The Study on the Effects of Physical Factors on the Machinability of GDL-4 Tool Steel

Abstract:

GDL-4 is a new kind of tool steel, but the machinability was the key factor for the application of it. In order to improve the machinability of GDL-4 tool steel, the factors influencing the machinability, such as the thermal property, work hardening exponent, carbides were studied comparing with M2 in this paper. The results show that under the same cutting condition, the thermal property is the key factor which makes the machinability of GDL-4 worse, and Si is the key element affecting the thermal property.
