Question: How does everyone find their Zero Position on their robots?
(95% of our cells are welding cells)
Current Method: We use a point to point method where there is a fixed pointer inside the cell and we add a pointer to the end of the torch. We use three different programs to help figure out the zero for all the axes.
-Bracket program where we make points (indents with a punch) on the robot and used the fixed pointer that "touch" the points on the robot. Each point corresponds to a 2 or 3 axis.
-TCP program that aligns the pointers perfectly to each other (linear vertical) where the tips are barley touching one another. We use this to see what axis needs to be brought in and use the difference in degrees to adjust our zero points
-Zero program is made when the cells come in and we use the witness marks on them to create the original zero point.
Comments: I'm not a fan of this method due to whenever a robot gets remastered we have to go through every program and make adjustments. 8 out 10 times its way off and everything needs touched up which causes quality issues and production interruptions. I'm also not a fan of the bracket program because each point (indent) relates to more than one joint.
First post, if anything needs more explaining I will explain better.
