What kind of machine should I use?

[Eusk]

Hello all, as you can see I am new here but I had been looking around for almost a year in this forum and in others, wondering wich option could be the best for the work I want to do (view the attached pic). This type of work is all over my rococco-style-town in wood or stone. So when I first lear about CNC machines I think this could be a way to do moust of the job.
So my question is what kind of maching sholud I aim? It is possible to do this with a 4 axis Router or it sould be a granty head with 5 Axis like a mill ( harder and very spensive$$$)

Any suggestion?

Thanks in advance

This calls for 5 axis with high precision tooling. I hope are ready for learning curve. You have said you have been here for almost a year? Keep on reading and see what others are doing. As per price tag? 5 axis ready build = $$$$$$$. And I hope you have skills hombre.

Holey undercuts in anisotropic material that warps Batman!

I don't think anyone makes lower stiffness 5 axis machines. You wouldn't need the stiffness of most industry standard machines for wood, but you'd need the DOF. Maybe you can do it on a 3 axis mill with a 2 axis rotary table, but figure spending around $25k for a decent used 3 axis mill (maybe doable on a 3 axis router at $3k) and a whopping $40-$80k on a two axis rocking table.

Legit Solidworks license: $6k
Camworks: $15k

If you're not averse to having an unfinished part, you could do most of the roughing on a 3 axis router with the rest of the undercutting work with chisels or a good micromotor. Call it a $3k router to make a 1'x1' sized panel 8" deep. CAD/CAM at $8k (Solidworks + Sprutcam) and a really really magical CAD guy to model it all. Perhaps you can do a mesh of points on an original part which would end up getting all the data you need for 3 axis roughing without having to hire a very expensive 5 axis CMM.

If you want tool changing, you'll have to go up to a decent used mill with tool changer.

Not a bad idea if you're making a lot of these parts. The roughing would make the hand work go a heck of a lot faster and you'd scrap a lot fewer attempts.

I did not want to discourage guy, but I my thought is the same.

Sorry for the late response I was away and then a very bad year in the bussisnes and then holy days, etc.
Thanks for the advice, for what you writed here, my first step will be, to be avaible to make the design in a cad/cam software, I had Rhino 4 with RhinoCam, this shold be it (With a lot of thime in the computer), don´t you think?
Im thinking in making doors and cabinets doords in the begining, not a lot of pices, but thinking in a high market with fine woods. Starting as a side bussisnes and who knows maybe in the future something more. Your idea of using the 3 axis for doing the roughing and finish as posible and then using a micromotor for the rest is very good Thanks!!

I am in the bigining of building my first Router, may be you can help me with this, the measures are 3 meters-3.3 yards- X 2.5 meters-2.7yards- (X and Y axes) and 25cm (10 inches Z axe) with a 3 hp Router and the following stepper motors:

NEMA 34 HIGH TORQUE STEPPER MOTOR 906 oz-in (X Axe)
6.1A, Rated Voltage: 2.1V (in Bipolar Parallel)

NEMA 34 HIGH TORQUE STEPPER MOTOR 640 oz-in (Y Axe)
Current: 6.3A, Rated Voltage: 2.3V (in Bipolar Parallel)

NEMA 23 BIPOLAR STEPPER MOTOR 425 oz-in (Z Axe)
Current: 2.8A, Rated Voltage: 4.17V (in Bipolar Parallel)

Unregulated Power Supply 1000W, 50VDC/20A , Input:
120VAC or 230VAC

C-10 Break Board (In the future a 4 axis)

What do you think, am I in the rigth path??

Thanks for your coments

Build your machine and you will see how much dinero you invested.
NOW translate it it into product price that you can feed your family and count on saving money to buy materials, tooling, new machine in some time, ect.

This way you will go in right direction, do the math first before you dish out money for machine. learning and legit software. I earn honest $, work hard and sleep well each night.
I hope you get the point.

Here I send you more designs

Sorry, I do not get the point. What do you mean??

[Big-tex]

Do you own legal copy or Rhino?
How much you in ted to spend building or buying machine?
Answer those simple questions first porfavor!!

[Big-tex]

Let me make it simple.
Rhine $995 = 12835.5 peso
CNC $2500 = 32250 peso
total = 45085.5 that is before you make anything
lets add bit more

matrials (wood=madera)
tools-cutters
design and study time
your machine will break and needs repair $ needed for repair parts
time spend looking for customers
making samples to learn and show customers, broken bits while making them
_________________________________________________________________
all this added + profit= product price


NOW!!!!! Big question do you want to make minimum wage per hour?

[Eusk]

Yes I own a legal copy of Rhino, for rhino cam is the evaluation version for know. For the machine I thinking of spending around between 800 and 1000 Usdollars. Electronics 700 Usdollars
For all with out the rhino software that all ready own I will spend around 3000 usdollars.
I own a factory, more than 5 houses and comercial buildings and I live very well, every time I go to Us I spend in your contry over 10,000 usdollars, Not all people in Mexico buys pirated software

As I told you, this is in the bigining a "Hobby" bussisnes expecting to grow. Cool it man, I am not looking for stealing you job or some one else job in Usa. I know this is a forum to help each other. Be nice
