Recently, the trends of industrial products move towards more miniaturization, varietyand mass production. Micro drilling which take high precision in cutting work is required toperform more micro hole and high speed working. Especially, Micro deep hole drilling is becomingmore important in a wide spectrum of precision production industries, ranging from the productionof automotive fuel injection nozzle, watch and camera parts, medical needles, and thick multilayeredPrinted Circuit Boards(PCB) that are demanded for very high density electric circuitry. Theindustries of precision production require smaller holes, high aspect ratio and high speed workingfor micro deep hole drilling. However the undesirable characteristics of micro drilling is the smallsignal to noise ratios, wandering motion of drill, high aspect ratio and the increase of cutting forceas cutting depth increases. In order to optimize cutting conditions, an experimental study on thecharacteristics of micro deep hole machining processes using a tool dynamometer was carried out.And additionally, microscope with built-in an inspection monitor showed the relationship betweenburr in workpieces and chip form of micro drill machining
