      다국어 초록 (Multilingual Abstract)

      In this study, the static and dynamic commponents of cutting resistance were measured with tool dynamometer (Swiss, piezo-electric type) when S 45 C, Al-alloy and brass were drilled under the some variable conditions.
      1) The dynamic components of these cutting resistance are not related to the depth of drilled hole.
      2) The static and dynamic components of cutting resistance are increased in accordance with the increase of feed and drill diameter.
      3) The dynamic components of thrust force are increased in accordance with the increase of spindle speed.
      4) The rate of the dynamic component to the static component is 0.3∼0.5 in torque, 0.1∼0.2 in thrust force.
      5) The characteristic of the tool system is affected in dynamic component of cutting resistance, and the created frequency and amplitude of the chip are determined by the drilled materials.
      6) The maximum amplitude of the dynamic component is increased proportionally in accordance with the feed rate and the spindle speed.
