a disclaimer may just be in an earlier version of NX, in NX7.5 this is this for real
NX can be a jerk if you do manufacturing on a workpiece where the CSYS (model zero) are "misplaced"
If you going to avoid that, make the model zero correct for manufacturing from start.
applies for both mill and turn (more on turn below)
check the video
BUT,(maybe an old prob, NX 7.5 do this, can't make it in NX11 now for some reason)
revolved turning model workpiece work a little different, you should do your model with X as the center axis (usually Z). When you enter manufacturing, like magic, it transforms to Z as it should be....
If you will start with a model with the Z-axis as i "should be" good luck, you got manufacturing with X as center axis, totally wrong and hard to fix at this level. Can do more on that, ask!
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
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 indiamart.com, othervise sandvik
month the tool in you mill chuck and you're 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 an 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 by mail for everything else
Tilting the coordinate system in Autodesk Fusion 360 CAM with use of G7
Heidenhain iTNC530 should be on the same principle as Cycle 19
In the CAM-system, when you are about to tilt the 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, ManufacturingET.org)
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..)
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 operations but you will not see the tool coordinate system, only the tiny marking for the tool position, Download and use your Fusion 360-program to check this out
We have now a totally 5 coordinate system to juggle with, nice..
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 choice should be done. Take note of 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 workpiece ant tool for this, just something as a reference. The height depends of the lack of proper fixture for this type of machining in my DMG DMU80T.
Often, I do not use an 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.
