NX turning, NX 7.5 CAD/CAM and later, whole course, for free

NX Turning, Manufacturing in NX

Made a website for the Turning part of Siemens NX training.
It's the same as the mill part but adapted for turning parts and includes threading, there are also some video instructions attached to this instructions that will explain the work thoroughly.
It shows file management, sketching, model (Solid modeling), tool handling and manufacturing.
It's free to use.
It fits (most parts/tested in) NX6, NX7.5 and NX11

You will find it at

Made it from some wierd conversion site, word to html, it may be funny in some parts.

Made a new apps for android.

This apps are the same as the mill and turnin training material made for NX n a easy to use format,
You will find the mill app right here
You will find the turning app here

please comment the abow, need feedback so I can make those resources better and more useful.

NX 7.5, converting units, inch to mm, mm to inch

If you got a model from internet, 's library or from some other source, you may end up with the "wrong" units on your model.
In NX 7.5 there is no drop down menu to make a unit conversion between metric and imperial units.
But there is a way anyway. In NX they did add hundreds (?) of DOS-programs that works like drop down menu command, but they did not added them the drop down menu object in the NX program.
If you'r familar to the CMD-command promt, go to the picture, otherwise follow the instruction.

Go to Search in windows, You got it down by the windows logo (start menu)
Write CMD in the search, click the Command promt that appear.
Now write C:\program files\nx 7.5\ugii\ C:\cadcam\model.prt -mm and enter
the "C:\cadcam\model.prt" should be you own part name and folder and "-mm" the conversion you want to preform I assume that you use -inch if you'r going that way, but I'v never tested this.
see the example down below
I'm sorry for the "too big" image, but it's hard to see othervise, I hope that this doesn't kill the layout on your mobile unit

NX 7.5 CAD/CAM and later, whole course, for free

I'v have a week with a basic NX 11 CAD/CAM course, the newbie one.
So when my student are doing their training on theres computers, I got some free time for my own work.
I created my training instruction as an online version, just for you(!!!). with both CAD and CAM, it's the one I use when I educate in CAD and CAM
It's a well-utilized time. (?)
Because I am a bit lazy I used Words translating tool to translate, so the language can be somewhat rough, please comment on things I missed and things that wrong linguistically.
It fits NX7.5, but most of the content fits even NX11
Use it for free even for professional use (It can't be wrong to paypal some $ if you use it to make money for yourself)
Do link my blog or webpage.

I hope that you find it useful
==>NX Milling instructions<==

More of the same will come later, NX turning, fanuc basic course, siemens 840D basic course, Millplus IT basic system. just wait :)

just videos, the week...

This week, lot of progress

For my students, they learn a lot.

Check out his weeks videos:

My own pleasure:

Make a comment or a complaint, ("-do not do it that way" and so on....)
We can take a discusion about everything, I'v got close to 35yrs in this, I know a lot, but not everyting so your comment can make.. me to relearn? (or not :)

have a nice weekend ppl !!!!

made a *caugh... caugh* small error

Can happen to every one!

Yehaaw, made it, in front of my students...

I do not think it's a problem, misses in CNC programs and manual manufacturing happens all the time, just wait. it's this that makes a good CNC programmer/manufacturer, try hard to do, try and .... fail... the first time, but then, finally, on the mark on every makes a good and thoughtful programmer, as a mcahine'/workshop owner you need to let this s..t happen, it makes you worker better to earn your profit...
I know, 30+ years in single part machining, I done this, not every day but close.
Nothing can protect you of this (If you not have exeptional clever or lying or lazy personal)

Don't kill your machines to much and do not abuse to much cutting tools, you'll be fine :)
It is part of the development of a future expert

BTW, be carefull!! (closed doors, all security locks on its place)

cheap action cam, worth it?

Bought a cheap 1080p action cam

Are those any god? the Gopro5 I was using was "murderd" by some one, the case is broke, can't be fixed according to Gopro, they don't repair their cams. You need to buy a new one.
The Gopro has done a good job with good results.

Did'nt use action cams much so $400 for a new one, not a chance..
Bought a $30 cam instead.
Did edit it in 720, din't made anything much different
Check the video from the $30 cam

I don't have a good Gopro video from the 5 version to show, but we did a video with the gopro4.
Watch it and see if there are any differents..

I know that the cheap cam has no good close up/macro function and I did go close when filming
But for $30?
farly good I think
The actioncam got wifi and a pretty good app.
What cam then? it's a Rollei actioncam 372.
I'll try it more and present the results later

It's later: the water resistance plastic case has no chemical resistance what so ever, using it with cooling fluids make the plastic to crack and it falls apart, useless

Milling in lathe, siemens sinumerik 840D

If you got driven tools in your lathe, try this
Mill in lathe, on the edge of the workpiece.

milling in lathe
If you can't see the moving gif, check my youtube

Raw code with comments:

N10 G54
N20 WORKPIECE(,,,"CYLINDER",0,0,-100,-80,200)
N30 G0 G53 X400 Z600 D0 (safe position, tool change)
N40 T="FRÄS10"
N50 M6
N60 G94 F100
N70 SPOS[1]=0 (set chuck (workpiece) to 0 degrees, need to be before SETMS(1) )
N80 SETMS(1) (set work spindle, driven tool)
N90 S1000 M3
N100 TRANSMIT (start G17, end plane milling)
N110 G0 X70 Y35 Z3
N120 Z-3
N130 G1 Y-35
N140 G1 X-70 (value X2 without DIAMOF, program in dia)
N150 G1 Y35
N160 G1 X70
N170 G0 Z5
N180 G0 G53 X400 Z600 D0
N 85 TRAFOOF (return to turning, G18)
N190 M30

How do you do that?
The programming make you able to do a mill program on the edge, see the pictures below.
If you does'nt use DIAMOF (and don't) the X-coordinate will be programmed in the double value, the machine (lathe) use diameter measurment on X.. If you use DIAMOF do'nt forget to DIAMON after the milling, otherwise everything will be interesting when you try to do your ordinary turning afterwards
And don't forget to shut off the milling with TRAFOOF (yep, correct spelling)

Programming, the blue square is the milling in the exemple, Zero on X and Y is in the middle, Z- is down into the picture

Make a comment if you want more detailed explanation! :)
