Determination of the Cutting Area considering the Tool Slenderness Ratio for the Development of a 5-axis Impeller Machining Automation CAM Module

摘要

The efficiency of applying 5-axis machining is higher for various products compared to general 3-axis machining, which is restricted to general parts and mold machining. However, impeller machining requires a large tool slenderness ratio to avoid interference with neighboring surfaces. Because such an enlargement of the slenderness ratio causes damage to the tools and deterioration of the quality of products due to the vibration of the tool, it is important to review the cutting characteristics considering the slenderness ratio and to determine the proper cutting conditions. Also, industry has attempted to develop a 5-axis machining automatic CAM module for an impeller that helps inexperienced workers to process the impeller easily by simplifying the process and options for the cutting impeller. The, current status of research on the cutting conditions considering the slenderness ratio to complete a database for a sub-module accounting for the cutting conditions among the components of an automatic CAM module is urgent. Therefore, the purpose of this work is to review the cutting characteristics that influence the cutting of aluminum alloy, the typical material of impeller parts, while also considering slenderness ratio to complete the 5-axis machining automatic CAM module of an impeller and to determine the available cutting area during the roughing and finishing operations.
