A cutting tool includes: a cutting part including a cutting edge having a linear shape; and a fitted part including a fixed section to which the cutting part is fixed, and a fitted part body to be fitted to a cutting device. The cutting edge is located perpendicularly to a virtual line passing through a central axis of the fitted part body, on a plane that is perpendicular to the central axis of the fitted part body. A center of the cutting edge in its longitudinal direction is located on the virtual line.

A method for producing an integrally bladed rotor includes providing imaginary front and rear lattice points on the ridges of the front and rear edges; providing a first imaginary line on positive-pressure and negative-pressure surfaces to connect a first imaginary front lattice point and a first imaginary rear lattice point; providing a second imaginary line on the positive-pressure and negative-pressure surfaces to connect a second imaginary front lattice point next to the first imaginary front lattice point and a second imaginary rear lattice point next to the first imaginary rear lattice point; providing a spiral path on the positive-pressure and negative-pressure surfaces by connecting the first and second imaginary lines with a spiral curve; and cutting the positive-pressure and negative-pressure surfaces by moving a cutting point corresponding to a cutting edge of a turning tool along the spiral path. point around the blade.

A method and downhole tool assembly, of which the method includes measuring a thickness and a location of an outer diameter surface of the tubular at a plurality of transverse planes of the tubular, simulating a cutting process to determine a position for the outer diameter surface of the tubular in a lathe, such that, after the cutting process that was simulated is conducted, the thickness of the tubular is greater than a minimum thickness and an outer diameter defined by the outer diameter surface of the tubular is less than or equal to a maximum diameter, positioning the tubular in the lathe based on the simulation of the cutting process, cutting the outer diameter surface of the tubular to reduce the outer diameter thereof to at most the maximum diameter and thereby form a turned-down region, and positioning the downhole tool on the tubular in the turned-down region.

Positions of both end edges of a weld bead in a bead width direction are measured over the entire circumference of a liner in a circumferential direction of the liner. Based on information on the position of the end edge, bead profile information being information on a shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction is created. Based on this bead profile information, machining information of the liner per rotation of the liner being position information of a cutting tool in the bead width direction per phase in the circumferential direction of the liner is created so that a moving locus of the cutting tool relative to the liner along the circumferential direction of the liner approximates the shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction.

A method of manufacturing, comprising utilizing at least one cycloid machine to machine a component blank, wherein the component blank includes a plurality of pockets, guiding a tool cutting lip of a chisel along a cycloid path relative to the component blank rotating about a component rotation axis in a component direction of rotation, rotating the chisel about a tool rotating axis, wherein the tool rotating axis is arranged offset to the component rotating axis, machining the plurality of pockets, wherein a radial vector to a tool rotation axis that extends through a cutting edge of the tool cutting lip, and dividing the tool cutting lip into a clearance angle portion and into a rake angle portion, wherein the clearance angle portion is configured to be at least twice as large as the rake angle portion of the chisel.

A tool drive unit for a turning device for machining workpieces has a tool holder driven in a displaceable manner along an infeed direction by a first linear motor and driven in a pendular/displaceable manner in a direction transverse to the infeed direction by a second linear motor. Both linear motors have a moving coil/piezo element. The turning device has a main infeed drive, which produces a primary infeed movement of a turning tool in an infeed direction, and has a main transverse drive which produces a primary transverse movement in a transverse direction transversely to the infeed direction. The turning device has a secondary transverse drive whose movements are oriented in the same direction as the main transverse drive, wherein the turning tool and the axis of rotation can be moved towards one another and away from one another by the superimposition of primary and secondary transverse movements.

An assembly and method for mechanically skiving a tube to later form into a medical balloon are provided. The assembly includes a blade holder and a tube guide wherein the blade holder retains the blade in a diagonal relationship relative to the tube guide. A lathe assembly includes a mandrel for extending into a lumen of the tube and fitting into the tube guide. The lathe assembly further includes a spinning mechanism that rotates the mandrel relative to the blade for skiving the exterior surface of the polymer tube. The diagonal relationship allows for precise shaping of a transition portion of the tube, which is located between a medially located un-skived portion of tube and two skived portions located at tube ends. Once the tube is skived, a molding process inflates the un-skived portion into a balloon and stretches the transition portion and the skived portions forming a medical balloon.
