| Summary: | 碩士 === 國立臺灣大學 === 機械工程研究所 === 81 === A thermal model in wet grinding process is presented. The
thermal effect of shear zone is taken into account. By taking
all the parmaters needed in the model from the experimental
result, the temperature of the workpiece surface in the
grinding zone can be predicted. Experiments show that the flow
rate of coolant under general grinding condition is sufficient
to cover the coolant thermal boundary layer in the grinding
zone. The predicted workpiece surface temperature has been
compared to experimental data on some grinding conditions. A
good agreement is obtained expcept for creep feed grinding
process when water-based coolant is used. The difference
between the theoretical values and experimental results are
attributed to constant thermal properties , and negligence of
transverse conduction in the development of thermal model.
