This research is primarily aimed, in order to generate mirror surfaces, a personal computer control prototype ultra-high precision lathe has actually been built. Further, the equation of whether the said cutting theory derived from dislocation theory capable of explaining the ultrahigh precision cutting mechanism, observed in experiments employing the PC control ultra-high precision lathe was also studied. (1) The ultra-high precision machined surface roughness achieved with aluminium was Rmax= 0.01μm in PC control system. And also, the flatness is 0.1μm/φ 50 mm. (2) The shearing stress computed based on dislocation theory closely coincides with that obtained from macroscopic machining experiments. (3) A PC controlled ultrahigh precision lathe capable of the results in (1) through (2) above has successfully been constructed on an experimental basis.
