Other less significant factors that affect chip formation are coefficient of friction and the surface finish of cutting tool. The chips produced during the machining can be broadly classified into the following types.
The type of chip formed highly depends upon the tool geometry, the material of the workpiece to be machined and machining environment. The coefficient of friction between the cutting tool and surface of workpiece also affects the chips formation process.
cutting fluids are cooling, lubrication, removing chips and metals from the tool/work piece interface, flushing, prevention of corrosion. Cutting fluids are used in machine shops to improve the life and function of cutting tools.

A chip breaker is a feature in the face of the insert that disrupts the flow of chips such that they break into short segments, rather than forming a long, stringy chip. 5.
The chip formation process implies that a fresh metal interface is continually produced between the tool material and the workpiece at varying cutting forces, angles and temperatures. When a cutting edge performs its metal cutting function properly, it deforms some of the workpiece material plastically and then pushes it off. Chips separate in either of three ways: they break by themselves

This paper looks at the process of chip formation in metal cutting as being dependent not only on the work piece material but, even on the micro and macro structures of the work piece materials.
progress in metal cutting can be associated with the introduction of high-speed steel tools by Taylor and the later use of cemented carbide tools (Schroter 1923). Each of these permitted a large increase in the rate of metal removal and
Orthogonal cutting: when chip flows along orthogonal plane, In machining like turning, shaping etc by single point turning tool, the metal removal is accomplished mainly by the principal cutting edge. But the auxiliary cutting edge also takes part in machining to some extent depending upon the auxiliary cutting edge angle, φ 1 and the magnitude of feed, s o, as indicated in Fig. 6.4. A

Swarf, also known as chips or by other process-specific names (such as turnings, filings, or shavings), are pieces of metal, wood, or plastic that are the debris or waste resulting from machining, woodworking, or similar subtractive (material-removing) manufacturing processes.
The material you’re working with and type of project you’re completing will determine which of the different types of band saws to use. Vertical , horizontal, meat, timber, and metal, cover just some of the band saws available.
Continuous chips are formed by the continuous plastic deformation of metal without fracture in front of the cutting edge of the tool and is formed by the smooth flow of the chip up the tool face. Mild steel and copper are considered to be most desirable materials for obtaining continuous chips. The chips obtained have same thickness throughout. This type of chip is the most desirable. Since it

There are two types of metal cutting blades that most circular saws accept. The first is an abrasive, metal cut-off discs that have a mineral grit, like carbide, which line the edges of the disc allowing it to slice through metalworking projects and are designed to withstand the pressures of the task, making it more durable than a regular blade.
The right hand spiral cut of the flutes acts to force the swarf away from the cutting teeth to the rear of the flutes and out of the hole. They are better on materials which form long continuous stringy swarf, rather than chips.
The chips come out without fracture in the form of either long string or bend into a tight roll. If this chip hit finished parts of the work, it spoils the finished surface. To avoid this, a If this chip hit finished parts of the work, it spoils the finished surface.
The three kinds are just basic types of cutting. The actual cutting chips are mostly the composite form among the three; And the crumbs of blade caused by cutting is the form other than the three.
