Finite Element Analysis of Micro-Cutting Aluminum 7050-T7451 with the Tool Edge Radius Considered

Abstract:

In this paper, a series of simulation works by finite element method for predicting the temperature and the plastic strain distributions in micro cutting process with the tool edge radius considered were conducted. The workpiece is Aluminum alloy 7050-T7451 and its flow stress is taken as a function of strain, strain rate and temperature in order to reflect realistic behavior in machining process. From the simulation works, a lot of information on the micro-machining process can be obtained, such as cutting force, cutting temperature, distributions of temperature and plastic strain, etc. In addition, explanations for the observed trends are also given.
