Are you picking the surfaces that you want to machine as flowline surfaces?
Well, thats not the case how you should do.
You need to create a driving flowline surface (Inside or Outside your port, what ever the case may be)
and this surface will direct your toolpath pattern.
Seems like you need to have a surface model of the shell and do a 3D project with the cutter you intend to cut.
Then save to toolpath as geometry.Then after that use that geometry and do a 3D contour Operation.
I used Kluber ( Made in Germany) A Very expensive! grease for our Japanese HSM Center.
It is made to overcome such situations.
I never greased my machine as recommended by the manufacturer( which recomends couple of weeks or so many thousand hours).
Rather I pumped little every few days depending how I used my machine. My work envelope was proportionally small and long cycle time. On some situations I have even pumped grease during machining of my part.
Today reading your problem I exactly realised that I could foresee and I can say why I did this to my machine.
In SurfCam u can copy toolpath/s from one session and instantly paste in other session.
Mastercams Software engineeers should be able to do this I suppose if they want.
There is the basic color pallet but the 256 Color pallet gives more colors/shades.
Do your own exercise , pick and practice the available colors. You'll develop a taste for few and they will become your favourites.
You can also customize shades and store them.
Customize tab is on top.
Colors that I dont use in Geometry:-
Red-Its a MC change color
Yellow-Its a selection color, Rapid color
Purple-Its a MC change color
White-Its higlight color
Black-Screen background
Every color is customizable though in your config.
You can switch these lines off from your config file (same as f9) and use the grid instead.
Grid is visible with your current WCS where ever it goes.
WCS axis marker is another little good idea.
What Gaijin said about softwares supporting it. It is similar to posting a 5 axis simult program without TCP active in the machine , where the CAM system and post takes into account pivot point and outputs pure xyzac for the repective machine to read and run.
Its possible thru CAM system, no doubt.
What I mentioned gives you continous spiral move,starting 2" circle and ending 2.5" circle.
No air move in the middle.
No Trimming required.
Hope you tried.
Kunfuzed, It is possible with the same circle mill you talked about.
With 3/8th cutter for eg.
Rough Tab=tick
Step over=10%
Helical
Min R 100%
Max R 200%
XY 0.008"
Z 0.010"
( play with these numbers to get what u want for ur need)
In the first parameter page, do not need to tick start from center.
U are not using computer/wear/control. Use Centre as u are using already.
XY allowance should work for you. Mention Left or Right what ever side u want to offset.
Thats MarkV said so.
To GCode
""Purge? How do we do that in MC? Where is the command? ""
""right click in the Level Manager""
Still cant find this "Purge " thingy!!
Can any one suggest about this command, where to find in MC.
