Abstract: Disclosed is a method for machining a component including: a first processing step of machining a workpiece material into a workpiece in which a needed portion is connected to an unneeded portion via a connecting portion by action of a tool supported by a tool supporting portion on the workpiece material supported by a workpiece material supporting portion in a processing space covered with a cover member; and a second processing step of cutting the connecting portion to separate the needed portion from the unneeded portion by using the tool supported by the tool supporting portion in a state in which a door that divides the processing space is opened for a workpiece material transport mechanism to move into the processing space and at least the needed portion of the workpiece obtained through machining in the first processing step is supported by the workpiece material transport mechanism.

Abstract: A method for producing a cellulose nanofiber capsule according to the present invention includes forming a Pickering emulsion by irradiating a mixture containing cellulose nanofibers, water, and fluid carbon dioxide with ultrasonic waves in a closed container; and facilitating encapsulation using cellulose nanofibers from the Pickering emulsion by opening the closed container. The present invention enables encapsulation using the cellulose nanofibers from a Pickering emulsion that does not contain an organic solvent, for example, and is useful in the technical fields of pharmaceutical agents, foods, and cosmetics, for example.
