What is the function of the feed hold button on a CNC lathe?

[Jack8rkin]

Hello everyone!

We are translating a manual for a CNC lathe and need help with one unclear phrase.
Here is the phrase:

"CYCLE STOP

This is the feedstop buton. Once activated, it moves axes in hold and interrupts program execution."

Could anyone explain what this button does exactly?
Does it just stop the feed along the axes or really moves something like a tool aside (to a certain point)?

Thank you

It stops the spindle from moving and pauses the program, but does NOT affect the rpm of the spindle. Here's a reference, look at page 39.

Edit: That's for a CNC milling machine, for lathe it would stop the tool post from moving. Not recommended to use during a cut for either machine.
