What is the longest single cycle time you ever in your life time? What's it for if you don't mind?

My longest cycle time was on my toyoda fh45 at my last job.I ran parts for Alcoa csi.I had 34 tools and a cycle time of 1hr 24mins.At the same time i ran some sprockets for rexnord with a cycletime of 58mins.Made for a boring but fun day.Alot of reading and watching tv!

2hours and 5 minutes as I recall, roughing out this large chunk of alum, I will try and get a pic up of it. prototype part that was going to be cast.

Longest total cycle time..... 72 hours.... (11k lbs steel weldment)

Longest single operation cycle time... 23 hours 40 min (aluminum high vacuum chamber)

I've done some others in the past that may have even been a little longer.... this is just in recent memory....

A few days of lights out machining, including time to replace 2 spindles. It was a mold core.

Nowadays I make a lot of electronics/microwave housings from Alum, and cycle times typically run between 20 to 400 minutes.

Just over 17 hours for me - it was an engraving job on a large aluminum panel. The job ran overnight unattended.
