The invention relates to a processing program analyzing device, a processing program analyzing program and a processing program analyzing method. Provided are the processing program analyzing device,the processing program analyzing program and the processing program analyzing method used for carrying out analyses by directly acquiring useful information from a processing program. The device is equipped with a physical quantity calculation part (43) and a physical quantity classification part (45). The physical quantity calculation part utilizes position coordinates of one or multiple commandpoints as for all command points of command point ranges forming the processing program. The physical quantity classification part is used for making a clustering analysis of physical quantities of all command points in order to classify physical quantities into multiple groups.
