An Analytic Hierarchy Process-Based Multicriteria Model for Component Selection in a Computational Numerical Control (CNC) Machine

The modernization process of a CNC machine entails multifaceted and critical component selection. This study proposes a multicriteria model based on the Analytic Hierarchy Process (AHP) to address this challenge. It focuses on the selection of CNC software and MCU, considering factors such as quality, vendor support, and technical capability. The CNC machine EP2006 was taken as a case study due to issues related to PCAM software. AHP identified GRBLHAL as the best alternative for CNC software and Teensy 4.1 or T41U5XBB for the MCU. This robust approach takes into account technological evolution, ensuring that the machine remains up-to-date and competitive in an ever-changing environment.
