HI ED Danzer,
Will the manufacturers do the stiffness test on their own and give us the results.
Cousl you explain the stiffness test, how should it be performed?
But it doesn't seem practical to do a rigidity test. If manufacturers dont allow this test, how will we be able to perform this test. we cant buy different robots, from different manufacturers and do this test on them.
Hi Ed Danzer,
The problem was resolved by doing the following,
1. changing the PID values for robot axis servo.
2. Changing the speeds as we approach the corners and move out from the corner.
3. The tool angle and orientation is changed outside the material and then the drill bit is moved...
We had tried reducing the cutter diameter and the feed rate and even that didnt help.
It was like the robot did a jerk as it started the move and when ever it changed direction.
Thats why I reduced the speed of the robot movement to say 5mm/s , for first 5mm of the distance and then ramped the...
HI TygerDawg,
The robot that was used previously was IRB2400 robot from ABB. it could take a payload of 16 kilos and we had a spindle at the ned of the robot which weighs about 7kg. The speed it was run at was based on the chip load and the speed was kept at 40mm/s max. The way i got around...
Hi Every one,
I have an machining operation where a robot has to machine holes in abs plastic and machine square holes to accurate measurements say for instance machining the keyboard pockets in Atm machine front fascia. I have faced problems earlier with ABB robots where in the robots shows...
