Evaluation of 3-Axis and 5-Axis Milling Strategies When Machining Freeform Surface Features

Abstract

The article deals with the comparison and evaluation of milling strategies, which are available in CAM systems and are used for the production of components with freeform surfaces. For the purpose of the experiment a test sample with a repeating shape feature was designed. First half of the test sample shape features were machined using 3-Axis milling strategies while second half was performed with strategies available on 5-Axis CNC machining centre. Simulated machining times as well as virtually machined surfaces using color maps with deviation values were evaluated by employed CAM software. Obtained data was used to evaluate the performance of 3-Axis and 5-Axis milling centre both individually and mutually. These results will be used to compare software data with data obtained from real sample production. The main goal is to verify the reliability of the results provided by CAM systems in the production of parts with freeform feature surfaces.

Influence of Tool Inclination and Effective Cutting Speed on Roughness Parameters of Machined Shaped Surfaces

“…In the production of complex, shaped surfaces by milling, not only the method of clamping the part and the choice of strategies and tools, but also the choice of the CNC machine itself plays an important role. The main advantage of using 5-axis milling strategies is changing the position of the axis of the milling tool with respect to the machined surface to ensure suitable cutting conditions [1]. The most used tools for finishing operations for 5-axis milling are copying tools.…”
