Hi,
My first post, hope I can contribute something back to the forum in the future.
I have a part on the machine that has an M36 x 4 thread on the end.
I'm using the tailstock but I'm short of space to get the tool up to speed.
I seem to remember that the manuals gave a formula for calculating how much distance in Z was required for the threading tool to get up to speed but I can't find it anywhere.
I've only got about 6mm clearance so I'm running slow which is giving a rough thread.
I realise that this formula is going to vary depending on how fast the machine can accelerate.
The machine is a Mori SL25 with a fanuc 16T control (mid 90's).
Just hoping to get a ballpark figure as I can't afford for the thread to be out of pitch.
