Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the workpiece ...

Cutting tools come in a range of sizes, materials, and geometry types. It is generally more efficient to use a combination of different toolpaths and tools to achieve a detailed model rather than assuming that a small tool with a smaller stepover is the only way. Often, a larger tool can achieve better finish results.

Grinding a tool provides both a sharp cutting edge and the shape needed for the cutting operation. When the purpose for the rake and relief angles on a tool is clearly understood, then a tool suitable to the job may be ground. Left-hand tools are shaped just the opposite of right-hand tools (Figure I-80).

Cutting tools for metalcutting have many shapes, each of which are described by their angles or geometries. Every one of these tool shapes have a specific purpose in metalcutting. The primary machining goal is to achieve the most efficient separation of chips from the workpiece. For this reason, the selection of the right cutting tool geometry is critical.
