科学技術の発展に伴い、粗さ計の技術と機能は継続的に強化、改良されてきました。粗さ計は、測定精度が高く、安定性が高く、操作が簡単であるため、急速に普及しています。現在では、機械加工・製造、電力、通信、エレクトロニクスなど、粗さ検査を適用する業種が増えており、日常生活で使用する文具、食器、人間の歯の表面などでも表面粗さ検査が必要となっています。 . Roughness meter measurement method When measuring the surface roughness of a workpiece, place the sensor on the measured surface of the workpiece, and the driving mechanism inside the instrument drives the sensor to slide along the measured surface at a constant speed. The sensor senses the roughness of the measured surface through the built-in sharp stylus. The roughness of the measured surface of the workpiece causes the stylus to shift. This displacement causes the inductance of the sensor inductance coil to change, thereby generating an analog signal proportional to the measured surface roughness at the output end of the phase-sensitive rectifier. This signal passes through After amplification and level conversion, it enters the data acquisition system. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are read out on the LCD, can also be output on a printer, and can also communicate with a PC.
With the development of science and technology, the technology and functions of roughness meters have been continuously strengthened and improved. The advantages of roughness meters such as high measurement accuracy, good stability, and easy operation have rapidly become popular. Nowadays, more and more industries apply roughness testing, such as mechanical processing and manufacturing, electric power, communications, electronics, etc., and even the stationery, tableware, and human tooth surfaces used in people’s daily lives need to be tested for surface roughness.
