Development of the intelligent cylindrical grinding system considering the thermal deformation of a workpiece

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
In cylindrical grinding, the size accuracy of a workpiece decreases due to the thermal deformation of the ground workpiece. To improve the size accuracy, it is necessary to consider the thermal deformation of the workpiece during grinding process.
