The advantages and disadvantages of different measurement methods:
The measurement method of any one-key measuring instrument from different starting points, there will be different measurement results, so what are the advantages of this result, and what are the disadvantages? Let's break it down one by one:
Direct measurement and indirect measurement, direct measurement can obtain the direct value of the measurement from the metering appliance, while indirect measurement needs to be measured through function connection in order to reduce errors, direct measurements are generally chosen, and indirect measurements are used only when necessary.
Measurement and indirect measurement, measurement refers to the measurement that the full value of the measurement is read directly from the reading equipment of the metering appliance, while the relative measurement refers to the measurement that the indication value of the metering appliance indicates the error of the measurement and the known standard quantity, and the measurement is the sum of the indication value of the measuring instrument and the standard quantity. In general, the measurement accuracy of the relative measurement is higher than the measurement.
Single measurement and inductive measurement, single measurement is to measure the parameter separation of the measured workpiece, and the inductive measurement of the relevant amount of inductive comments and conclude. For example, after different measuring tools collected data points and product model, the use of SmartProfile summary analysis software to compare the error in the future as a graphical error determination, eliminate the phenomenon brought by a single scale discrimination, more direct, The power of single measurement is lower than that of inductive measurement, but the results of single measurement are convenient for process analysis, especially for the analysis and determination of scale eligibility under the premise of using different benchmark determination.
Touch measurement and non-touch measurement, clear, non-touch-type measurement without touching the product surface, the accuracy of the three-dimensional measuring instrument can be guaranteed, and the power is higher, will not be due to touch the product deformation and scratch. In the industrial high quality control category, the proportion of non-touch measurement is gradually increasing 3D image measurement can also add multiple sensors, which further broadens the measurement and is a sharp tool for induction and comment.
Online measurement and offline measurement, online measurement instrument is implemented in the production site and production process, and the measurement results to control the processing and adjustment of the workpiece, and timely detection of waste, but because it is in the production site the measurement accuracy cannot be very high, Off-line measurement refers to sampling or full inspection of the produced and processed workpieces in the laboratory, so that the accuracy can be fully ensured and the quality can be traced to the source.
Equal and unequal precision measurement of one-key measuring instrument, Equal precision measurement refers to the measurement when all the factors and conditions of the determination of the measurement accuracy are unchanged, and the measurement under the same measurement conditions can't be guaranteed if the accuracy is not equal. Generally, the measurement with equal precision is chosen as far as possible to reduce the influence of human error or uncertain factors on the measurement uncertainly. Follow the development of the industrial output, the artifact is more fine, about how to measure small artifacts, how to quickly improve volume measurement problem about is there is no way to deal with traditional together and one-click meter all able to do it, and god's requirements and professional semi-active and active measuring instrument was developed, one key power also deals with the problem together. This is the new era of new development brough new products. Automatic image measuring instrument when measuring gear is a kind of parts we produce day in common, often seen in the many mechanical equipment, and gear is widely used, along with the economic development of the use of gear also gradually to increase so also increased the requirements on the use of the gear, more strict requirements on the scale of gear. One-click meters are becoming more and more powerful.
