Innovation in the Practical Teaching Mode of CNC Machining Based on the Cultivation of Engineering Ability

Abstract

As the manufacturing industry undergoes transformation towards digitalization and intelligentization, it places higher demands on the systematic abilities of engineering talents. Traditional CNC machining teaching exhibits structural and contextual limitations in cultivating students' abilities to solve complex engineering problems. This research aims to construct an innovative model for practical CNC machining teaching oriented towards engineering ability cultivation. Firstly, by analyzing the core dimensions of engineering ability and the systematic characteristics of CNC machining teaching, a structured mapping mechanism between ability orientation and teaching content is established. Secondly, in view of the shortcomings of the traditional linear teaching model, a path for the transformation of teaching design is proposed, which is driven by technological evolution and aimed at the integration of abilities. Finally, a three-dimensional innovative model framework is systematically constructed, encompassing the design of multi-level ability objectives, a virtual-actual integrated teaching environment, and a continuously iterative evaluation mechanism. This model emphasizes the realization of knowledge integration and ability enhancement within authentic engineering contexts, providing a theoretical reference and practical paradigm for the systematic reform of higher engineering practice teaching.
