Turning tool - direction of machining

Hello ,

it is possible somehow to get direction of turning? (5ax millturn machine)

Look at pciture bellow  how tool (red) engages the part.

I want to output proper O:

Ofcourse I want to avoid UDE.

 

Thank you for tips.

I'm a little confused by your question.

 

By "direction of turning" do you mean spindle direction (M3/4, sometimes M203/4 or M303/4)?

Or tracking point?

or OD/ID/forwards/backwards?

OK sorry.

Just look at the picture.

According where place where is tool/insert do machining - there have to be proper output of G320 O..,

I dont know how make some logic to output these numbers.

It is some tracking point in millplus control.

I've never seen that kind of control, apparently.

There are a few MOM variables you could try to find out which tracking point of the tool was used...

mom_tool_tracking_point 
mom_tool_tracking_type 
mom_tracking_point_adjust_register
mom_tracking_point_cutcom_register
mom_tracking_point_name
mom_tracking_point_p_number
mom_tracking_point_radius_id
mom_tracking_point_type

 

You might also need info on the tool & holder angles (be careful if these are Radians or Degrees!)

mom_tool_holder_angle
mom_tool_holder_angle_for_cutting
mom_tool_orient_angle
mom_tool_orientation

 

If your machine has a B axis (that can rotate the tool), you might also need to check mom_out_angle_pos() (or whatever you use to orient the B axis)

 

Finally, you might need to deal with the cut angle and/or infeed angle (again I think these are radians)

mom_cut_angle
mom_cut_angle_method

mom_infeed_move_angle

 

I'm not saying you need ALL of the above, but you will have to figure out which ones get you the info you need.  I may have also missed some, but hopefully you can find what you need based on above.

 

I suggest creating a test part to test all the possible options / cases out & verify on the machine.

Also remember - NX does NOT clean up after itself, so these variables will likely persist after they are no longer valid.  So be careful!

(I have a proc that I add to the "end of path" event in my post that deletes most of the mom_tool* variables if the next op has a tool change)

thank you for reply,

Millplus is older control, it is dmg version of heidenhain and it is able do turning operation.

 

I use momtoolaxis2 to calculate holder angle = B axis. (It is in custom command in templates for millturns.)

Then I use some variables to get proper tool orientation in the spindle.

 

And I am thinking to use mom_tool_orient to output O parameters (picture)
