Recently, the deburring process which is last process of manufacture is one of the important process for complete product. The development of shape guided automatic deburring machine is essential because manual deburring process has very irregular quality and higher error rate as well as consider irregular shape radius. In order to develop of shape guided automatic deburring machine, in this study, we conducted 3D design, assembly, machine simulation and structural analysis using CATIA. Also, we conducted to make automatic deburring machine and conducted a performance test.

In process of the finish face milling of the hardended STD11 steel(H /sab r/ c50,55) by CBN tool, the optimum tool shape is suggested,which can minimize the tool fracture and by chipping by impact. The obtained results are as follows. (1) The optimal chamfer angel was about 25 .deg. , and the suitable chamfer width was 0.2mm. (2) The nose radius of tool was most excellent at 1.2mm in the viewpoint of tool wear and surface roughness. (3) Wear speed was effected by sintering method of CBN tool B.U.E

The purpose of this investigation is experimentally to clarify the machinability and optimum tool geometry on milling of hardened STD11 steel. In the finish process office milling of high hardened STD11 steel by CBN tool, the optimum tool shape is suggested, which can minimize the tool fracture and chipping by impact. It is measured that cutting farce, tool wear and surface roughness generated during single-insert face milling using various geometric CBN tools. It has been found that the optimal chamfer angle of CBN tool is about -$25^{\circ}C$ and the suitable chandler width is 0.2mm. The nose radius of tool is the most excellent at 1.2mm in the viewpoint of tool wear and surface roughness.
