An information processing device includes: a mesh setting unit that sets a plurality of mesh zones in a captured image including a scattering range of a substance scattered during machining by a machine tool; an accepting unit that accepts a selection of one or more mesh zones corresponding to an area for removing the substance from the plurality of mesh zones; a substance recognition unit that recognizes a substance state in the mesh zones corresponding to the area with respect to the captured image; and a display instruction unit that instructs display of indicators based on the substance state recognized in the area in time series.

A technique for preventing a coolant from adhering to a discharge inhibited portion is provided. A machine tool capable of machining a workpiece includes: a first discharge unit that discharges the coolant removing a chip of the workpiece; a portion inside the machine tool and to which the coolant should not be discharged; a first drive unit that changes a relative position between the first discharge unit and the portion; and a control unit that controls the machine tool. The control unit performs processing for recognizing a position in the machine tool of a moving object by the first drive unit between the first discharge unit and the portion, and processing for controlling the discharge of the coolant by the first discharge unit such that the coolant is not discharged to the portion based on the position recognized in the recognition processing.

A pneumatic system that eliminates stops due to dirt in the lasers of an Autonomous Drilling Machine uses the resources of the equipment (Compressed Air) to maintain a positive pressure inside the metal protectors of the lasers, thus preventing the entry of dust in suspension and keeping the lasers clean. This avoids unduly stops of the machine due to dust contamination. The system uses a pneumatic control board connected through a flexible line to the machine's compressor's manifold, a frame, a pressure regulator, and a filter. The protectors for the lasers have perforations that allow the installation of diffusors. The diffusors are installed in the protectors to allow entrance of contamination-free compressed air. A flexible line, with its fittings and couplings, connects the pneumatic control board to each of the diffusors.

A machine tool has a cover that prevents chips generated by machining and cutting fluid from scattering around and a plurality of movable nozzles with liquid discharge directions thereof being movable so as to wash out chips that have adhered to or accumulated on an inner surface of the cover. The machine tool is capable of changing a discharge direction of each of the movable nozzles individually. The machine tool compares the state of the inside of the cover before start of machining with the state of the inside of the cover after chips are generated to determine an adhesion or accumulation state of chips. The machine tool thus calculates the liquid discharge direction to wash out chips from the movable nozzles based on a result of the determination.

An assembly for controlling waste material during a hybrid subtractive and additive manufacturing process is disclosed, including a machining tool held in a holder, a shroud disposed around the machining tool, and one or more ports configured to create a negative pressure within the shroud. A method of constraining waste material during a hybrid subtractive and additive manufacturing process of a part includes adding an amount of material to a part being additively manufactured, transforming the amount of material that was added, manipulating a tool to machine a portion of the part being additively manufactured and generating a waste material, sealing a portion of the tool and covering a portion of the part with a shroud, and applying a negative pressure to create an airflow to prevent the waste material from exiting the shroud.
