1040 – 04 – Why Machinability is Key?

1m

In order to determine the machinability of a material, you must consider many different cutting conditions. These include cutting forces, cutting temperatures, feed and speed, and other properties of the metal, including how hard it is, its strength, and ductility.

The biggest advantage of using proper materials with better machinability is that it improves tool life. Materials that have low machinability are likely to eventually harm the tool, causing wear and, eventually, tool failure. Lower machinability can also be responsible for accelerated tool wear like thermal cracking, flank wear or crater wear.
