[Design and Technology] Information on CNC

[David Pitt]

I’ve worked at a school that had one in the past.

The pro:
You can definitely do some things with a CNC that are difficult, or painstaking, with hand or jig routing.
Once you learn the basics of Vcarve or whatever software, the entry level stuff kids are likely to need to do is pretty easy to accommodate.

The neg:
It was noisy – it needed a separate room from the rest of the space, acoustically insulated.
We really needed to have a technician to queue up and coordinate jobs, as it got a lot of use over time
The changing of bits, maintenance and so on was a bit of a time-eating proposition.

Overall:
If you can get one, it’s well worth it.  For 4k you might struggle though, as cheaper ones tend to fall out of alignment and calibration easier and that’s just a bigger headache over time.  Did you have a model/brand you were thinking of?

Cheers, and good luck.

Hi everyone,

I was wondering if anyone had an insight into having a CNC router at their school they would like to share?

My school is looking at purchasing one and has around $4k.

I only have limited experience with CNC that I got at TAFE

I simply want one that i can do some small things and hopefully work into a project or two.

Thanks in advance
