NX video help

Check out the NX video guides I'v made
I made them for Siemens NX 7.5, but they seems to work with NX11 with some minor thing that have new/other icons, moved functions and so on.
The guides covers both turn and mill, includes threading and simulating.
There are'nt any narrations och voiceover on the videos, just quiet hard work
You can get those on the website or in an android app, your choice :)

G12.1 driven tool in fanuc lathe

Code G12.1

If you are going to use a driven tool in the lathe (turning) you need to have a machine with C-axis capacity and of course, driven tools.

You got to tell the machine that you will use G17,  edge plane, the front of the turning workpiece (the radial surface is G19, the normal turn is G18)
G12.1 make your lathe to a milling machine.
Code with explanations

O1111 
N5 G10 P0 Z-100 (Workplane, zero point)
N10 G28 U0 W0 (tool change position, same as G53..)
N15 T0707 (tool change)
G0 Z3 X40 (start point for X, sensitive setting!) 
N20 G97 S800 
N25 G94 F200 
N30 M52 (start c-axis) 
G0 C0 (zero c-axis, same as start point in X) 
N35 M13 (driven spindel tool M3) 
G12.1 (milling) 
G1 X0 C9.5 (start point for the circular mill) 
N45 G1 Z-3 (go deep) 
G2 X0 C-9.5 R9.5 (circle/2) 
G2 X0 C9.5 R9.5 (circle/2) 
N50 G1 Z0 
N55 M30 

Programing in G12.1 in most machines make you use a standard mill programming on the face of the turning workpieces.
The coordinates are in this case, X and C (as Y) and Z
X has got its half value (diameter to radius)
C has its real value (same as Y in a mill program)
Z has its real value (depth value, as a mill program)

You need to make a proper start point before the mill programming.
For X and Z, before G12.1
For C (Y) after M52 (C-axis dependent, use before G12.1)
You may get the error "going through pole" otherwise
that error reveals itself when the programming you make is impossible for the machine to do, try another tool path to solve this

To leave the mill setting:
G13.1 (milling off, return to G18)
M53 (C-axis off)

Are you interested to learn CNC or/and CAD/CAM
I've made some tool that will help you to make knowledge in this subject much greater.

CNC Coding Guide will educate you on CNC and CAD/CAM. 
The site contains instructions, videos about the making in both subjects, android apps for a easy way to get your information close and writed guides that help you learn CNC and CAD/CAM.
As a bonus the site contains both a online CNC simulator and a CAD/CAM software
