Applicability of “soft-machining” method for drilling fine holes on CFRP and acrylic sheets were experimentally examined. The “soft-machining” is a high-precision machining method for CFRP developed by authors. In the soft-machining, a constant load P applied on the cutting tool becomes the driving force to feed the cutting edge. The drilling of CFRP showed that the applying load P has a strong relation with the maximum cutting force and cutting damage generation. If the applying load P was less than 53N, there was no apparent cutting damage on the drilling surface. In addition, the soft-machining can extend the service life of drill even in the high-speed steel drill. The drilling of acrylic sheet by soft-machining showed a good performance, no sudden temperature rising and cutting resistance fluctuation, during the machining,
