TOP RAKE Meaning and
Definition
-
Top rake is a term commonly used in the field of cutting tools and machining processes. It refers to the incline or angle formed between the top surface of a cutting tool or insert and a reference plane, usually the workpiece surface.
In the context of lathe tools, the top rake angle is determined by the angle at which the top surface of the tool is inclined backward from the cutting edge. It plays a crucial role in determining the efficiency and effectiveness of metal cutting operations. The top rake angle helps in controlling the chip flow, enhancing tool life, reducing cutting forces, and improving surface finish.
A positive top rake angle means that the top surface of the cutting tool slopes upwards from the cutting edge, while a negative top rake angle means the opposite – it slopes downwards. The selection of the appropriate top rake angle depends on various factors such as the material being machined, the cutting conditions, and the desired outcome.
When machining soft materials, a higher positive top rake angle is usually preferred to achieve better chip control and reduce cutting forces. Conversely, in the machining of hard materials, a lower or even negative top rake angle might be recommended for improved tool life and surface finish.
Overall, top rake is an important parameter in cutting tools as it influences chip formation, cutting forces, and tool life, ultimately affecting the efficiency and quality of machining operations.

Etymology of TOP RAKE
The word "top rake" does not have a specific etymology as it is not a commonly used or recognized term. "Rake" typically refers to the inclination or angle of something, such as the slope of a roof or the angle of a cutting tool. However, the term "top rake" on its own does not have a widely-known origin or meaning. It is possible that it may be used in a specific industry or context with a particular meaning, but without further information, it is difficult to determine its specific etymology.
