Thank you MillMan.

This is a challenge for me.

I think I am near to fix it.

I'd like try a little more

I get tis error when generating G-codes  :  "ERROR-SETUP FOR PRIMARY OR SECONDARY AXIS IS ILLEGAL"

Good tips 
Thanks

I'll try in real

I have a related question:

for example, we have a table-table(C-A) 5axis cnc, and the spinldle is aligned in the Z axis.

In this case, for 2 & 3 axis operations, for output arcs with G2 and G3, on planar surfaces,
 Is it necessary to change the top-map value from zero?

also in TNC controllers (heidenhain machines) ,  for arcs, we need to add CYCLE 19 or not?

Mastercam have (shift_z_pvt) solution.

It works and fixed.

Hello  

I need to move all Z coordinate in gcodes, about 100mm downer.

I need this for all 3, 4 and 5 axis moves.

I did try achieve that with (saxisz), but not gain.

How can I do that?

Maybe

Thanks

yes , but not working

I put here my 5axis setting

In a post I Have it is set like so...

brk_mv_head  : 1     #Break the 5 axis moves to remove gouge
brk_max_ang  : -40    #'brk_mv_head' maximum angle move, applied if chordal

but I want break angles in both positive and negative direction

Hello
I have a big problem with "brk_max_ang" (breaking all angles)
My machine is a TT 5-axis   CA  (A axis +45 ~ +30)

my post just convert the angles between A+45 to A0 by 5 degrees.
But when it goes from A0 to A-30, it cannot break the angle.

the setting  is :
brk_mv_head  : 1     #Break the 5 axis moves to remove gouge #** 0
brk_max_ang  : 2     #'brk_mv_head' maximum angle move, applied if chordal 5

Tool Length has to be accounted for somewhere. The CAM with the correctly configured post could care less, but for holder avoidance and to use CAM to is true capabilities then taking the time to define all of that there will be the correct process. You never mentioned the control is it a Heidenhain or Siemens?

Hi man

Yes you are right.

My controller is a Heidenhain TNC530.

 
My operation is shown very well in the car simulation. I builded miy machine in Mastercam MachineSim to check better.

Although, I worked with an OSAI PADE 5 Axis Head/Head for several years.

For that machine, I would definitely enter the tool length in the G-code, because of RTCP..

But in table/table Vertical CNC machine, Just face the tool tip on the reference part face, for each tool

Thanks

Hi David

I manually place a Mill-Tool with a tool length of 150mm.

And I entered the value of 150mm in HMI-ToolManager.

Also I am enter The "Tool CALL 0" in G-Codes.
But when running the program, only the Z-Axis changes.
If I change the tool length to 0, Just Z axis move down  150mm.
!
But my main question is: on this type of machines(HT , BC), should the tool height be determined by the HMI or Block of "Tool Def", or not?

Because in my previous machine, which was a (TT , CA), I did not need to enter the height of the Tool for Single-Tool machining. And I just entered the "Tool Call 0" without tool length, And did working fine.

Hello

I am working on a Table Head (XYZ Head=B  Table C) 5axis (DMG - Deckel) VMC Machine. (The picture is attached.
The Machine's forth Axis is C and Fifth Axis is B.
I use one Fixed Tool and Define it by "Tool CALL 0 Z S700"
But in 5 Axis operations. The Tool position is in wrong  place.

My questions:
Can I use Zero tool lenght, for this type of machine? 

If yes, I'll need Define it in "HMI Tool Manager"  or   by "Tool Def " in PostProcessor?
Thanks

Very Nice
Thank you

 

Hi 

I'm looking for a way to change the Images, that describe the Cycles in drill cut parameter window.
Is ther any way to customize or change them.
Thanks for your attention.
