Development of Amendable Machining System and Evaluation of its Performance

Nowadays the machine tools have become multi-functional with the development in their speed and accuracy, for example, machining center can be used for grinding. Meanwhile, the deviation-detecting type on-the-machine measuring method has been developed for measuring the machined error of a workpiece on the machine efficiently and precisely. Therefore, it is possible to do roughing, measuring and finishing on a machine without replacing the workpiece. An amending machining system has been studied, in which the machining error of rough grinding is measured by on-the-machine measuring and then dimensional and profile errors are amended by changing the program of finish grinding.
