The correct answer is option 'C', which states that tool signature is the procedure adopted for describing various tool angles. In the field of mechanical engineering, tool signature plays an important role in understanding and identifying the characteristics of a cutting tool. It consists of a set of numbers and symbols that provide information about the angles and dimensions of the tool.
The tool signature is used to describe the various angles associated with a cutting tool. These angles include:
1. Rake angle: It is the angle between the rake face of the tool and the normal to the machined surface. It determines the direction of chip flow and affects the cutting forces and tool life.
2. Relief angle: It is the angle between the flank of the tool and a line perpendicular to the machined surface. It provides clearance for the tool, reducing friction and minimizing the chance of built-up edge formation.
3. Side cutting edge angle: It is the angle between the side cutting edge of the tool and the machined surface. It determines the direction of cutting forces and affects the chip thickness and surface finish.
4. End cutting edge angle: It is the angle between the end cutting edge of the tool and the machined surface. It affects the cutting forces and surface finish.
5. Nose radius: It is the radius of curvature at the tip of the tool. It reduces the stress concentration and improves tool life.
The tool signature also includes information about the dimensions of the tool, such as the tool height, tool width, and nose radius. These dimensions are important for selecting the appropriate tool for a specific machining operation.
By using the tool signature, engineers and machinists can easily identify and select the right tool for a particular machining operation. It helps in optimizing cutting conditions, reducing tool wear, and improving productivity. Moreover, the tool signature is also useful in tool regrinding or replacement, as it provides a reference for restoring the original tool angles.
In conclusion, the tool signature is a procedure adopted for describing various tool angles. It is an essential tool in the field of mechanical engineering, providing valuable information for tool selection, optimization of cutting conditions, and tool maintenance.
