Thermal correction of measuring scale used in coordinate measuring system, involves calculating temperature gradient, based on temperature measured at different points on scale |
摘要 |
The temperature at different points on the scale is detected using temperature sensors (2-4). The thermal correction factor of scale is calculated, based on the coefficient of thermal expansion of scale and the temperature gradient that is calculated from sensor output.
