Dynamic analysis of cam-type automatic tool changer
Abstract
Abstract The automatic tool changer (ATC), a core component of CNC machine tools, critically influences machining accuracy and productivity through its dynamic performance. To enhance ATC performance and guide drive system optimization, this study establishes a systematic dynamic model. We first derive the kinematic relationships between the input motion and the position, velocity, and acceleration of each moving component. Using the principle of virtual work, a dynamic model is then developed to relate the driving torque to the inertial loads of the mechanism. The model is validated through torque experiments and numerical examples, confirming its accuracy and revealing shortcomings in the current drive configuration.
