Beschreibung
Zusammenfassung:	The invention relates to a quality determination device and a quality determination method. The quality determination device (10) includes an acquisition unit (34) for acquiring a drive current during tapping, from a motor provided in a machine tool (12) that performs tapping, and a determination unit (36) for determining acceptance or rejection of a screw hole formed by the tapping, based on the drive current, an electric power of the motor (M) obtained from the drive current, or a torque of the motor (M) obtained from the drive current. 本发明涉及优劣判定装置及优劣判定方法。优劣判定装置(10)包括：取得部(34)，其从进行攻丝加工的机床(12)所具备的电机(M)取得攻丝加工中的驱动电流；以及判定部(36)，其基于驱动电流或者根据驱动电流求出的电机(M)的功率或电机(M)的转矩，判定通过攻丝加工形成的螺纹孔的优劣。
