Is it possible to get the correct output for helical moves without loading any kinematics from the machine model?
Create post with a generic "5-Axis with Dual Rotary Tables"
4th Axis ZX B
5th Axis XY C
Using OOTB setting (ie using new iks)
The post outputs helical moves hole milling at any angles.
With no machine model loaded the output is safe and correct.
With a machine model loaded and the C table axis is not in line with MCS Z axis the posted output is FUBAR
set mom_kin_iks_usage 0
Post only outputs helical moves at B0 and B90.
All other helical moves are output as small linear increments
With a machine model loaded in any orientation output is safe.
Any help appreciated
NX220.127.116.11 MP15 & PB9.0.3
I am using generic 5 axis posts like a core for all of my posts. the best.
Ive noticed that NX11.0.2 doesnt output helical moves if operation is in some angle.
I am not using ISV and get output in lines.
I reported this on GTAC. PR 8930075
If you dont want overide kinematics from simulation model puts "return" into the top of PB_CMD_reload_iks_parameters.
Adding return or not editing PB_CMD_reload_iks_parameters is effectively the same.
This leaves the new iks usage enabled.
I want the output from post with new iks enabled when there is NO machine loaded.
Many of our older parts have one workpiece body/component & blank with multiple MCS's in different orientations for OP1 OP2 etc.
Adding a machine model to these and then posting is a recipe for disaster.
As far as I can tell there is no way of telling if a machine model is loaded in the post so it can be aborted.
I always use table-table for any 5ax machine. do you think there is some problem in this logic?
Because Ive never met som troubles with this. Can I face some in the future?
Depends on how you output data, and the types of operations.
If all you do is 3+2 machining, and use G68 (or CYCLE800 or whatever), you should be OK
If you do full 5 axis machining, you may not (depending on what options you use).
I would tets full 4 / 5 axis motion & see what happens
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
It seems to be OK, I am using it for years (HT,TT,HH).
Maybe there is something... but really dont know.
