精密加工中人机工程信息测试研究

Research on the Testing of Human-Machine Engineering Information in Precision Machining

应用传感器系统,对精密加工中的切削力、转矩、手轮的平均转速、重心移动轨迹长、作业时间以及作业误差等操作信息和主观疲劳和客观疲劳等疲劳信息进行了测定.通过对检测数据的分析,得出了在精密加工中与操作疲劳和生产效率有关的操作信息.依据分析结论,应对操作者进行有针对性的操作培训,并对加工环境进行改善,以缓解操作者的疲劳.

Aimed at improving the productivity and quality of enterprise ,the sensor measurement system was used to test the operational information such as cutting force, torque, the average rotation speed of hand wheel, length locus of gravity center, task time and task error, and fatigue information such as subjective and objective fatigue in the precision machining. The main factors relating to operator＇s fatigue and working efficiency were inferred by the testing result and quantitative analysis. Based on the analysis conclusion, the corresponding operation training should be carried on to the operators, and the processing environment should be improved to alleviate operator＇s weariness.
