Rotate PH20 Head to New Angles

From ArcoWiki
Jump to: navigation, search

To Rotate the PH20 Head to a new Position there are two methods:

  • By ARCO user interface
  • By DMIS command


ARCO User Interface

  • Set the CMM to CNC Mode
  • Make sure the CAD Window is selected
  • Open the Menu
   CMM -> Make GOTO PH20 2.png or PH20 3.png 
  • Check the label for A and B angle in the PH20 Frame PH20 1.png
  • Fill the text box with the angles to be reached by the head
  • Click the button
  Make GOTO

PLEASE BE AWARE THAT THE CMM WILL PERFORM A 5 AXIS MOVE!
Consider the space around the head in order to avoid collision.


DMIS Command

With CMM in CNC Mode use one of the following DMIS Statement

  • GOTO/HEADCS,AngB, AngA
    Where
     AngB: Angle B that the head will reach
     AngA: Angle A that the head will reach
  
  Example:
  GOTO/HEADCS, 0.0, 0.0
  • GOTO/VEC,i,j,k
    Where
     i: is the I component of the direction of the head after the rotation
     j: is the J component of the direction of the head after the rotation
     k: is the K component of the direction of the head after the rotation
 
Example:
  GOTO/VEC, 1.0, 0.0, 0.0
  • GOTO/PCS,rZ,rY,rZ
    Where
     rZ,rY,RZ are the DMIS Euler Transformation of the current reference system in order to have the Z axis pointing along the desired direction for the head.
 
Example:
  GOTO/PCS,0.0000,90.0000,0.0000
