Laser interferometry is commonly used to measure machine axis accuracy but has one major flaw in that it cannot be used to monitor axis dynamic performance while the machine is cutting. Laser measurements are typically made in static mode in fixed positions along the machine axis meaning the axis is stationary when each measurement is made so potentially it doesn't reflect the performance of the machine when it's in its working condition cutting components. This low cost in-situ laser monitoring system will measure axis position, velocity, acceleration and angle at all times even when the machine is cutting ensuring the most accurate method for determining the performance of the machine axis. This data will form the basis of more accurate compensations and/or allow an accurate performance/condition monitoring system. Data from the system can be monitored over time to provide machine degradation information and performance data for monitoring of production.

激光干涉测量是一种常用的测量机床轴线精度的方法，但它存在一个主要缺陷，即不能监测机床切割过程中轴线的动态性能。激光测量通常是在静态模式下沿着机器轴的固定位置进行的，这意味着每次测量时轴是静止的，因此它可能不能反映机器在切割部件时的工作状态的性能。这种低成本的原位激光监测系统将测量轴的位置，速度，加速度和角度在任何时候，即使在机器切割确保最准确的方法来确定机器轴的性能。这些数据将构成更准确的补偿和/或允许准确的性能/状态监测系统的基础。系统的数据可以随着时间的推移进行监控，以提供机器退化信息和生产监控的性能数据。
