What is the cutting edge of a tool responsible for?

• A. Holding the tool in place
• B. Engaging the workpiece and removing material
• C. Providing stability to the machine
• D. Controlling the speed of the cut

Answer: (B)

The cutting edge of a tool plays a crucial role in machining processes by engaging with the workpiece and removing material. This is accomplished as the cutting edge contacts the material, creating shear forces that shear off chips from the workpiece, thereby shaping it according to the desired specifications. The design, geometry, and sharpness of the cutting edge directly influence the efficiency of material removal, surface finish, and tool wear rates. In contrast, holding the tool in place is typically managed by the tool holder or machine setup rather than the cutting edge itself. Stability is maintained through the machine structure and workholding systems, which further ensures accurate machining operations. Additionally, while the speed of the cut can be monitored and adjusted during machining, it is not a function of the cutting edge, but rather relates to machine settings and operational parameters.
