Abstract
A turning thread automatic diagnosing method includes collecting a spindle actual speed and a feeding shaft actual speed of a lathe; based upon the spindle actual speed and the feeding shaft actual speed, continuously calculating thread errors to obtain a thread error curve; and analyzing an error cause according to the thread error curve. In addition, a turning thread automatic diagnosing system is disclosed, using the method. A data processing system and a storage medium are also disclosed. The technology of the embodiments can automatically identify the problem causing a thread error and provide a corresponding solution.
Claims17
An automatic diagnosis method for thread turning, comprising:
- acquiring a main shaft actual speed and a feed shaft actual speed of a lathe;
- continuously computing a thread error based upon the main shaft actual speed and the feed shaft actual speed, to obtain a thread error curve;
- and
- analyzing an error cause according to the thread error curve.
An automatic diagnosis system for thread turning, comprising:
- a data acquisition unit, a main shaft actual speed and a feed shaft actual speed of a lathe;
- a data processing unit, to continuously compute a thread error based upon the main shaft actual speed and the feed shaft actual speed from the data acquisition unit, to obtain a thread error curve;
- and
