Computer Numerical Control for Latin American Metalworkers: Analysis of a Training Intervention

Abstract

Industrial digitalization requires highly skilled personnel in Computer Numerical Control (CNC) to address the challenges of precision and automation associated with Industry 4.0. The purpose of this study was to evaluate the impact of a training intervention focused on CNC in order to strengthen the professional competencies of metal mechanics in Guayaquil and Caracas. Methodologically, a quantitative approach with a quasi-experimental design was applied under the ADDIE instructional model. The program was delivered in a hybrid modality over 100 academic hours with 109 participants. The dimensions assessed included technical knowledge, design/simulation, and practical application, using a Likert-type questionnaire. The main results showed statistically significant differences (p < .001) across all dimensions after the intervention. When evaluated by the trainers, the experimental group reached “strongly agree” levels in technical mastery, whereas the control group maintained ratings of disagreement from the trainers. It is concluded that the program achieved its objective, demonstrating that it is an effective tool for standardizing competencies and improving professional performance in the industrial sector
