Chapter 12: Milling Cutters and Operations - American Machinist
Jun 28, 2020 · Cutting Tool Applications, Chapter 12: Milling Cutters and Operations. June 28, 2020. Milling is a process of generating machined surfaces by progressively removing a predetermined amount of material from the workpiece, which is advanced at a relatively slow feedrate to a milling cutter rotating at a comparatively high speed. George Schneider.
Chapter 8: Drills and Drilling Operations - American Machinist
Jun 27, 2020 · Cutting Tool Applications, Chapter 8: Drills and Drilling Operations. Drilling is the process most commonly associated with producing machined holes, because it is simple, quick and economical. Drilling is one of the most complex machining processes.

Chapter 17: Grinding Methods and Machines - American Machinist
Jun 29, 2020 · Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required.
Cutting Tool Applications, Chapter 15: Saws and Sawing
Jun 29, 2020 · Sawing Sawing is a process wherein a narrow slit is cut into the workpiece by a tool consisting of a series of narrowly spaced teeth, called a saw blade. Sawing is used to separate work parts into two or more pieces, or to cut off an unwanted section of a part. These processes are often called cut-off operations and since many manufacturing projects require cut-off operations at some point in ...
5 Common Machine Shop Injuries, and How to Prevent Them
Nov 27, 2019 · 5. Poor guarding techniques — When it comes to heavy machines, a correctly placed guard or barrier can be the difference between safe operation and serious injury, like loss of a limb. It goes beyond having machine guards in place, however. Sometimes the right system exists but malfunctions, or does not correctly identify hazard situations, such as someone’s finger sitting in a saw or gear ...
Chapter 4: Turning Tools and Operations - American Machinist
Jan 19, 2010 · Cutting Tool Applications, Chapter 4: Turning Tools and Operations. Jan. 19, 2010. Turning is used to generate cylindrical surfaces: generation of surfaces oriented primarily perpendicular to the workpiece axis are called facing. In turning, the direction of the feeding motion is predominantly axial with respect to the machine spindle.
Cutting Tool Applications, Chapter 14: Broaches and Broaching
Jun 29, 2020 · A broach is a long multi-tooth cutting tool with successively deeper cuts. Broaching is used to machine internal and external surfaces, such as holes, keyways, and teeth of internal gears. The broaching process, similar to shaping with multiple teeth, is used to machine internal and external surfaces such as holes of circular, square, or ...
Chapter 10: Boring Operations and Machines - American Machinist
Jun 28, 2020 · Cutting Tool Applications, Chapter 10: Boring Operations and Machines. Boring increases the inside diameter of a hole, and achieves three things: sizing, straightness, and concentricity. Boring, also called internal turning, is used to increase the inside diameter of a hole. The original hole is made with a drill, or it may be a cored hole in a ...
Choosing the Right Coolants and Lubricants for Machining
Dec 5, 2023 · The right choice depends on many factors. Cooling and lubricating the workpiece using cutting fluids is essential to the machining process. There is a formulation for every application, material, and type of operation, from copper plumbing fittings to titanium jet engines and airframes. The right choice for a specific type of cutting fluid ...
