Hi all,
I have to deburr a workpiece with variable dimensions. The Process is working but results are not 100%. The Robot makes alle the correct movements but it´s just deburring half of the part on each side, because it´s moving in a slight angle compared to the external tool, no matter what angle i set up the external tool system with. I´ve set up the tool1 again and tried to tune everything to it´s best, but i´m at my limit now.
The part of the program i´m talking about:
$ACC.CP=10
$VEL.CP= Geschwindigkeit_Gerade1+Korrektur_Geschw_Gerade1
LIN p0
LIN p1
$VEL.CP= Geschwindigkeit_Radius1+Korrektur_Geschw_Radius1
CIRC p2_HP,p2
$VEL.CP= Geschwindigkeit_Gerade1+Korrektur_Geschw_Gerade1
LIN p3
$VEL.CP= Geschwindigkeit_Radius1+Korrektur_Geschw_Radius1
CIRC p4_HP,p4
$VEL.CP= Geschwindigkeit_Gerade1+Korrektur_Geschw_Gerade1
LIN p5
$VEL.CP= Geschwindigkeit_Radius1+Korrektur_Geschw_Radius1
CIRC p6_HP,p6
$VEL.CP= Geschwindigkeit_Gerade1+Korrektur_Geschw_Gerade1
LIN p7
$VEL.CP= Geschwindigkeit_Radius1+Korrektur_Geschw_Radius1
CIRC p8_HP,p8
$VEL.CP= Geschwindigkeit_Gerade1+Korrektur_Geschw_Gerade1
LIN p9
LIN p10Tool and Base are set by an inline formular movement to a pre position at the beginning. Base is set to external tool 12, tool is set to tool1.
The single positions are calculated by the dimensions from the workpiece:

I tried adjusting the external tool angle but that didnt give me any results.
I would be happy to hear suggestions,
thanks and have a great day!
