In modern manufacturing, the efficiency of Computer Numerical Control (CNC) machines is heavily dependent on minimizing non-productive time. The tool changing process—switching between different cutting tools—is a critical factor influencing cycle time and production costs. This paper proposes the design and simulation framework for a cost-effective, arm-type Automated Tool Changer (ATC) tailored for Small and Medium Enterprises (SMEs). The proposed mechanism utilizes pneumatic actuation and electronic control to ensure precise, rapid tool replacement. The methodology employs SolidWorks for 3D modeling and kinematic synthesis, followed by Finite Element Analysis (FEA) using ANSYS to validate structural integrity under dynamic loads. The design focuses on modularity, reducing the tool-to-tool change time to under 5 seconds, and replacing manual intervention to enhance operator safety and machining precision.
