Abstract
Tool edge preparation can improve the tool life, as well as cutting performance and machined surface quality, meeting the requirements of high-speed and high-efficiency cutting. In general, prepared tool edges could be divided into symmetric or asymmetric edges. In the present study, the cemented carbide tools were initially edge prepared through drag finishing. The simulation model of the carbide cemented tool milling steel was established through Deform software. Effects of edge form factor, spindle speed, feed per tooth, axial, and radial cutting depth on the cutting force, the tool wear, the cutting temperature, and the surface quality were investigated through the orthogonal cutting simulation. The simulated cutting force results were compared to the results obtained from the orthogonal milling experiment through the dynamometer Kistler, which verified the simulation model correctness. The obtained results provided a basis for edge preparation effect along with high-speed and high effective cutting machining comprehension.

With the rapid development and evolution of cutting technology, the performance of cutting tools has become an extraordinary research topic
It was worth being noted that cutting edges were mainly categorized into symmetric or asymmetric edges, while asymmetric edges have been usually characterized by the form factor K for characterization.[2]
It was observed that the numerical error of cutting force, as measured by simulation analysis and milling experiment, was basically within 20%, while the variation trend of cutting force between simulation analysis and milling experiment was basically the same
Summary
With the rapid development and evolution of cutting technology, the performance of cutting tools has become an extraordinary research topic. It was intended to investigate the impact of diverse parameters, including form factor K, spindle speed, feed per tooth, axial, and radial cutting depths on the cutting force, the tool wear, cutting temperature, and quality of the machined surface through the orthogonal cutting simulation.
