Metal Cutting is a guide that discusses the process of metal cutting and its different techniques. The book first gives a short history and introduction to metal cutting, and then discusses the operations and terminologies used in metal cutting; the essential features of metal cutting; and the forces involved. ...
The saw-tooth chip was the last of the major types to be identified. This occurred in 1954 during machining studies of titanium alloys which were then being considered for aerospace applications because of their large strength-to-weight ratio and corrosion resistance. This is a type of chip that forms when very hard brittle materials are machined at high speeds and feeds. Since this is an area ...

(i) the tool is harder than the metal, (ii) the tool is properly shaped so that its edge can be effective in cutting the metal, (iii) the tool is strong enough to resist cutting pressures but keen enough to sever the metal, and (iv) provided there is movement of tool relative to the material or vice versa, so as to make cutting action possible.

Cutting Edge is inclined at an acute angle to tool feed. Here only three force components are considered i.e. cutting force, radial force and thrust force. Hence known as three dimensional cutting. Shear force acts on larger area. Metal Cutting is the process of removing unwanted material from the workpiece in the form of chips Assumptions
BASIC MECHANICS OF METAL CUTTING The basic mechanics of chip-type machining processes (Fig. 13.4.1) are shown, in simplest two-dimensional form, in Fig. 13.4.2. A tool with a certain rake angle a (positive as shown) and relief angle moves along the surface of the workpiece at a depth t 1. The material ahead of the tool is

Mechanics of Metal Cutting The force acting on a cutting tool during the process of metal cutting are the fundamental importance in the design of cutting tools. The determination of cutting forces necessary for deformation the work material at the shear zone is essential for several important requirements:

Abstract. This chapter presents a short analysis of the basics of traditional metal cutting mechanics, outlining its components and the basics of finite element modelling (FEM) of the metal cutting process. Based on a previously proposed definition of metal cutting, advanced metal cutting mechanics considers the power spent in metal cutting as ...

predict how to cut steel was created with modifications allowing predictions of the metal cutting process with any metal. A comparative study was done with 1006 steel, 6Al-4V titanium, 2024-T3 aluminum and OFE copper regarding the differences in tool forces and temperatures that would result if each metal was cut with the same process. A
processes for cutting look very different from each other, the basic mechanism for causing the fracture can be understood by just a simple model called for orthogonal cutting. In all machining processes, the workpiece is a shape that can entirely cover the final part shape. The objective is to cut away the excess material and obtain the final part.

Metal cutting applications span the entire range from mass production to mass customization to high-precision, fully customized designs. The careful balance between precision and efficiency is maintained only through intimate knowledge of the physical processes, material characteristics, and technological capabilities of the equipment and workpieces involved.
