It is desirable that an appropriate machine tool having functions desired by a user can be searched for easily. A machine tool search device includes: a collecting unit that collects information on functions included in each of a plurality of machine tools; an acquisition unit that acquires evaluation points of the functions; an extraction unit that extracts machine tools having a combination of the functions for satisfying search conditions when the search conditions are designated; a calculation unit that calculates an overall evaluation point on the basis of a sum of the evaluation points of the combination of functions and the evaluation points of functions other than the combination, included in each of the machine tools extracted by the extraction unit; and a determining unit that determines machine tools to be recommended for the search conditions on the basis of the overall evaluation point.

A food processing machine includes a plurality of tool parts which are exchangeable and which each comprise at least one electronic data storage in which a tool identification is stored for identifying the respective tool parts, and a controlling system for reading the tool identifications. The controlling system is configured to determine, based on the tool identification read by it from the at least one data storage of an exchangeable tool part installed at the food processing machine, processes basically implementable with this tool part which are possible for an operation of the tool part, and to determine an intersection of detailed processes by a comparison of these processes with processes basically performable by the food processing machine based on machine equipment employed for the tool part and firmly installed in the food processing machine, by which the tool part can be controlled by the machine equipment provided for it.
