| Summary: | 碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 104 === The objective of this study is focused on the design and development of a five axis machine equipped with automatic changes of rotary tools so as to get rid of traditional imitation concerning the process of shape cutting machining, "people on the machine" and not "machine to people ", automatic processing operations. In addition, the operator production process fatigue and comfortableness are needed to be considered further, and manpower shortage and production efficiency are also needed to be improved in future. Therefore, this study is to improve each manufacturing processes and combines them into a machine that can complete the processes of machining. The primary planning and design is to use five-axis automation subassembly and fast tool change to construct the standards of operating procedures so as to achieve the required production efficiency.
In this study, the appearance of the five-axis tooling machine belongs to a kind of large overhead crane mechanism with the transformation type of TTTRR. In which, Z-axis is the main body, C-axis is hanged to be the main rotation axis and A-axis is the rotation cutter-head to perform cutting experiments for acrylic materials. If surveying the market of tooling machines, such as Germany SIEMENS and Japan FANUC CNC, control systems are very expensive. Therefore, a laboratory self-developed controller is applied. Considering the modes of motion and software analysis, a customized five axis machine with automatic rotary tool changes is designed with TTTRR overhead crane mechanism and integrated with a five axis motion controller.
The experimental verification is to use a five axis contact coordinate measuring machine to do the analysis and comparison of the direct and inverse kinematics derivation paths so as to detect the A-axis at different angles changes controlled to move on X-Y-Z-C motion platform simultaneously, and the attitude parameters of A-axis at the various conditions, X-Y curves of motion are maintained consistently.
