big budget cnc

[pet30]

the frame could i make it out of 50x50x3 mm or do i need to use bigger and heaver steel?
i found this shop in holland i think the price is ok because i need supported rails of 3 meter long

You need to draw this up in Cad otherwise you will waste a lot on money quickly. What do you mean by "the frame" its hard for people to advise you without the CAD drawing.

with frame i mean the base of the machine,

i don't have cad program just sketchup i am a woodworker so for drawing kitchens etc thats good enough but i can draw very accurate in sketchup

At some point you will need CAD and CAM Fusion360 is good and free

I know people love Fusion but cloud computing is about as secure as my Vauxhall Nova was (Was stolen 5 times lol)

if you're data has no financial potential then use fusion if you data is valuable avoid clouds.

My bank has been hacked twice in 6 years and virgin media last week, I have no faith in secure cloud computing at all.

I know it's time to upgrade my cad so going to buy this package I think

Seems very good value for a semi pro workshop solution.

I like Fusion, yes its cloud but you can save copies locally too. ;)

I've heard Fusion is good but the guys I work with everyday keep telling me to buy solidworks but at £20k not been in the mood lol, especially as they upgrade every year so I would have to go the £5k a year upgrade path lol. I believe Fusion is not free if used commercially but never checked the licensing out because if I did change cad it would be to solidworks as I have never come across 1 manufacturer that does not use solidworks now and I've dealt with injection moulders, vac formers & plastic/aluminium extruders on a daily basis for 6 years.

If I couldn't save locally then it would just be a joke of a program but being able to save locally does not make it secure just at least usable.

You can import files from SW to fusion360 if that helps. Being secure for the average hobbyist is not the end of the world when it is free.

Its hard to find a free cad cam package as good as fusion.

Anyway getting back on track with your build. I would start with the design of router bed first and then decide what you need to stand it on. Or build it all in one piece. In my opinion 50x50x3 is not strong enough for what you are trying to achieve

2 years ago I had to build a punching machine (Hydraulic) for plastic I built it from 3mm box section AND it's not strong enough I have to run it about 1/4 the speed I built it to run to get decent results and I'm punching Polyprop. Any faster and the holes are not accurate! I heat the punchs to 230c as well to reduce stresses using nozzle heaters from injection moulding machines.

I would think a minimum of 7mm would be needed if I wanted to make a steel router.

I was shocked the stresses of punching plastic the aluminium casting we made wasn't strong enough to resist the forces and we had to recast in steel and on the first attempt the steel shrunk too much so we had to recast and grind to fit.

If I had a cnc machine then would have been a lot more fun lol.
