File And Pc-Based CNC Controller Using Integrated Interface System (I2S)

STEP file is known as a CAD neutral file which stands for Standard for the Exchange of Product model data for the next generation of data model between CAD/CAM and CNC system. It contains three-dimensional data in ISO 10303-21 format which ultimately all CNC programs can recognize. Now however, not all documents in the STEP file are appropriate for programming CNC G-Code. This paper explicates the design, development and testing of an Integrated Interface System (I2S) using knowledge discovery approach. The objective of this study is to provide helps for understanding the STEP-NC machining operation protocol. The system provides function of reading and extracting applicable data related with the machining functions from STEP file, that eventually write file format Geometrical Code (G-Code – ISO 6983) as an output file. G-Code is known as one of the low-level programming languages in CNC system. The sample of machined block designs from 3D CAD modeler where the features need to be machined from a blank workpiece and saved in the STEP neutral file format. In this work, the simulation in the Mach3 software and physical machining using 3-axis CNC milling machine installed with PC-based CNC controller has been validated

Digital Pedagogy Policy in Technical and Vocational Education and Training (TVET) in Malaysia: Fuzzy Delphi Approach

Digital platforms are one of the technology adoption that is beginning to be used in most vocational colleges today. Services provided through digital platforms are an alternative to conventional methods. However, the use of digital platforms nowadays, among users consisting of vocational college students in Malaysia is still at a less than satisfactory level. Previous studies also focused a lot on the use and acceptance of technology platforms among users in schools only but not in vocational colleges (VC). The aim of the research is to determine the experts’ consensus on the objective of the digital pedagogy policy for Technical Education and Vocational Training (TVET) students especially in vocational colleges which is currently under development. Vocational colleges is one of the Technical Education and Vocational Training (TVET) institutions in Malaysia that offers certificate level and skill diploma education to high school students. Therefore, it is important to identify the policy that will be used. The Fuzzy Delphi Technique (FDT) was used in this research. Ten experts were chosen by utilizing the purposive sampling method. Analysis of the data was using the Triangular Fuzzy Number and Defuzzification process. The findings showed 100% consensus was achieved by the experts for objectives 1 and 3, and 90% consensus was achieved by the experts for objective 2. All of the experts agreed on the elements in the objectives of the digital pedagogy policy for TVET students. Further development of this policy hopefully will help the teachers in improving their knowledge of digital pedagogy and increase their competency pedagogy in order to produce skills oriented workforce among TVET students in Malaysia. Therefore, the results of this study are expected to be used to strengthen the development of e-learning models in the future to help students and educators to use digital platforms in vocational colleges in particular
