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

AI Thread Summary
The feed hold button on a CNC lathe, also referred to as the cycle stop button, pauses program execution and stops the movement of the axes, but does not affect the spindle's RPM. It does not move the tool aside to a specific point; rather, it simply halts operations. While it can be used to interrupt a cycle, it is not advisable to activate it during a cutting operation. This functionality is crucial for ensuring safety and precision during machining tasks. Understanding its operation is essential for effective CNC lathe management.

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.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter.
