| Popis: | The measurement of three-component micro cutting force is perceived as a core requirement for the field of micro machining. However, the existing three-component force sensors cannot meet the requirement because of its excessive range, low accuracy, complex structure, serious coupling and impure extraction of the micro force to be measured. In this paper, a three-component micro force sensor is proposed to measure the three-component micro force simultaneously. The innovative design of combined composition, series connection, coordinate relationship and coil structure make it stand out from the crowd. Mechanical calculation are conducted to solve the stress and strain parameters of designed sensor, which is in turn, be verified by finite element simulation. Finally, the characteristic experiment and uncertainty evaluation of the designed sensor is performed. The results reveal that the relative uncertainty of the three-component force sensor is less than ±0.5‰. Thus, it is thought that the designed sensor can be accurately used in industry. |
