Cutting tool (machining)

There are several different types of single-edge cutting tools that are made from a variety of hardened metal alloys that are ground to a specific shape in order to perform a specific part of the turning process resulting in a finished machined part.

This is known as the tool path which is determined by the axis of the table that is holding the workpiece in place.

This table is designed to accept a variety of vises and clamping tools so that it can move into the cutter at various angles and directions while the workpiece remains still.

[1] Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip.

In order to have a long working life, all of the above must be optimized, plus the speeds and feeds at which the tool is run.

Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades.

In these, the cutting edge consists of a separate piece of material, either brazed, welded or clamped on to the tool body.

Common materials for tips include cemented carbide, polycrystalline diamond, and cubic boron nitride.
