The root technology which means production-based technology, Welding, molds, Plastic working, Surface treatment, Heat treatment, Casting is required for public service by platform system. Platform system is made up web portal system and register knowledge system and the database which is built by register knowledge system is serviced through web portal. The platform system is primarily intended for enterprises that are operating and easier for companies to develop the skills to be performed may be helpful. Unilaterally from information providers to the technical information that is provided along with the ability to efficiently implement improvements, and further improved by establishing a broader information system platform can be expected.

Burr is occurred in mechanical machining process, it is unnecessary creation for highly precision machining. For this reason, deburring process is positively necessary. Especially, micro burr of under several micro meters is difficult to remove through macro deburring process. To micro deburring, we carried out a experimental deburring works using micro abrasive blaster. A micro abrasive was used a polymer media less hardness than WA(Al₂O₃) for only burr removal effect except edge of cutting profile. For experimental variable of micro blasting process was selected jet pressure, scan speed and scan times.
