Discussion Overview

The discussion centers around the function of the feed hold button on a CNC lathe, specifically its role in program execution and axis movement. Participants seek clarification on whether the button merely stops the feed or if it also affects the positioning of the tool.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks for clarification on the function of the feed hold button, questioning whether it simply stops the feed or moves the tool aside.
  • Another participant states that the button stops the spindle from moving and pauses the program, but does not affect the spindle's RPM. They provide a reference to a book for further information.
  • The same participant notes that while the reference is for a CNC milling machine, for a lathe, it would stop the tool post from moving and advises against using it during a cut.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the exact function of the feed hold button, with differing interpretations of its effects on the tool and program execution.

Contextual Notes

There are unresolved assumptions regarding the specific behavior of the feed hold button across different CNC machines, as well as the implications of using it during a cut.

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
