A forming tool for forming leading edges of turbine blades is disclosed. In various embodiments, a forming tool may comprise a cylindrically-shaped body having a notch around the circumference of the cylindrically-shaped body. The notch may be positioned perpendicularly to a center axis of the cylindrically-shaped body. Further, the notch may have a notch contour with an upper notch contour and a lower notch contour, and where the notch contour is a relief of a selected turbine blade leading edge. The forming tool may be a grinding tool or a cutting tool. Moreover, a forming process may comprise forming, by a forming tool, a first portion of a turbine blade leading edge with a rough edge result, and forming, by a milling cutter, a second portion of the turbine blade leading edge with a rough edge result.

A processed article is manufactured with a tool including a cutting blade. The cutting blade is arranged to be in contact with two machined segment surfaces so that two contact points are defined between the two machined segment surfaces and the cutting blade in a corner. A machining pitch is set in a pick feed direction of the tool at the corner to a first machining pitch for when a part of the cutting blade corresponding to a projected shape of a side surface of the cutting blade having a first curvature radius is a cutting point. A cut is performed along a feed direction in the two adjacent machined segment surfaces successively at the corner so that the tool proceeds toward the corner in one of the machined segment surfaces and away from the corner in the other one of the machined segment surfaces.

A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process is disclosed. In various embodiments, the cutting system includes a cutting component having an abrasive surface configured to remove the excess material along a down-facing surface of the channel and a smooth surface configured for sliding contact with an up-facing surface of the channel; and a motive component configured to urge the cutting component through the channel.

A method for manufacturing a built-up object, in which the built-up object includes a plurality of blades provided around a shaft body at circumferential intervals, and concave portions provided between adjacent ones of the blades, each of the concave portions having a curved shape in a section perpendicular to an axial direction, the method includes: a building step of depositing weld beads obtained by melting and solidifying a filler material on a circumferential surface of a base material having a circular shape in a sectional view and having a larger diameter than a bottom portion circle passing through bottom portions of the concave portions, thereby forming built-up portions to serve as the blades; and a cutting step of cutting parts of surfaces of the built-up portions and the circumferential surface of the base material, thereby forming the blades and the concave portions between the blades.

This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.
