In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative .
Definition of rake angle – It is the angle of orientation of tool’s rake surface from the reference plane (πR) and measured on some other plane. Its various names based on the plane on which it is measured, effects and functions, typical values, and positive negative and zero rake angle are discussed here.
Significance of Rake Angle: 1. The rake angles may be positive, zero or negative. 2. An increased rake angle will reduce the strength of the cutting edge. 3. Rake angle affects the values of cutting angle and the shear angle. 4. Larger the rake angle, smaller the cutting angle (and larger the shear angle). 5.
Concept of positive rake angle, negative rake angle and zero rake angle of a cutting tool is discussed here. It explains classification of rake angles with diagram and their examples, advantages, disadvantages and applications.
Feb 21, 2021 · The rake angle (γ) is the angle between the rake surface and the reference plane (πR) or perpendicular surface of the workpiece. Rake angle is the most important factor while designing a cutting tool.
Rake angle is a cutting edge angle that has large effects on cutting resistance, chip disposal, cutting temperature and tool life. Effects of Rake Angle. Increasing rake angle in the positive (+) direction improves sharpness. Increasing rake angle by 1° in the positive (+) direction decreases cutting power by about 1%.
Oct 10, 2023 · The rake angle is a pivotal part of the design of a cutting tool. It is defined as the angle of the face of the cutting tool in reference to a line that is perpendicular to the feed direction. There are three main types of rake angles: Positive; Neutral (sometimes called zero) Negative; Various rake angles can be measured from different ...
Rake Angle (Note: The rake angle is the angle between the normal to the surface and the leading face of the asperity, with negative values indicating a tilt toward the direction of travel. From: Tribology for Engineers, 2011
Rake angle is the angle between the cutting tool bit and the cutting chips. This has a large effect on cutting resistance, emission of cutting chips, cutting heat, and service life. Checking and controlling the cutting tool rake is crucial to ensure for proper machining action.
Oct 23, 2022 · There are three different types of rake angles, positive rake angle, negative rake angle, and zero rake angle. The recommended rake angle depends on the tool material, the material to be cut, and the speed and depth of cutting.
