No, I haven't... Blade, eh? Interesting. Do you have some "secret" module installed? What version are you using?

Thanks,
 
It's a hidden config option developed several years ago for Siemens I think. Our company was slightly involved with the testing. It's designed for very simple turbine blade shapes. Be careful when using this option as it is very buggy and can cause sequences to fail that don't even use these milling types. I can't remember the option name right now. I will look it up later when I can get to my notes. If you scan your config.pro file you shoul be able to find it. I think it has the word "blade" an "rev_20" in it
 
This was indeed developed in conjunction with Siemens. It is a hidden config, and provide some specialized machining functionality for production machining of blades. I think PTC did not open it up for general con sumption because it is very specialized. So, unless you do similar work, you do not need it.


Hub Mill is basically almost like Swarf Mill sequences. So now since we have Swarf Mill, I do not see areal need (maybe it is a bit more specialized, but Swarf can do almost the same thing).


Blade rough is an interesting toolpath though. It is like an automatic volume sequence, but much faster to set up for blade type geometry. It uses a new type of mill surface called Approximate shape which best fits a rudimentary shape efficiently around a blade.


Additionally, this hidden config provide additional control for leading edge tool cutting when in surface mill sequences.
 
No dear Hub Mill is not like a swarf mill,


Hub milling is actually similar to Trajectory Milling in the control it provides the Programmer over the tool path. The Programmer selects the tool drive surface and the height surface. Tool axis control is automatically generated through the vertices of the hub or shroud, while providing the user the ability to add or remove axis definition.

Thanks Sohail,


Your copy-paste is from a document I wrote 6 years ago.


We are splitting hairs here: whether it is closer to trajectory or swarf mill. The way the tool is placed on the surface for non-developpable surfaces is actually like a swarf mill sequence. Although it has the special automatic tool axis definition that was needed for blades.
 
Hi all
the config option for blade rough and hub mill is

MFG_R20_BLADE_MILL yes. u need to manually type it
 
And friends
please never switch this option on and work on ur any other nc sequences,
it affects many other options adversly.
for example we cannot specify an approch wall for window machining while this option is set to yes in wf3

Take care
