Development of Grinding Temperature Measuring System Considering Compensation of Thermocouple Dynamic Responding Error

摘要

In order to improve grinding temperature measuring precision the compensation method of thermocouple dynamic response errors and the modification method of non-linearity of thermocouple characteristic curve were analyzed and then programmed with VC++ language. Further more a grinding temperature measuring system was developed by means of second development of 10612CF type of TOP DAC (data acquiring card) with LabWindows/CVI, which provides three kinds of estimating thermocouple time constant methods. Primary debugging results showed that the measuring system developed is simply easy to handle and can satisfy experimental study of grinding temperature.
