Description:

Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on 45steel, cast iron, nonferrous materials, plastics and other tough-to-machine materials.

Application:

The oldest milling cutter designs are of double negative geometry. Inserts were totally flat, so the cutting rake or "top rake" was also negative. Thanks to the advancements in design and pressing of carbide inserts, another geometric dimension has been added to milling operations through the insert geometry itself. These insert geometries have further enhanced the milling cutter performance.

While it is known that negative inclinations of the insert are the strongest way to present the insert to the workpiece, it is also true that positive top rakes make for a freer, quieter, lower horsepower cut. Designers of round insert cutters have been able to maintain the strength of negative inclination, while not compromising on a high positive top rake. This is due to the pressed-in geometries of the inserts (Figure 7). By putting positive angles and optimized edge preps on the round inserts, security is maintained and a free cutting action is produced.

In addition to normal milling operations, there are certain applications that are particularly damaging to carbide. Here are some of the most difficult jobs that demand a lot of strength from the shape of the insert:

• Milling of castings, where the axial depth often varies throughout the cut,
• Workpieces with hard spots or inclusions that cause unpredictable insert life,
• Raw materials that are flame or plasma cut, leaving very hard surfaces to machine,
• Forgings or castings with slag or scale on the surface that can result in the notching of the insert,
• Hardened steels, tool steels and cast irons, and
• Heat resistant materials like Inconel, titanium and Hastelloy.

Clearly the shape of the round insert is the major reason for its strength and reliability. One major reason for the success of the round insert in so many applications is that the axial and radial cutting forces can be managed by changing the axial depth of cut. A high radial cutting force can cause vibration and chatter. Conversely, a high axial force can cause the workpiece to move in its fixturing and cause poor tolerances. With the use of traditional milling cutters, the lead angle dictates the kind of cutting force produced.
