SUMMARY

The discussion centers on the operation of Fanuc robots, specifically using RJ 2 and RJ 3 controllers for MIG welding applications. Users often adjust robot positions manually by setting the coordinate system to "Tool" and using low-speed increments, but this method lacks precision. A user inquired about directly specifying movements, such as ".3mm in the positive direction along the Y Axis." A potential solution was found through a patent application for software that could facilitate this precise movement.

PREREQUISITES
  • Understanding of Fanuc RJ 2 and RJ 3 controllers
  • Familiarity with robotic coordinate systems and tool settings
  • Basic knowledge of MIG welding processes
  • Experience with software applications related to robotics
NEXT STEPS
  • Research Fanuc robot programming techniques for precise movements
  • Explore the functionalities of the software mentioned in the patent application
  • Learn about coordinate transformations in robotic systems
  • Investigate user manuals for Fanuc RJ 2 and RJ 3 controllers
USEFUL FOR

Robotics engineers, automation specialists, and technicians working with Fanuc robots, particularly those involved in MIG welding applications and seeking to improve precision in robotic movements.

Has anyone here worked with Fanuc robots? At my shop, we use RJ 2 or 3 controllers on all of our MIG welders. I sometimes have to make small moves in the robot's point positions. This is generally done by putting the robot's coordinate system in "Tool", finding the axis I need, and then setting the speed to 2 or 3 %, and "bumping" the directional button a couple times until the location looks about right. Obviously, this process is not very precise. I'm wondering if there isn't a way to just tell the bot that I need to go ".3mm in the positive direction along the Y Axis"?

I'm looking around online for instructions on Fanc RJ2/3 controllers, but this question is too complex for any of the search engines I use to find an answer on the net. I could look it up in the manual, but that's at the shop and when I'm there I don't have time to read! Any help would be greatly appreciated.

LURCH did you end up figuring this out? The Fanuc Robot looks pretty neat!
 
OK; after some pretty extensive searching, I did find an answder of sorts. Clusty dug up a link to a patent application for a software packet that would do what I want. I guess that settles that!
