With the continuous improvement of technology, inspection tools have gradually developed from traditional inspection tools to the emergence of flexible inspection tools. Both have the same function, but flexible inspection tools are more economical to use than traditional inspection tools. With long-term development, can flexible inspection tools completely replace traditional inspection tools? Traditional inspection tools are suitable for mass-produced products, such as auto parts, to replace measuring tools such as card gauges, plug gauges, and coordinate measuring machines. They are usually not reusable. Flexible test fixtures are almost all reusable through adjustment and re-calibration. By comparison, the economics of flexible test fixtures are obvious. From the trend point of view, the automation of error detection and the reusability of the system are the development direction of the inspection tool. What are the specific differences between flexible inspection tools and traditional inspection tools? 1. Flexible inspection tools have some special advantages that traditional inspection tools do not, mainly including: a flexible inspection tool can measure different products with a little adjustment (one-to-many or adjustable, saving storage space, parts can be reused), Automatic measurement, automatic data recording, high measurement accuracy, no fear of deformation (low maintenance cost), short development cycle, etc. Second, the accuracy of the flexible inspection tool is guaranteed by the accuracy of the probe. Because the probe can be reset to zero, even if the tooling accuracy is low or deformed, as long as the probe is reset to zero, the system can automatically complete the compensation, which will basically not affect the use. Although flexibility has the above two advantages, flexible inspection tools also have certain disadvantages. The flexible inspection tool adopts the measuring head method to measure the error, so the measurement points are discrete; while the traditional inspection tool uses the reference profile as the measurement reference, and the measurement points are continuous. Flexible test fixtures are automatic measurements and require a stable power supply; traditional test fixtures are usually purely mechanical measurements and generally do not require a power supply. In summary, although the flexible inspection tool is relatively economical, the flexible inspection tool is an important supplement to the unified inspection tool. In some occasions, such as when the space is not easy to install the probe, only the traditional inspection tool can be used. Flexible inspection tools can not completely replace traditional inspection tools.
