Thermal correction of measuring scale used in coordinate measuring system, involves calculating temperature gradient, based on temperature measured at different points on scale
Thermal correction of measuring scale used in coordinate measuring system, involves calculating temperature gradient, based on temperature measured at different points on scale
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.
