Development of Simulation-Based Learning: G-Code Programming for CNC Milling in Vocational Colleges

Abstract

Traditional teaching approaches for G-code programming of CNC milling machines can be difficult for students to visualise the machine movements related to G-Code. G-code programming for CNC milling is one of challenging concepts, requires an in-depth understanding and experience with the movement of the cutting tool. Simulation-based learning is an innovative teaching and learning method that can help students comprehend G-code CNC milling machines. The DDR model is used in the development of G-code simulation of a CNC milling machine and consists of three main phases such as requirement analysis, design and development and evaluation. The simulation was design and develop using Articulate Storyline 360. The benefit using Articulate Storyline 360 its ability to integrate several interactive media into single application. Expertise review was conducted by experts in the field, as well as student evaluation. The feedback shows that the simulation content is well aligned with the vocational college syllabus. Its also stated that the simulation easily to understand and use. Learning by simulation could possibly make students to understand the complex process.
