A kit for making an aperture in an object of interest comprises: a hand-held tool configured for securing a milling cutter therewithin and a guiding member conformally shaped to the aperture. The guiding member is securable to a portion to be removed of the object of interest. the guiding member has a rim. The hand-held tool is provided with a bulge guidable by the rim such that such the milling cutter, when being manually movable along the rim, cuts the aperture in the object of interest.

An end mill having a plurality of cutting edges on a surface of a rod-shaped main body is rotated about its longitudinal axis and is moved relative to a workpiece in a feed direction tangential and orthogonal to the longitudinal axis along the workpiece. The end mill is also moved relative to the workpiece in a reciprocal manner in the axial direction while it is moved in the feed direction. In this way, a plurality of dimples are formed by the end mill on the workpiece, such that the dimples are relatively spaced apart from each other on the workpiece. The plurality of dimples are arranged side by side in the feed direction along a line inclined at a predetermined angle relative to the feed direction so as to be offset while partially overlapping with respect to each other in the axial direction.

A plurality of dimples are formed on a processing surface of a workpiece. An aspect ratio of each dimple is greater than or equal to 5.0 and less than or equal to 50.0. The aspect ratio is a ratio of a length of the dimple measured in a longitudinal direction to a lateral width of the dimple measured in a direction perpendicular to the longitudinal direction.

In a method of setting heat-resistant alloy cutting conditions used to set cutting conditions under which a heat-resistant alloy is cut with a cutting tool, the cutting tool has a long shaft mounted on a spindle and extended in the axial direction and teeth formed on the shaft. The cutting conditions include a radial direction cutting amount of the cutting tool in the radial direction. When the radial direction cutting amount in which one tooth is constantly in contact with the heat-resistant alloy is given as a smallest radial direction cutting amount and the radial direction cutting amount in which three or more teeth are not in contact with the heat-resistant alloy is given as a largest radial direction cutting amount, a radial direction cutting amount of the cutting tool is set in the range from the smallest radial direction cutting amount to the largest radial direction cutting amount.

A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material includes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

A ratchet structure includes a body. The body is provided with a plurality of equally spaced ratchet teeth extending along the axial direction, and an annular groove is formed on the body to divide the body into a head portion and a body portion. The ratchet teeth are located on the body portion, and a predetermined groove is provided between the ratchet teeth and the annular groove. With the predetermined groove, when the milling cutter mills out the groove in the body portion and enters the predetermined groove, the waste chips connected to the annular groove bottom surface of the annular groove will be surely cut off, thereby solving the problem that it is difficult for the ratchet wheel to get rid of the waste chips.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A paste retainer system is disclosed for use in a paste printing system, said paste retainer system comprising a flexible attachment means for attaching a paste retainer to a squeegee holder via a flexible main body.

A method of forming a microneedle array can include forming a sheet of material having a plurality of layers and micromilling the sheet of material to form a microneedle array. At least one of the plurality of layers can include a bioactive component, and the microneedle array can include a base portion and plurality of microneedles extending from the base portion.

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.
