In one respect, the invention is a coring machine for removing portions of food item blanks, the coring machine including a plate assembly for holding the food item blanks and a pair of coring assemblies, each having a plurality of coring bits that are aligned with passages in the plate assembly.

A drilling system includes a single robotic drilling unit having a drill end effector positioned inside a barrel section configured as a composite sandwich structure having an inner face sheet. The robotic drilling unit is operable to drill a plurality of perforations into the inner face sheet using the drill end effector. The robotic drilling unit is configured to index a hole pattern of the perforations to one or more cell walls of a honeycomb core of the composite sandwich structure. The robotic drilling unit is configured to form the hole pattern in the inner face sheet such that the perforations are located at a spaced distance from the cell walls of the honeycomb core.

The invention relates to a device (1) for drilling holes in the axial and radial direction of a blade root of a wind turbine, wherein the device comprises: a first base (2), which is to be stationary positioned on the ground; a second base (3), which is moveably mounted to the first base (2) and movable along a first direction; first drive means for positioning the second base (3) along the first direction; a rotary arm (4), which is pivotally mounted to the second base (3) around a main axis (5); second drive means for rotating the rotary arm (4) around the main axis (5); wherein the rotary arm (4) comprises a guide track (7) which extends from a first outer end to a second outer end of the rotary arm (4) thereby passing the main axis (5); first drilling means (8) moveably arranged on the guide track (7), comprising a first drilling tool (8-1) for drilling holes in a second direction (8-2), which second direction (8-2) is perpendicular to the main axis (5) andthird drive means for positioning the first drilling means (8) along the guide track (7); second drilling means (9) mounted on the rotary arm (4), comprising a second drilling tool for drilling holes in a third direction (9-2), which third direction (9-2) is parallel to the main axis (5).

A drilling system may include a plurality of robotic drilling units. Each one of the robotic drilling units may include a drill end effector positioned inside a barrel section. The barrel section may be configured as a composite sandwich structure having an inner face sheet. The robotic drilling units maybe operable in synchronized movement with one another to drill a plurality of perforations into the inner face sheet using the drill end effectors in a manner providing a predetermined percent-open-area of the inner face sheet.

A mechanical cutting device cuts twisted strips of foods such as potatoes. The device comprises twisted cutting tubes, each having a ring secured at a distance from the cutting end. A plurality of such tubes may be arranged in an array, which may be supported by plates having an array of tube-supporting orifices. The cutting tubes are supported for rotation in such manner that, when force is exerted on the tubes to insert the tubes into the food, the tubes rotate as they cut into the food obtaining as result twisted strips of food.
