Machining processes have many parameters that affect the performance, accuracy and the surface quality of the finished product. Most of these parameters would mean very little to someone who just reads or listens about machining without actually seeing them in action. Conventional lectures with power point presentations followed by quizzes would at best make them to memorize them and repeat when asked. But it is the responsibility of the teaching instructor to give the necessary understanding and ability to use the knowledge in the various manufacturing process such as shaping, moulding, material removal process, advanced machining techniques and additive manufacturing process to get them readily employable in the local industries. In order to enhance the student understanding of the course, the delivery methodology and the assessment strategies were designed to include practical / workshop sessions. In these session, the students were trained the basic skills to operate conventional lathe and milling machines. The students were then exposed to witness the effects of the type of cutting tools, tool life, cutting fluids and selection of tools and cutting parameters such as speed, feed and depth of cut on the surface finish produced. By using different material work-pieces they were able to see the effects of varying these parameters on finished quality of the work. They were then exposed to work on CNC machines where they were required to use the parameters they learned to write the G and M codes and to simulate them. The students were then asked to model the component in SOLIDWORKS and convert the model into an STL file for onward printing in a 3D printer. The results were really significantly better and the students were enthusiastic and fully engaged with the work. This paper describes all these in detail, the method of assessment, the results and the student feedback.
