites. The type of material used will depend on the specific machine and its cutting tools, as well as the desired end product.

4. What are the advantages of using a CNC mill machine?

There are several advantages to using a CNC mill machine, including increased precision, faster production times, and the ability to create complex and intricate designs. Additionally, CNC machines can be programmed to repeat the same process multiple times, ensuring consistency and accuracy in production.

5. What should be considered when designing a CNC mill machine?

When designing a CNC mill machine, several factors should be considered, such as the size and weight of the materials to be used, the type of cutting tools needed, and the desired precision and accuracy of the finished product. Additionally, the design should take into account the speed and power of the machine, as well as the necessary safety precautions for the operator.
