【摘要】 驻留时间的求解是计算机控制光学表面成形(CCOS)中最为关键的问题,它直接影响面形的收敛速度和面形精度。提出以面形精度和收敛速度两者加权综合最优的原则,对求解驻留时间的去除系数进行优化,得出其优化式,并对优化式中影响两者权重的系数β进行仿真分析, 结果表明β取值[0．1,0．3]时能使驻留时间达到最优。更多还原

【Abstract】 Gaining dwell-time is the key problem for computer controlled optical surfacing(CCOS). It affects the manufacturing time and the last surface error directly. A rule of minimizing dwell-time and left error is proposed. According to this rule, an optimized expression of removal coefficient is gained. Then the β coefficient of the optimized expression is analyzed and simulated. The analysis results show the most optimized dwell-time could be gained only as β belongs to [0. 1, 0. 3].更多还原
