When measuring the workpiece, according to different processing accuracy content and accuracy requirements, users can use differentJob measurementMethod. Today, billion Leride will introduce this to you3Ways to make sure you know what you're doing:

    First, according to whether the measured parameters are directly measured, it can be divided into direct measurement and indirect measurement.
    Direct measurement:Direct measurement of the measured parameters to obtain the measured dimensions, such as calipers, comparators.
    Indirect measurement:Measurement of geometric parameters related to the measured dimensions, calculated to obtain the measured dimensions, such as measurement with a gas momentum meter.
    It can be seen that direct measurement is more intuitive, indirect measurement is more complicated. However, when the size to be measured or the accuracy requirements cannot be reached by direct measurement, indirect measurement has to be used.
    Second, according to whether the reading value of the measuring instrument directly represents the value of the measured size, it can be divided into absolute measurement and relative measurement.
    Absolute measurement:The reading value directly represents the size of the measured dimension, for example, measured with a vernier caliper.
    Relative measurement:The reading value represents only the deviation of the measured dimension from the standard quantity. If you use a comparator to measure the diameter of the shaft, you need to adjust the zero position of the instrument first, and then measure, the measured value is the difference between the diameter of the side axis and the size of the measuring block, which is a relative measurement.
    Under normal circumstances, the relative measurement accuracy is higher, but the measurement is more troublesome, for example, the calibration gauge is required before the measurement of the gas momentum meter.
    According to whether the measured surface is in contact with the measuring head of the measuring instrument, it is divided into contact measurement and non-contact measurement.
    Contact measurement:The measuring head is in contact with the surface to be contacted, and there is a measuring force of mechanical action, such as measuring with a micrometer.
    Non-contact measurement:The measuring head is not in contact with the surface of the measured part, and the non-contact measurement can avoid the impact of the measuring force on the measurement result and avoid the surface damage of the smooth part, such as the measurement by projection method, light wave interference method, and gas momentum meter.
