A new metal-cutting tool is developed—reamer-broacher, which improves the cutting process by minimizing adverse factors. By theoretical and experimental studies the regularities of the influence of cutting modes on the quality of processing with the subject tool are established. [ABSTRACT FROM AUTHOR]

In the hybrid burnishing of holes in LS59-1 brass billets, for which grinding is not applicable, experiments are conducted to assess the dependence of the accuracy on the microgeometry of the tool's working surfaces and the composition of the lubricant ensuring wear-free operation of Garkunov–Kragelskii type.

Various methods of attaching stepped thin-walled cylinders in honing are considered. Means of increasing the machining precision of the hole are proposed. In the analysis, the nonuniform deformation of the cylinder by the clamping forces is taken into account, and radial forces simulate the cutting forces. The stress–strain state is determined by the finite-element method using DEFORM-3D (v. 6.1) software. [ABSTRACT FROM AUTHOR]

The article presents a design for a tool block. The cutters of the tool block are located asymmetrically. Cutters carry out butt-end turning of holes. The tool block has a high durability, makes it possible to produce shallow bores with flat bottoms, increases manufacturing capability and precision, and reduces the form of deviation and asperity of a finished surface.

The design of tools with adjustable geometry is analyzed. A design is proposed for a boring tool with a replaceable polyhedral insert in which the lead angle may be varied. This design permits the machining of blind and through holes in the workpiece with the same cutter. [ABSTRACT FROM AUTHOR]

The influence of preliminary deformation on the surface quality of holes produced by broaching is investigated. [ABSTRACT FROM AUTHOR]

Experimental data are presented regarding the influence of the cutting conditions and the working profile of the tool on the surface precision and roughness of deep holes produced by small-diameter (2.05 mm) gun drills with hard-alloy and steel shafts. [ABSTRACT FROM AUTHOR]

The stress state of a unilaterally reinforced hole in a plate under axial extension is analyzed. Such reinforcement does not effectively reduce the maximum stress. [ABSTRACT FROM AUTHOR]
