2. Rake angle - Wikipedia

   en.wikipedia.org/wiki/Rake_angle

   Zero rake: A tool has a zero (or neutral) rake when the face of the cutting tool is perpendicular to the cutting edge at inner side. Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: Make the tool more sharp and pointed. This reduces ...

3. End mill - Wikipedia

   en.wikipedia.org/wiki/End_mill

   There are variations of these tool types as well. There are four critical angles of each cutting tool: end cutting edge angle, axial relief angle, radial relief angle, and radial rake angle. Depending on the material being milled, and what task should be performed, different tool types and geometry may be used.

4. Turning - Wikipedia

   en.wikipedia.org/wiki/Turning

   A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action. Lathes can be divided into three types for easy identification: engine lathe, turret lathe, [5] and special purpose ...

5. Milling cutter - Wikipedia

   en.wikipedia.org/wiki/Milling_cutter

   Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).

6. Tool bit - Wikipedia

   en.wikipedia.org/wiki/Tool_bit

   Typical hand ground cutting tool angles for the lathe. Back rake is to help control the direction of the chip, which naturally curves into the work due to the difference in length from the outer and inner parts of the cut. It also helps counteract the pressure against the tool from the work by pulling the tool into the work.

7. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force 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 ...
