A method for manufacturing a comb-shaped toothpick structure includes cutting a wooden block by a rotary cutter having a plurality of dies to form a plurality of toothpick shapes arranged in a row. Each toothpick shape includes a top edge formed by a cutter groove between two dies. Each toothpick shape further includes at least one stepped portion formed by at least one stepped cutting portion of one of the dies. The bottoms of the toothpick shapes are connected to each other. A bottom groove is located between two adjacent toothpick shapes and is formed by a blade of one of the dies. The toothpick shapes is further cut by partial cutting at an end of the toothpick shapes to form a front end of each toothpick shape. The toothpick shapes are cut from the wooden block to obtain a toothpick structure including a plurality of toothpicks.

Saw system, including methods and apparatus, for cutting pieces of stock to be installed end-to-end to form miter joints. In some embodiments, the saw system may include a computer that determines an appropriate saw pivot angle for cutting a proximal end of a second piece of stock, based on a corner angle entered for cutting a distal end of a first piece of stock. In some embodiments, the saw system may compensate for an offset pivot axis of a saw device based on entered lengths of cut first and second pieces generated respectively with the saw device pivoted to the left and to the right.

An axially elongate dental machining portion includes a machining region machinable by a dental machining device, and a fixing region for fixing the axially elongate dental machining portion to a holder of the dental machining device. In the fixing region is a fixing projection oriented transversely relative to a longitudinal axis. In a condition of the machining portion being mounted in the holder, the fixing projection bears against a holding nose positioned in complementary relationship on the holder. The machining region has a machinable surface which has a maximum spacing relative to the longitudinal axis, measured normal to the longitudinal axis, and the fixing projection has a maximum spacing relative to the longitudinal axis, measured normal relative to the longitudinal axis, that is greater than the maximum spacing of the machinable surface relative to the longitudinal axis.

A method for producing gears, wherein in a first step a set of teeth is formed by means of a skiving wheel rotationally driven by a tool spindle in a workpiece gear rotationally driven synchronously thereto by a workpiece spindle, wherein the workpiece spindle and the tool spindle are at an axis intersection angle to each other and the advancement occurs in the tooth-flank extension direction, and wherein in a second step at least some teeth of the set of teeth are machined by means of a tooth-machining tool. A combined tool is used, in the case of which the toothmachining tool and the skiving wheel are fixedly connected to each other. Between the two steps, the combined tool remains connected to the tool spindle and the workpiece gear remains connected to the workpiece spindle. Between the two steps, merely the relative position of the tool spindle in relation to the workpiece spindle and the rotational speed ratio of the two spindles are changed.

The invention relates to a method for repairing an aircraft or gas turbine component, wherein the method comprises the following automated steps: a) checking the component for cracks by means of an optical measurement method, wherein determined geometry and/or damage data are stored with reference to the component, b) generating an adaptive processing strategy on the basis of the determined geometry and/or damage data in a data processing unit, c) machining the component, d) determining the changed geometry data of the component, e) performing repair welding, f) checking the component for cracks by means of an optical measurement method.

A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.

A regenerating method of a cutting blade to be repaired includes a chamfering step of chamfering a leading edge part and side edge parts of a cutting blade, a build-up welding step of welding a build-up on the chamfered leading edge part and the chamfered side edge parts, and a processing step of regenerating and processing build-up welding portions of the cutting blade into a specified shape of the leading edge part and the side edge parts, and of the build-up welding portions formed on the side edge parts, such that a dimension L1 of a lateral build-up weld zone is 1 to 3 times a dimension L2 of an outer build-up weld zone.

Systems and methods for adding buoyancy to an object are described herein. A buoyant material may be enclosed inside a flexible container, heated, and inserted into a free flooded cavity inside the object. The flexible container may then be formed to the shape of the cavity. After the flexible container is formed to the shape of the cavity, the flexible container may be cooled. The flexible container may hold a pre-determined amount of the syntactic material that provides a fixed amount of buoyancy. According to another aspect, systems and methods for packing a vehicle are described herein. In some embodiments, a buoyant material may be molded into the shape of a hull of a vehicle, and a plurality of cutouts may be extracted from the buoyant material which are specifically designed to incorporate one or more instruments.
