坐标测量系统(CMSs)的软件补偿由于能以很低的价格,显著地改善系统性能而获得广泛的应用．即使对于已经建立了完善模型方程的坐标测量系统,仍然存在与其相适配的确定模型参数的过程是否最佳的问题．在更差的情况下,模型方程尚未建立,需要从建模到试验的全部实践．文中从补偿过程的角度讨论这一问题,确定了需要遵循的一系列步骤．对于每一步骤,指出了相关的问题,并提出建议．讨论了两种在性质和数学描述上有很大差别的坐标测量系统． Software Compensation for Coordinate Measuring Systems (CMSs) is widely used due to its ability to significantly improve system performance at a fraction of the cost. Even for a coordinate measuring system that has established a perfect model equation, there remains a question of whether the process of determining the model parameters is optimal. In the worst case scenario, the model equations have not been established and require full practice from modeling to testing. The article discusses this issue from the perspective of compensation process and identifies a series of steps that need to be followed. For each step, the relevant issues are identified and recommendations made. Two types of coordinate measuring systems that differ greatly in character and mathematical description are discussed.
