In the last article, Millired talked about it for you3Kind of Job measurementThe methods include direct measurement and indirect measurement, absolute measurement and relative measurement, contact measurement and non-contact measurement. You think that's how you measure a workpiece3What kind of seed? Of course not! Here, Millired will provide you with the rest3Kind of Job measurementMethod.
    First, according to the number of measurement parameters, it is divided into single measurement and comprehensive measurement.
    Individual measurement:Each parameter of the part under test is measured separately.
    Comprehensive measurement:Measure the comprehensive index that reflects the relevant parameters of the part. For example, when using a tool microscope to measure the thread, the actual diameter of the thread, the half Angle error of the tooth profile and the cumulative error of the pitch can be measured respectively.

    Comprehensive measurement is generally more efficient, more reliable to ensure the interchangeability of parts, and is often used for the inspection of finished parts. Single measurement can determine the error of each parameter respectively, which is generally used for process analysis, process inspection and measurement of specified parameters.

    Second, according to the role of measurement in the processing process, it is divided into active measurement and passive measurement.
    Active measurement:The workpiece is measured during the machining process, and the results are directly used to control the machining process of the parts, so as to prevent the production of waste products in time.

    Passive measurement:Measurement of the workpiece after machining. This kind of measurement can only determine whether the workpiece is qualified, only to find and remove the waste.

    Third, according to the state of the measured part in the measurement process, it is divided into static measurement and dynamic measurement.
    Static measurement:Measurement is relatively static, such as a micrometer measurement.

    Dynamic measurement:During the measurement, the measured surface and the measuring head move relative to each other in the simulated working state.

    The dynamic measurement method can reflect the situation of parts close to the use state, which is the development direction of measurement technology.
