三坐标在曲线测量方面有着较大的优势,其测量的精确度与测量环境、仪器的精度、参数的选择以及测量方法都有关。在此我们针对以上几个方面分别做一探讨。1 测量环境1.1减少振动的影响一般来说,三坐标测量机在安装时都挖好了防震沟,但三坐标测量机在测量高精度曲线时仍需避开有较大震动的工作时段和环境,以避免零件的移动给测 Coordinate has a great advantage in curve measurement. The accuracy of the measurement is related to the measurement environment, the accuracy of the instrument, the choice of parameters and the measurement method. Here we make a discussion for each of the above aspects. 1 Measurement Environment 1.1 Reduce the Effect of Vibration Generally speaking, CMM dug the shockproof ditch during installation, but the CMM still needs to avoid the working period and environment with large vibration when measuring the high-precision curve , To avoid the movement of parts to the test
