An Implementation of Analytical Boundary Simulation on Feedrate Scheduling during Semi-Finish Milling

Abstract:

In five-axis milling, determining the continuously changing Cutter Workpiece Engagement (CWE) remains a challenge. All the feedrate calculation method that have been reported need a precise information about Cutter Workpiece Engagement. In this paper, the cut geometry was calculated using an analytical method called Analytical Boundary Simulation (ABS). This method was reported accurate and less expensive in term of calculation time. The cut geometry data was then used to calculate the instantaneous cutting forces. A new mechanistic force model was developed by taken into account the variation of axial depth of cut, the feedrate, the tool orientation, and the helical angle. Analytical boundary simulation and mechanisitic cutting force model were then used to optimize a semi finish machining process using feedrate scheduling. The applicability of the proposed method was verified experimentally and the result show that the calculated cutting forces of feedrate scheduling have a good agreement with those obtained from the experimental work.
