fbots:::The future of Robotics




Hi,
For the past one year we have been working on CNCs. After lot of research, we have finally planned to make available very low cost CNC machines in India. These are hobby class machines, prefect for making your own kits.
There are two types of machine we make:
Milling: To cut Balsa and ply
Hot wire foam cutting: To cut foam
The most important factor is the cost. We are working on the cost and trying to reduce it as much as possible.
For estimation, we can say it will be cheaper than any other machine available in India or world.
It can also be modified to laser cutting.
We manufacture on order.
Exact details and price will come soon.
For more details contact me:

Happy is a man whose hobby is his profession



I think it would be very difficult to get a CNC machine under a lakh. But may be a mini hobby lathe is possible. Really interesting news posted by Amir Sir.

Sir ji...Would love if you could reveal some information about the size, cost etc. Is it the same one that are found in many mechanical labs in engineering colleges..dont remember the brand???

AFAIK, Amir has been DIY'ing hobby CNC similar to those on hobbycnc.com. If I can guess right, it should cost around USD 1000, if Amir could minimize components from the West and use more of recycled component from large Printers etc.  But it would better answered by Amir himself.

Kudos Amir. Its should one of the first DIY CNC by an and Aeromodller in the country. Do share more information how it is doing for Balsa. Any plans to produce 'Short Kits' ? Rajib on this forum was planning but guess he is stuck with short supply of Balsa and high TOC of Laser cutters (you need at least 100W laser for clean, burn free cuts on balsa.

Thank you friends for your respnses.  Smiley
as said by Ujjwaana sir, i have been working on hobby class cnc machines from last one year. i bought the driver board hobbycnc. Currently we are working on driver board, we are trying to make it here in India to reduce the cost. The concept/design of router is ready.
@Ankur: There is a huge monopoly in machines market and that is, on increasing the cutting area, the cost rises in approx same ratio, and that makes a medium size machine very expensive. But actually on increasing the area, the cost has to rise a fraction. We will take care of that and accordingly cost of a medium size router will be much less that what is available in market today.
The cost will be a few thousands, not in lacks.
We are trying to reduce the cost of medium size machine to around 50k-60k including everything.
Exact price and details will be available soon.
Suggestions are invited.
Thanks

I need 10 days time to finish my work and post pictures of machine and sample cuts.
Sorry for the delay.

Theoretically it can cut upto its Z axis travel, but there are certain limitations of the cutting tool we use.
But it can easily cut upto 6mm ply, and that is sufficient for out work.
It doesnt mean you cannot cut more than that, but for that yo have to design the G code with the help of CAM softwares, which is in itself a tedious job.
And the cutting speed will also depend mostly on the cutting tool. The machine will give you maximum speed that is compatible with that tool.
More details will be uploaded soon, as our work is progressed.

sounds very promising, is the macine programmable independently or does it need to be interfaced with a CAM software to do so. A complete catalog would be very helpful.

I will try to explain the programming methods.
I m not a pro in CAM, so correct me if needed.
You will be requiring three softwares.
1. Designing
You can design your job on autocad, paint, photoshop or use image, DXF, etc files. We have support for nearly any design file, Also 2D design can be converted to 3D.

2. CAM(Computer Aided Manufacturing)
CAM software is used to generate Gcode, from the available design file.
There are some basic softwares like Lazycam, which is relatively easy to use, but it lacks 3D milling. You can do single passes, thus you can cut 2,3,6mm thick sheets, depending on your router capability.
For thicker sheets, you have to do multiple passes. Although its supported in Lazycam, but i personally didnt like it.
I m using Meshcam, Its a basic CAM software everyone can use. But i havent tested on very complex milling jobs.
But yes, nearly all hobby works and shape cuttings can be done on meshcam.
There are some more professional CAM softwares like solidcam, Gibbscam, autodesk inventor addon, etc, which are used in very detailed and professional operation, so we wont be needing them, unless you are designing something like automobile parts.

3. Machine controlling
This is a software to control the axises of machine with the generated Gcode.
It sends the signal to stepper motors and toll moves accordingly, cutting the desired job.
Most commonly used software is Mach3

Answer to Husein sir's question.
This machine i like any other cnc milling machine, you can control with any software of your choice.
We are not providing separate software, neither is any difference in programming techniques. Its all the same standard method.

what type of file format is supported by this machine i mean .cdr, .dxf, .dwg for cutting purpose & also what cutting motor (router) are you using on this machine.

As i wrote on my previous post, the machine has nothing to do with the file format.
The software you are using will be responsible for supporting the formats.
But generally every file format is supported by one or other software.
Therefore format is not a problem.
Regarding the cutting tool, you can use any tool available in market. Dremel is one of them. Some other brands are Bosch and Dewalt.
We would be providing mounts for the most commonly available tools so that you can mount anyone of your choice.

Amir,
People like me are dying to see your machine at work. even shots of prototype stages, when things go wrong time to time is fine. There are so many scratch builds around here who so much appreciate such grand effort.
Please do post some pics if it does not bothers you about propriety stuff.
