Effect of Chip Breakers on the Cutting Force During the Machining of Steel C45

Abstract

The paper deals with the dependence of cutting force on the breaker of an indexable cutting insert (ICI). The experiment monitored individual cutting force components for different insert breakers, cutting speeds and feed rates during machining. The cutting depth remained constant. The tool holder, material and coating of the indexable cutting insert was also identical.

Efficiency of Kinematic Chip Breaking on a CNC Lathe

“…When cutting with constant parameters, the invariance of the cutting speed, feed and depth is ensured within the limits of this technological operation. In this case, they mainly use methods of mechanical breaking of chips without the supply of additional energy, which is carried out by adjusting the cutting modes and geometry of the cutter, as well as with the help of notches and ledges, which that change the movement of the chips in the direction of its steeper twisting [1].…”

“…The simulation of the process of chip breaking in the direction of axial feed is carried out on the mathematical model of the cutting tool elastic system in the form of a system of differential equations (1), which takes into account the elastic-damping characteristics of the elements of the dynamic scheme and, using expression (2), the kinematic characteristics of the chip breaking process and the influence of one of sources of self-oscillations during cutting -machining on the previous trace (3).…”
