AI Technical Summary
The existing cutting methods for GCr15 bearing steel sleeves have problems such as inconsistent kerf width, numerous end face burrs, and poor cutting stability. Furthermore, the control of the focal point position, chuck speed, and auxiliary gas pressure is not flexible enough, resulting in unstable cutting quality.
The system employs adaptive matching of process parameters, dynamic compensation of focal position, chuck speed linkage control, segmented control of auxiliary gas, and anti-adhesion control at the cutting end to generate an initial narrow-slit pipe cutting parameter combination. The cutting process is then corrected and optimized through cutting quality feedback.
It achieves stable kerf width, improved end face quality, and increased cutting efficiency, while reducing end face burrs and cutting adhesion, thus improving the stability and consistency of the cutting process.
