hey guys

i was sitting here in minimum wage land dreaming of all the nice little expensive goodies my car would be sure to enjoy, like a nice big port, a supercharger, air conditioning, and as i was popping another part into the CNC lathe and i thought, "hey, that mill over in the corner could do ports on housings pretty good, all the human interaction that would be needed is some finishing and deburring by hand... that would make it much easier and cheaper and more accurate" anyone have any ideas? anyone know how to draft the programs for these machines so we could maybe run a test port, anyone have any side housings they want to donate to a good cause? any ideas, pros, cons, etc? i'm going to talk to my boss richard on thursday about this idea.... i'll keep you guys poosted?

Bolox

sorry to be off topic...
but what do you do on the cnc lathes?
im studying them in part of my uni course now,

anthrax

Is the mill programable?

If it is how is it controlled?

where do u work that they're paying u minimum wage to run CNC. my job started me at 9/hr as an operator. little over 2.5 yrs later, i've learned to do setups and programming and also been promoted to supervisor for a month now @ 11/hr. anyway, yes anthrax, it is programmable and depending on the brand, uses EIA programming language. we have a Mazak lathe and only uses Mazatrol language. G and M codes tell the machine what to do and x,y and z tells where.

example:
basic drill prog
2 holes, 1 tool

M6T2
G90G56
G0X.46Y-1.25M3S3000
G0Z0
G81Z-.58R0F10.
X1.5
G80
G0Z10.
X0Y0
M30

note: the feed rate i used here is much faster than use for milling metal. where i work, the materials we use r composite materials consisting of resins and fiberglass compressed to form a sheet. other materials r nylon, delrin and some paper based materials. so feed rates we run r pretty fast.

glad to here bout the new job, i think u'll find it will come in handy once u learn more about machining and if it's possible where u work, be able to do ur own projects like brakets and such that u can make for ur car. there's lots of money to be made in the CNC operator/programmer field, depending who u work for. use that company, like i am, to learn as much as possible, learn to do setups, get a list of the codes, in fact, i copied a list onto a floppy and put them on my comp, if u want i could send them to ya. what r the brand of machines u have there? any Mazak? the models here is a VTC 300(mill) and the lathe is Quick Turn 200. the other mills r Robodrill with Fanuc control.

M6T2 = Change tool / tool 2
G90G56 = Absolute Positioning / fixture offset 3
G0X.46Y-1.25M3S3000 = Rapid to x and y position / Spindle clockwise / 3000 RPM
G0Z0 = Rapid to z axis zero
G81Z-.58R0F10. = Drilling canned cycle ? / to z depth / retract to z zero / feed of 10
X1.5 = next hole location
G80 = cancel drilling cycle
G0Z10. = Rapid to Z location
X0Y0 = Rapid to x y location
M30 = End of program ( Rewind Tape)


Based on standard Fanuc code. How close am I?

One question though, would you not drag the tool tip across the part going from the first hole to the second? Or is Z zero above the material face?

Here you go. If you happen to have a acromatic 1200 control on a Cincinnati. This is the program for the coil bracket you can see in the "Race Car" section. Or if you are good - you can mod this code to extract the fucked up proprietary codes and replace them with the codes needed for your control. Have Fun.

That's the program for this:

?

AWESOME!

Now all I've gotta do is find a CNC shop that can pull this off!

acromatic 1200 control on a Cincinnati...hmm..

Thanks!

i knew there were those that knew it. as for ur ?, no, we set Z0 at .100 above the part.

Any CNC Shop will know what to do with the program listed above.



To get back to the question in the first post.

The porting done on the ports is 3 dimensional and "undercut" from the side of the housing. You would need a 5 Axis CNC machine. A full 5 axis CNC in going to run you 400K. You are not going to be able to do ports on a standard 50K 3 axis mill.

Now lets say you have a 5 axis machine. You have 2 choices to program a port. A) you hand port the housing and use a "Probe" on the 5 axis to probe the shape and export it as geometry or NC program. B) Model the port in a CAD software and then program the machine with a CAM software.

You are not going to hand write a program to port a rotary. Now - You could if we are talking about a Peripheral port.

I used to run a manual mill. Yall make me feel so inefficent. But ill be damn if I CANT hold a half thousands. Used to bore rods and pistons for Ingersoll Rand.
