Having watched the tech tip videos on post processors I was wondering if creating a post for a Y axis lathe was as simple as it is for the one shown in the Create mill turn postprocessor presentation. Instead of using an XZC linked post I instead create a linked post which is an XYZC 4 axis milling post. Is this the right approach? What about adding a subspindle, does that change anything should I try and approach it differently? Do I need to look at the post in Sim 015 for subspindles?
How come there are no Y axis lathe ISV examples included with NX? Is NX capable of simulating a compound axis such as the Y axis on an Okuma LB3000EX MYW.
Thanks for your help with my many questions :-0
Solved! Go to Solution.
I am not sure if I understand kinematics right but
I would do this:
-link_pp2: xyzc (4axis table) for milling periphery
-link_pp3: xyz (3ax) for milling face
*for compesantion Y0 with C:
-link_pp4: xzc for milling face, init spin. axis 001 (tool z dir)
-link_pp5: xzc for milling periphery, init spin axis 100 (tool x dir) (maybe not necesary because of link_pp2)
And you can choose propriate post by putting operations in propriate method.
(I cant answer isv questions I dont work with them, only posts)
in case the millturn machine has no Y, only XZC:
-link_pp2: xzc, milling face, (nit spindle axis Z, 001)
-link_pp2: xzc, milling periphery, (init spindle axis X, 100)
Note some posts can be shared.
Radial milling (tool axis 100) - you only need the XYZC 4 axis post. IMHO having an XZC only post just confuses things. (EDIT: Note I've never used G7/G107 cylindrical interpolation, so if you need that, you'll have to figure out if you need a separate post for that)
Axial milling (tool axis 001)
- If you feel comfortable doing this, the "XYZC" post can be shared with the radial post (reset mom_kin_spindle_axis and "MOM_reload_kinematics")
- I generally separate the XZC post (G137 mode) so I can automatically turn on G137 (vs. G138) for the user (For those not familiar with Okuma, G137 = Fanuc style G12/G12.1/G112)
Note in PB, if you select a XZC template, there is (or was) a toggle to turn on a Y axis
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
