Abstract:

This paper presents research conducted to model and analyze the peripheral milling of thin titanium plates. Impact tests are performed and the vibration characteristics of a thin titanium plate are modeled empirically. The force process is described by a mechanistic model and experimental data are used to determine the model parameters. The Particle Swarm Optimization technique is used to determine the parameters of the plate vibration and force process models, which are combined to create a complete model of the thin titanium plate peripheral milling operation. The models are validated experimentally and the results showed excellent agreement between the simulation and experimental results. A process planning scheme for peripheral milling of thin titanium plates is developed and applied. In this scheme, integer numbers of widths-of-cut and depths-of-cut are used and the optimal helix angle and feed are computed for each combination of width-of-cut and depth-of-cut. The process planning test case revealed the optimal material removal rate decreases as the width-of-cut decreases.
