LIB_SPF_Convert_Point

Hi All,

 

I found the LIB_SPF_Convert_Point method in the documentation.

Can anybody tell me what this function does and how to use it?

 

I need to convert the first position of the tool in a titled plane to the main mcs?

Is this function suitable for this?

With LIB_SPF_Convert_Point you can get mom_pos and mom_out_angle_pos with the defined kinematic.

eg

LIB_SPF_Convert_Point real  -- get the values for real kinematic

LIB_SPF_Convert_Point plane  -- get the values for tilted plane kinematic

LIB_SPF_Convert_Point simultanous   --  get the values for TCPM kinematic

LIB_SPF_Convert_Point reload  -- reload the values before you doing any convert

 

Kinematics are defined in the Postconfigurator

 

If you need this for preposition the tool before the first tool path point it is simpler that you use preposition function in PC.

 

Regards

I tried it with the fanuc controller but it didn’t seems to work.

Take the OOTB SIM05 Fanuc example and change settings below.

Then simulate CAVITY_TOP and you will see the problem.

 

Tilting Plane Kinematics Settings --> Prepositioning Plane Operations --> On

Approach Motion --> Splitting for Positioning Operations --> On

 

I want the machine to approach first XY and then Z.

The motion should not be in the tilted plane directions but in the directions of the machine axes.

 

So I started to write my own functions for this but I can't get the coordinates of the first position relative to the main mcs, because the first position is in a tilted plane.

in PB I am using mom_mcs_goto() - it is related to MCS and not tilted coords
