$pos_act

hi
 MR skyfire

  I am working with a plasma cutting robot
I can use $ pos_act better? to move the base and repeat the cutting area and not have to repeat the programming of the piece to be cut

thanks

It depends on what you want to do.  You can use $POS_ACT and project your hole-cutting geometry out into space.  But to do that, you'll need to have a Base built that matches the orientation of your work piece.

hello all

continuing the theme $ pos_act

I created a base in this case BASE (13)
I have some questions

I move that points to plasma cutting program repeated in a piece that is
  cut several times the same?
main_points () ;this is the points program

they should be with the base (13) ?
and intermediate points with another base nullframe eg base (0)?

example:
DEF cambio_base_1( )

 ;Make your modifications here

  ;ENDFOLD (USER INI)
;ENDFOLD (INI)
BASE_DATA[13] .X= $POS_ACT .X
BASE_DATA[13] .Y= $POS_ACT .Y
BASE_DATA[13] .Z= $POS_ACT .Z
;FOLD WAIT Time= 0.2 sec;%{PE}%R 5.2.271,%MKUKATPBASIS,%CWAIT,%VWAIT,%P 2:0.2
WAIT SEC 0.2
;ENDFOLD

so to move the base to the new cut?


big thanks

Well, it's a start, but your critical issue will be orientation.  If the orientation of BASE[13] doesn't match BASE[0], your cutting pattern will be skewed.

For example:  if you want your cutting pattern to run along one edge of the work piece, your example will only work if that edge is almost perfectly aligned with either the X, Y, or Z axis of BASE[0].  If your work piece is not aligned with the robot's BASE[0], your pattern won't follow that edge.  In the worst case, if your plate is skewed in the wrong direction, your tip could start out at the right height above surface at the beginning of your program, but end up too high, or too low (crashing into the work piece) as you move away from the start point.
