G101076 振動モードを利用したFPD用ガラスの非接触割断加工([G101-07]機械力学・計測制御部門,一般セッション(7))

In recent years,the demand of the glass for FPD has been increasing.Therefore,the development of new cutting technology with higher manufacturing efficiency is desired.Usually,there are two processes in cutting the FPD glass.The first process is to scribe on the glass by laser or wheel cutter.Next process is to cut the glass along the scribe line by bending stress.In this process,the glass is cut using the way that runs along the scribe line while pressing by the rubber roller.If you want to cut the direction orthogonal to the two,you must repeat the same process after the glass is rotated by 90 degrees.If this process of rotation can be eliminated,it will be possible to shorten the processing time.Therefore,using the tensile stress generated by the loop of the vibration mode,we hypothesized that glass could be cross-cut at once.As a result,it is possible to cross-cut by using the sound waves superposed two resonance frequencies.By using this method,it will be possible to cut the glass in non-contact.
