研究目的
Investigating the influence of static load on the error correction of multi-axis systems and comparing the volumetric accuracy between loaded and unloaded conditions.
研究成果
The experiment demonstrated significant differences in volumetric accuracy between loaded and unloaded conditions, emphasizing the need for error measurements under load. The 'zero point' migration under load allows for dynamic error correction, improving machine-tool accuracy across a larger workspace.
研究不足
The study focuses on static load influence, potentially overlooking dynamic load effects. The method's effectiveness may vary with different machine types or load distributions.
