Engraving on mantle surface on a round detail Siemens Sinumerik 840D sl


Engraving on the radius surface on a round detail


Prerequisites in the program are adapted to TRACYL execution:


The simulation program's tool spindle is called 3

The value after TRACYL is the diameter of the part, in this case diameter 70

The cycle should be run in G19 plane

The zero position of the cycle is changed, e.g. X is the same as Z (depth of milling), then from zero that sits in the center (differ from the pocket cycles there) X1 is cutting depth, Y position on the arc, Z is the same as usual

The simulation shows mirrored text, therefore uses mirror writing

Tool "countersink"

Finished program:

The engraving cycle

thread milling inside or outside without special tools

Want to thread mill?
do not got the mill tool?
got a lathe/turning machine?
with a smaller thread turn tool, a boring tool actually.
This tool needs to be a tool for internal lathe, and then we go

as always, show the pic of the tool, this one is from, othervise sandvik
mounth the tool in you mill chuck and your on the go

The tool on the pic is the (only) tool you need

we are going to show how to do it in sinutrain 4.7 (4.07) and cycles.
check the video after the instructions..

Chose a internal tool, called ..:

Threading tool is an option in sinutrain, use that, if you do not know sinutrain, check my other videos.

check the video for the rest, ask on mail for everything else

This work inside and outside, cool or what?

Heidenhain Millplus IT and Tilting the coordinate system in autodesk Fusion 360 CAM with G7

Tilting the coordinate system in autodesk Fusion 360 CAM with use of G7
Heidenhain iTNC530 should be on the same principle with Cycle 19

In the CAM-system, when you are about to tilt work plane for 4-5 axis machining, you need to use the right tool-coordinate system to make this work.
I use this rule to tilt the coordinate system:

(Right hand rule for axis orientation and direction. (R. Hewitt,

The G7-code in this machine has 3 axis to tilt around  A5, B5 and C5 as X, Y and Z axis, in that order and that make A5 to mill on the Yside, B5 to mill on the Xside and C5 as Zside (damn that's weird..)

(From the millplus IT Ver 5.20 manual)

As mentioned in an erlier post about tilting  the sides has different coordinate systems.
In this case we will use A5=90, A5=-90 for the Y sides, B5=90 and B5=-90 for the X sides to cover all the sides

All the facts of the CAM in fusion:
Use the pen-shaped button on the upper left.
Find setup1 and setup1 again and the 4 drilling operationsbut you will not see the tool coordinare system, only the tiny marking for the tool position, Download and use your Fusion 360-program to check this out
We have now totally 5 coordinate system to juggle with, nice

The CNC-code:

N1001 (1001)

N62 M9
N63 G74 Z0 L1
N64 G7 L1=1
N65 M30
(my G74 needs to be Z-10 to work)

Every G7 has one active value if you'd choose the correct  coordinate system when Fusion 360 posts the code.

This video shows how your chose should be done.Take note on how the coordinate arrows are placed on the tool

Back to the CNC-code then. I did a test of the code, it works the way i like it to work. There may be a lot of other ways to do this, I'm not an expert at all, I'm a noob on this, just started.

We will check the video out, I didn't use a proper work piece ant tool for this, just something as reference. The height depends of the lack of proper fixture for this type of machining in my DMG DMU80T.
Often, I do not use a edge finder and a bottle of windows cleaner when I'm milling, trust me on that :)

This was not a completely linear description of the solution, but some input on how to do it.
I needed to get this on paper for my own sake, hope anyone else can learn from it.
Comment below if some thing is wrong, smart, stupid or anything...

Drill/mill on the diametric part of the workpiece in Lathe (tracyl) Siemens 840D sl

Drill on the diametric part of the lathe workpiece(G19)
How it’s done,
Y Rotation (Much more on this later)
Z Distance in longitudinal (standard Lathe Z direction)
X depth (Diameter-dimensions).
Starting codes:
Besides the usual...
SETMS (1.. 4); The number of the driven spindle
TRACYL (50); Choice of machining on the diametric surface and diameter of the workpiece

Y will be the length of the diametric surface in mm or Inch. (the rotation)
For example, if you have a diameter of 50mm, work out the perimeter and use these dimensions, 50xPi = 157,07963267948966192313216916398
This represents a whole 360 deg turn, use this for a suitable split values between holes.
Example of 4 holes around a 50 detail

N41 SETMS (3) (Enable driven tool, number may vary)
N42 TRACYL (50) (Enable milling diametric surface, dia 50)
N50 G97 S2000 F100 M3
N60 G0 X55 Y0 Z-20 (starting hole at 0 degrees)
N70 G1 X45 (drilling)
N80 G0 X55
N90 G0 Y 39.269908169872415480783042290994 (90 degree hole)
N100 G1 X45 (drilling)
N110 IS G0 X55
N120 G0 Y 78.539816339744830961566084581988 (180 degree hole)
N130 G1 X45 (drilling)
N140 G0 X55
N150 G0 Y 117.80972450961724644234912687298 (270 degree hole)
N160 G1 X45 (drilling)
N170 ................
SETMS (1) (Switch to main spindle)
TRAFOOF (return to normal turning)

Make a PWA-app for windows

Theres an other way to present your website than the web.
You can use a app format called PWA, Progressive Web App.
All the app content made in the form of a standard webpage, easy changeble.
The app can be made for windows, android and IOS.
I made a guide how to make PWA's with Visual Studio (it's free)
The guide shows ho to make a windows version app and how to publish the same to Microsoft Store
You'll find it right here
I can even make you the apps for some bucks, ask for that.

windows apps for NX CAM, mill and turn

After a long, long interruption, got a heart attack at new year... (start getting old)

Made windows apps for NX CAM, mill and turn.
Finally got it to work all the way from Visual Studio to MS Store.
They are on Microsoft store, free and for everything, x86, x64, arm (not xbox, yet)

For the mill part microsoft store, CCG NX CAM Mill

For the Turn part microsoft store, CCG NX CAM Turn

Try it out and post feedback here, I have not really tested them myself :)

DMG DMU 80T, how to use

Made a guide of handling the DMG DMU80t Machine.

It's still in it's rough state, need a lot of editing

try it, give comments on the error I made.... (none of them done by me ofc... :)

you will find it here
