Speed of Bar on Roller table after cutting

Click For Summary
SUMMARY

The discussion centers on the speed transition of a bar on a roller table after cutting, specifically comparing the speeds of the rolling mill and the roller table. The rolling mill operates at 10 meters per second, while the roller table runs at 20 meters per second. The time it takes for the bar to accelerate to the roller table's speed depends on friction factors. A rigid connection, such as a rack and pinion, would result in a jam rather than a smooth transition.

PREREQUISITES
  • Understanding of rolling mill operations
  • Knowledge of roller table mechanics
  • Friction dynamics in mechanical systems
  • Basic principles of speed and acceleration
NEXT STEPS
  • Research the effects of friction on speed transitions in mechanical systems
  • Explore the mechanics of rack and pinion systems
  • Learn about the design considerations for roller tables in manufacturing
  • Investigate methods to optimize speed transitions in rolling mills
USEFUL FOR

Manufacturing engineers, mechanical engineers, and anyone involved in optimizing rolling mill and roller table operations.

If rolling mill is running at 10 meters per second and roller table is running at 20 meters per second.
Before cutting of bar, it will move at 10 meters per second.
After cutting bar has to move with the speed of 20 meters per second on roller table.
How much time bar will take to reach to that speed?

It depends on the friction, surely. If it were a 'rack and pinion' / rigid connection, it would jam.
