CNC sawing machines have gradually replaced metal semi-automatic band saws and circular sawing machines, becoming the mainstream cutting machine on the market. People are getting higher and higher requirements, and in terms of functions, they are demanding more and more. As the first process of mechanical manufacturing, CNC sawing machines have higher and higher requirements on the precision and speed of cutting materials for band saws. It is in this market environment that the Xiangrui CNC Sawing Machine R&D Center cooperates with a well-known measurement and research company in China. After a year of research and development, the advanced measuring system of metal band sawing machine - the capacitive measuring system was jointly developed. The characteristic is that the sensor of the capacitance measuring system adopts an equal-pitch gate structure, so that the measurement accuracy is not directly related to the length, so it is very suitable for large displacement measurement. The measurement speed is fast. The sensor has a simple structure and is easy to be integrated with an integrated circuit, making it easy to mechanically design. The requirements for the use environment are not high. It can resist the interference of electricity and magnetic field; after adopting appropriate protective measures, it can prevent oil, dust and is not sensitive to air humidity, and is suitable for use in the production site of CNC sawing machine workshop. Low energy consumption, many functions, and easy to use. The circuit of the capacitance measuring system has zero point at any point, metric conversion, value retention, maximum value minimum value search, value pre-value, measurement speed too fast and electromagnetic voltage low alarm function, which makes the measurement system easy to use and ensure The sawing machine measures the correctness of the data. Serial code data output, for the computer to perform the required processing and printer data recording. This provides a convenient condition for product quality control.


measuring system


      A measurement system is a collection of instruments or gauges, standards, operations, methods, fixtures, software, people, environments, and assumptions used to quantitatively or qualitatively evaluate a characteristic being measured; the entire process used to obtain measurement results. In CNC sawing machines, the accuracy of the measuring system directly affects the dimensional accuracy of the machined part.


      The ideal measurement system should only produce "correct" measurements for each use. Each measurement should always match a standard value. A measurement system that produces an ideal measurement should have zero variance, zero bias, and any statistical property of the product that is misclassified to zero probability.


Measurement System Analysis Considerations


      Whether the gages and test equipment can be used correctly determines the accuracy of the SPC data to a large extent. In order to ensure the correctness of the results and the optimization of the overall system performance, the equipment needs to be evaluated. Of course, equipment evaluation is not just in the lab, but also in the production environment. So how do you do a good job of measuring system analysis?


      1. Stand-alone database - fully ODBC-compliant and runs under any ODBC database.


      2. Easy data entry interface - easy for operators to use and learn.


      3. Multiple gauges, features, and calculations—work multiple studies in one analysis and produce broader and meaningful results.


      4. Diversification Reporting and Control Chart Analysis – Provides five separate reports and control chart analysis for each gage study and can tailor reports for different management levels.
