Strategies for error prediction and error control in peripheral milling of thin-walled workpiece

Finite Element Analysis of Machining Thin-Wall Parts: Error Prediction and Stability Analysis

“…Ratchev et al [3,11] proposed a flexible force model for machining dimensional form error prediction of thin-wall components. Here, the thermal deflection is introduced into the the flexible force model to consider the temperature effects.…”

“…For a certain surface generation line, the steps adopted to calculate the error distributions can be found in Ref. [3]. …”

“…Machining is a key process since it is easy to result in deflection and chatter [1,2]. In stable machining, surface dimensional error due to the workpiece deflection affects machining precision [1,3]. In unstable machining, the chatter becomes a critical problem for high surface quality.…”

Numerical robust optimization of spindle speed for milling process with uncertainties

“…But the method adopted there is heuristic and the detailed mathematical programming model is absent. Wan et al [11] developed a linear programming model to increase the cutting efficiency and satisfy the tolerance in the meantime. The work is successful based on the fact that the explicit linear relationship expressions of the part error in terms of cutting parameters, i.e.…”

“…So the method proposed in Ref. [11] cannot be adopted directly to tackle the cutting parameters optimization problem taking the spindle speed into account.…”
